What’s the best tourist SIM card for Japan (2024 guide)

By: Author Kris

Posted on Last updated: January 22, 2024

If you’re headed to Japan and want to stay connected while exploring, we’ve got you covered with the top tourist SIM cards. No need to worry about losing touch with your loved ones or missing out on those Insta-worthy moments.

We’ve spent a lot of time in Japan and traveled all over the country. The first trips we would very often come across a “Handy” phone in our hotel room – a phone we could use throughout our stay. But those days are long gone now.

Nowadays, if you want to stay connected, you better have a local SIM card if you don’t want to rely on public hotspots. And trust me, from experience, we can assure you that a local SIM card is still highly recommended.

There are several spots offering free internet, mainly in the larger cities, and handy apps to connect to WiFi hotspots for free. We share more information on this app in this article. Still, there are still plenty of places that require a data subscription for internet usage.

Whether you prefer the convenience of ordering physical SIMs online and picking them up at the airport or exploring the innovative world of eSIMs, there are numerous ways to ensure you stay connected on your journey.

Japan Tourist SIM cards – The top choices

In this article, we discuss no less than 30 different Japan tourist SIM cards.  All of which have slightly different options.  It’s good to have a choice but with all these different options it is hard to see the forest for the trees.

We discuss all the details of the SIM cards further down in this article but here are our top choices:

For the occasional data user

Most SIM cards offer unlimited data but all providers have implemented a fair usage policy. If you consume more than what is covered by the fair usage policy your data speed will be reduced. Sakura Mobile cannot share the exact details of the fair usage policy, therefor we recommend them for occasional use. Their prices are very competitive but they cannot be used for video streaming or as a hot spot for your laptop.

If you just want to make sure that you can fall back on your data plan if you need it but you already know that you will only have to use it occasionally, these are your best options.

Short stays

At JPY ¥4,000 for 8 days the SIM cards provided by Sakura Mobile are reliable and very cheap. 

The SIM card offers unlimited high-speed data at 4G or 3G speeds.  You will find a very detailed document to check if your mobile is compatible with the local network. Sakura Mobile uses the NTT Docomo network in Japan, generally seen as the best network in the country.

Thanks to the detailed information you can buy this SIM with peace of mind, knowing that it will work once you are there. If you’re still unsure you can pay a supplement for compatibility insurance. With this insurance, you will receive a WiFi device in case the SIM does not work in your phone.

Alternatively, if your phone is incompatible (see our FAQ below) with the NTT Docomo network you can opt for a Mobal SIM that works on both the NTT Docomo and the Softbank network.

Longer stays

If you are 2 of 3 weeks in japan.

For stays of 2 or 3 weeks , you’re in most cases also best off 16 or 21-day cards of Sakura Mobile that can be found on Klook.  At JPY ¥6,000 and JPY ¥6,500 they are the cheapest options that can be found for these durations.

Both SIMs offer unlimited high-speed data at 4G or 3G speeds.  4G is offered in major cities while the 3G is applicable in more rural areas. You will find a very detailed document to check if your mobile is compatible with the local network. Sakura Mobile uses the NTT Docomo network in Japan, generally seen as the best network in the country. It has a coverage of over 99%.

Once you have read through the detailed information you can buy this SIM with peace of mind, knowing that it will work once you are there.

If you’re still unsure you can pay a supplement for compatibility insurance. With this insurance, you will receive a WiFi device in case the SIM does not work in your phone.

Alternatively, if your phone is incompatible with the NTT Docomo network you can opt for a Mobal SIM that works on both the NTT Docomo and the Softbank network.

If you are longer than 24 days in Japan

If you will be in Japan longer than 24 days the 30-day card of Simcard GEEK that costs JPY ¥4,980 is a good buy.  The card comes with 7GB of high-speed data which should be sufficient to cover your needs.  This SIM card also connects to the NTT Docomo network which is generally recognized as Japan’s best network.

Simcard GEEK has a fair usage policy of 3GB/day.

For the heavy data user

If you want to be online the whole day,  enjoy streaming music, or watch YouTube videos, you’re better off with the below SIM cards.  This may also be the case for those who will be sharing your data plan with friends or family members, maybe by means of a mobile WiFi device.

These SIMs also have a fair usage policy. In this case, however, you know the details of the policy and can therefore pay attention to it so that you are not faced with surprises.

Mobal offers SIM cards for 8 or 16 days with an unlimited data plan .  The cards have a fair usage policy which limits high-speed data to 3GB per day. 3GB is quite a lot, it will allow you to browse the internet for 36 hours, stream 600 songs, or watch 6 hours of standard definition video. 

Consuming this amount of data in one day would probably mean that not much time is left to see the many stunning sights Japan has to offer.

Mobal has a SIM with an unlimited data plan for 31 days.   This card has a fair usage policy which limits high-speed data to 3GB per day. 3GB is a lot, in the previous paragraph we gave a small overview of what exactly you can do before you reach this threshold. 

If you go out and discover the city you will probably never consume that much data in one day and if you stay in your hotel you can use the WiFi provided by the hotel.

Sakura Mobile

Sakura Mobile is a reputable Japanese company that specializes in providing wireless services for visitors to Japan. They offer a range of affordable solutions to keep you connected throughout your stay.

They offer English support. Our support question was answered quickly, correctly, and in clearly understandable English.

One standout feature of Sakura Mobile is its compatibility insurance option. For an additional fee of 500 JPY, you can add this insurance to your purchase if you’re unsure whether their SIM will work with your device. This provides peace of mind and ensures that you’ll be able to stay connected without any hiccups.

In the unlikely event that you do encounter connectivity issues, Sakura Mobile offers a solution to those who took the insurance option – an upgrade to a Pocket Wi-Fi device at no extra cost. Alternatively, if you prefer, they can also provide a refund.

You have multiple options when it comes to ordering Sakura Mobile SIMs. You can either purchase them through Klook or directly on their corporate website . While the widest range of options is available on their own site, it’s worth noting that Klook offers certain exclusives not found on the corporate website.

On the other hand, when ordering directly, you can choose from more pick-up locations or have the SIM shipped to any address within Japan, including hotels.

Size : Multi-size SIM cards. Normal, Nano or Micro sim.

Network :  NTT Docomo (3G & 4G)

Shipping :  When you order through Klook the SIM can be collected at Terminal 3 (the International terminal) of Haneda International Airport or Terminal 1 and 2 of Narita International Airport. There is also a pick-up location in the arrival lobby of the Kansai airport.

If you order direct you can have the SIM delivered to hotels and Airbnb’s or collect it at the airport (Haneda, Narita, Kansai, Chubu, New Chitose) or at the office in Shinjuku.

Activation : No activation is required for these SIM cards. They’re ready to use. You just need to insert the SIM and set the APN.  You can download a document that explains how to do this.

Available direct :

Available through Klook :

Japan SIM cards with pick-up abroad (via Klook)

Here are a few extra options for those who live in Thailand, Malaysia, Hong Kong, Vietnam or India.

The below providers offer SIM cards that are either shipped to your home or that can be collected at your airport of departure.

Personally I would prefer to pick-up my SIM in Japan.  This has the advantage that somebody can assist you with setting it up and in the unlikely event that it doesn’t work, you would be able to look for an alternative or arrange a refund on the spot.

A pick-up abroad might, however, be a convenient option if you don’t want to lose time collecting your SIM upon arrival.

Buying a SIM card in Japan

Don’t worry if you’re already in Japan when you’re reading this. 

It’s also possible to buy a tourist SIM card in BIC Camera and Yodobashi Camera stores as well as at Narita and Haneda airports. 

You can even order one online and pick it up in several locations in downtown Tokyo, Kyoto, Osaka as well as other cities.

At the airport

If you want to start using your SIM card immediately you can buy one at the airport.

In the arrivals hall are sales counters from various operators and they will certainly be able to assist you in English. 

The drawback is that your choice will be more limited than in the shops in the city and you will be paying more, as is always the case at airports.

BIC camera also operates one small store in Narita and 2 in Haneda airport terminal 3 (see here and here ).  The sales points from the operators will likely be able to better assist you and give you advice while the stores from BIC camera will likely be cheaper.

In the cities

Another option to buy a SIM card in Japan would be to head to one of the BIC Camera or Yodobashi Camera stores in the cities. 

They sell various prepaid SIM cards for Japan tourists.  Usually, someone will be able to assist you in English but don’t expect the store personnel to speak the same level of English as they would at the airport. 

If you know what you need they will be able to point you to the correct package or confirm that what you picked is what you think it is. But you better speak some Japanese if you want to go into lengthy discussions about what would be the best option for you.

Finding these stores is easy.  Your hotel should be able to tell you the nearest one or you can use Google Maps.

A visit to a BIC Camera or Yodobashi Camera store is something that we absolutely recommend.  It is a fun experience during which you can marvel at all the electronic gadgets that are for sale.

But maybe you prefer to compare the various options from the comfort of your hotel room.  This is possible as well. 

You can order your SIM online with Mobal and pick it up directly at one of the many pick-up locations across Japan.

They have a very informative website and offer English support in case you have any additional questions. 

Japan eSIMs

Good news if you have a modern phone that supports embedded SIMs (eSIMs). You no longer have to worry about fiddling with your phone to replace the SIM card. All you have to do is click a link or scan a QR code.

Your SIM can stay in your device and you can switch between your own cellular plan and the Japanese plan. Super convenient and super easy.

Four providers offer eSIMs :

Simcard GEEK

Airalo esims.

Airalo eSIMs are available for a duration of 7 or 30 days and come with a data package ranging between 1 GB and 10 GB.

Frewie offers 2 eSIMS for use in Japan. When ordering a Frewie eSIM through Klook you will get a confirmation mail with a QR code to activate your eSIM. The mail is sent within 24 hours of your purchase.

The Frewie eSIM is a data-roaming SIM that connects to the Docomo network in Japan. It’s not a native Docomo eSIM, you will need to activate data roaming for it to work. Because it uses roaming it can be somewhat slower than the above eSIM options from Simcard GEEK.

One SIM works only in Japan, the other works in Japan & South Korea. Both are data only. The data package varies with the duration of the SIM.

Check prices and more info:

Frewie Japan SIM (5 – 30 days)

Frewie Japan & S-Korea SIM (14 or 30 days)

Japan SIM card for longer stays

For a short stay, you’re best off with a prepaid SIM card but if you’re staying in Japan for several months you could consider an unlimited long-term plan.  

Japanese providers are known to have a lot of red tape.   

A contract with them usually requires a lot of paperwork and a commitment of 2 years. For some, you even need to have a residence visa and/or a Japanese bank account.

Two providers offer long-term SIM plans :

Mobal offers an alternative to the red tape. 

Their long-term plan comes with no minimum duration, no activation, and no termination fee. 

The customer service team speaks English, is super-responsive, and you can easily order the SIM card online.

This is what you will get:

Japanese Phone number : A real Japanese phone number starting with 070, 080 or 090 (Softbank).  A voicemail service is included.

Free calls : All incoming calls and texts are free. Outgoing calls to other Softbank customers (including Mobal customers) are free from 1 AM to 9 PM.

Shipping :  Shipping is always free but not available to all countries.  If shipping is not available to your country you can simply collect your sim for free, at one of the many pick-up locations.  There are locations at the airports and in Tokyo, Osaka, Kyoto and other major cities across Japan.

Shipping of voice+text sims requires that a copy of your ID is sent to Mobal at the time of your order. 

If you don’t want to share these details online you can pick up your package in Japan. All details about shipping and pick-up locations are extensively explained on the website .

Activation : To activate your SIM follow the activation instructions provided with your sim.  During business hours the activation should be processed within 2 hours.

Upgrade data plan : The data+voice SIM has 7GB of data at 4G speed per calendar month.  If you want more data at high speed you upgrade your plan in your online account.

Fair usage policy : If you use more than 7GB in one month your data speed will be reduced to 128kpbs for the remainder of the calendar month.

FAQ About Tourist SIM Cards for Japan

Will your phone work in japan .

Before you buy a SIM you need to be sure that your phone is compatible with Japan’s telecom network. It needs to be able to operate on one of the bands used by the telecom operators in Japan. 

Check the technical specs of your phone to see what bands are supported and see if there’s a match with the bands that the operators are using. We’ve listed all of them in the following section.

Your phone will also need to be unlocked.

If you don’t want to do this manually you can find pages online ( like this page ) where you can select your phone and the network operator to verify if they’re compatible.

Network providers in Japan

Japan has four mobile phone companies that operate their own network.  The three major players are NTT Docomo, Softbank (formerly Vodafone), and Au by KDDI.

A fourth challenger is Rakuten Mobile. Rakuten Mobile used to be a virtual operator but started building out its own network a few years ago. Today it covers about 94% of the population.

All other operators are virtual and use one of the existing networks. The tourist SIM cards we discussed in this article all work on either the Softbank or NTT Docomo network.

The network of NTT Docomo is recognized to be the best in terms of coverage.  Softbank comes in second although they are not far behind. Both these networks cover 99% of Japan (population-based).

These are the bands used by the Japanese operators:

Rakuten Mobile

Pocket WiFi device vs Tourist SIM card

One big perk of using a pocket WiFi device is that you can stay connected without having to mess with your phone.

No need to worry about changing your settings. Just remember to turn off your data connection to avoid those annoying roaming fees. With your SIM card still in the phone, you can stay connected with friends, family, work buddies, and anyone else who has your number just like you’re back at home.

If you want people to be able to contact you anytime, a pocket WiFi device is a great option.

Another advantage of pocket WiFi devices is that they let you connect multiple users at once (usually up to 10!).

Batteries of pocket WiFi devices usually last no more than a day. This is probably the biggest disadvantage. It is one more device that you need to charge on a daily basis.

Interested in Pocket WiFi devices?

See which ones you can rent in Japan . Or if you are going to use this often, you can buy your own device , just like us.

Which size of SIM card do you need

SIM cards have become increasingly smaller over the years. First, we had the standard SIM, then the Micro SIM and nowadays almost all modern phones use a Nano-SIM

Usually, providers use multi-size (3-in-1) SIM cards that are compatible with all phones.  Others only offer 2-in-1 (Micro and Nano) which means they will still be compatible with most current models. 

The technical specs of your phone will show what SIM you need.

In some cases, you will need to specify the requested SIM size with your order.

Free WiFi in Japan

You can easily find free WiFi at many places in Japan. Coffee shops like Starbucks, metro stations in all major cities, and JR train stations offer this convenient service.

Connecting to public WiFi networks was a pain the first time we were in Japan. Not only did we, have to do it over and over again. We also couldn’t get the connection to work for half of the time.

But now there’s a great app called Japan WiFi Auto-Connect that takes care of all the hassle for you. It automatically connects your phone to selected public WiFi hotspots. Only the trusted ones managed by reliable companies or authorities are used by the app for security reasons.

The app worked perfectly for 90% of the time during our last trips. Whenever we walked into a metro station or train station the phone usually connected to the WiFi in a matter of minutes.

The Japan WiFi Auto-Connect app is available for Android and Apple and makes free WiFi much more reliable for foreigners.

Still, I suggest not depending on free WiFi entirely, just like we don’t. As you move away from the big cities, finding reliable Wi-Fi spots becomes harder.

And even in the major cities, I find it super handy to have internet access all the time so I can look up stuff whenever something pops into my head – not just when I stumble upon a hotspot.

It’s a matter of convenience, but SIM cards are so cheap that I think it’s worth it.

Having a Japanese tourist SIM card turned out to be priceless.  With Google Maps we could easily find our way around the cities, we discovered interesting places to eat and we weren’t restricted to touristic restaurants since we could use our mobile phone to translate the menus.

It really helped us to travel deeper and get a better, less touristy experience of Japan.

There’re many different tourist SIM cards so we wrote this post to help you choose the one that suits your needs.  All information is accurate at the time of writing.

We will regularly update this article but if you notice any changes we would appreciate it if you let us know so we can update our post.

1.　What is an eSIM?

eSIM stands for “Embedded SIM,” where the SIM functionality is built directly into the device. More and more recently released smartphones and devices are becoming eSIM compatible.

With an eSIM, unlike a physical SIM card, it is unnecessary to replace or install a SIM card physically, and the entire process from purchase to usage can be done online. You will need to check your smartphone and device to make sure it is compatible with eSIM before purchasing an eSIM. For example, iPhone XS and later models are eSIM compatible (excluding Hong Kong iPhones).

2.　What travelers in Japan need to know about eSIM

Before you buy an eSIM for your Japan trip, there are two things you should know.

How to buy an eSIM

About esim with phone numbers.

We will explain each of these below. If you want to skip to our six recommended eSIM providers, please click here , and you will jump to the second half of this article.

Thinking about buying an eSIM from one of Japan’s major wireless carriers (docomo, SoftBank, and au) for your Japan trip? Unfortunately, the major carriers do not sell short-term eSIM plans for travelers.

So, where can you buy eSIM plans for travelers?

The answer is from telecommunications providers known as MVNOs (Mobile Virtual Network Operators). MVNOs operate using the major carriers’ communications networks. MVNOs create and sell short-term eSIM plans for travelers on behalf of the major carriers. An example of an MVNO is Sakura Mobile, which we will introduce later in this article.

You can visit their website and choose the product and plan that suits your needs. Everything from purchasing to obtaining eSIM information can be done online.

Later , we will introduce the six eSIM providers we recommend when traveling to Japan.

In Japan, eSIM with phone numbers for travel use are rarely sold. Generally, travelers in Japan can only purchase Data-only SIMs, which, as the name suggests, offer only data and do not have a Japanese phone number attached to it.

The reason for the lack of short-term SIMs with Japanese phone numbers is due to Japan’s laws regarding phone numbers and SIMs. Japan has strict identity verification laws and requirements, and Japanese phone numbers are generally provided only to residents living in Japan. Providing phone numbers to non-residents is considered illegal. This is why only data-only SIMs without a Japanese phone number are sold to short-term travelers.

You may find several companies that offer eSIM with Japanese phone numbers, but as explained above, there is a chance that they may be operating illegally. Be aware of these companies and the possibility that an eSIM may not work properly when purchasing an eSIM with a phone number.

Even with Data-only SIMs, you can make calls and chat with others using smartphone apps such as Skype and Whatsapp, making Data-only SIMs also a possible option.

3.　Things to keep in mind when choosing an eSIM

eSIM Activation

Flexibility (extending the usage, cancel & refund policy, adding data, etc.), signal/service coverage, english support.

If you want to skip to our six recommended eSIM providers, please click here , and you will jump to our recommendations.

In most cases, eSIM activation will be done via scanning a QR code. The QR code is usually provided in an email from the provider or, in some cases, installed in an app from the provider. When using a provider’s own app, registering an account with the provider and providing personal information such as your email address, name, etc., is often necessary. On the other hand, if the QR code is sent by email, you will most likely not need to enter any personal information, making it a much easier and smoother process than an application.

With many trips, there are times when things do not go as planned. Some examples include, after purchasing an eSIM, you get sick and cannot go on the trip, a one-week business trip turns into a two-week stay, etc. Also, you end up using more data than you anticipated and run out of available data for your eSIM. Check ahead to see if the provider accommodates instances where there are sudden changes in your trip, canceling the purchase, extending the usage period, or adding more data.

The eSIM providers introduced in this article use Japan’s major carrier networks, which all cover 99% of the Japanese population. This means that, for the most part, anyone, almost anywhere, can get an internet connection. However, be careful when using your phone in rural areas, mountains, or underground. Although your phone may show a signal, the signal may actually be really weak, and the data speeds may be very slow.

Running into connection issues or if you are unsure of settings are things that will make anyone frustrated. The last thing you want is to have to deal with these issues in another language. It may be a safer and less stressful experience if you choose an eSIM provider that offers English customer support. It is also important to know how you can interact with customer support. Below are a few examples of what to consider when thinking about customer support.

• Can they be reached by email, phone, or both?
• Are they available to help on the weekends?
• Do they have an office or stores in Japan?

We recommend you choose a provider who can be reached by both email and phone. You can call them for emergency situations and email them for non-urgent situations. If you are uncomfortable communicating by phone and/or email, choose a provider with an office or store in Japan so you can talk with the staff directly. Also, many eSIM providers are closed on weekends. This can be a problem when you need to contact customer service for assistance. Therefore, it is recommended that you choose a provider whose customer support is available throughout the year, even during the holidays.

So, which provider should you choose?

Did this table help you understand more about which eSIM provider you should choose? Below, we will explain in more detail three companies that we highly recommend for your next trip.

① Sakura Mobile

Sakura Mobile’s eSIM is not the cheapest option on the list, but it does offer flexibility and the ability for up to 200GB of data. In addition, Sakura Mobile can offer data top-up and usage extension for your eSIM if needed. If you are wondering which provider to choose, Sakura Mobile is the clear choice.

Positive points about Sakura Mobile are as follows.

Substantial plans

English customer support throughout the year, large number of positive reviews, japanese provider.

Let us take a closer look at Sakura Mobile.

Sakura Mobile offers a wide range of plans, with data plans ranging from 3 GB to 200 GB and usage periods from 3 to 90 days. You will no doubt be able to find a plan that suits your needs best.

Sakura Mobile’s English Customer Support is available 365 days a year. So, if you have any problems with your eSIM, you can quickly and easily get clear help easily.

There are over 3,000 positive reviews on Sakura Mobile’s website. Compared to the other companies in the above table, it is clear Sakura Mobile is a very highly rated and reliable service.

Sakura Mobile is a Japanese telecommunications provider, so it uses Japan’s largest carrier, NTT docomo’s communication network, providing high-quality communication. In addition to the high-quality network, the service’s proficient and friendly customer service, which can only be found in Japan, is another reason why Sakura Mobile has received high praise from its customers. In addition, since Sakura Mobile has an office and stores in Japan, you can get direct support from the staff.

If you don’t mind a smaller amount of data (for example, 500 MB), Ubigi offers the lowest prices.

However, the number of days of use is limited to 30 days, and there are fewer plan options than other providers. Also, the eSIM installation process requires downloading Ubigi’s own application and registering with the service.

For individuals looking to use the eSIM immediately, it may be better to look for a provider where you can use the eSIM immediately, such as by receiving the QR code for the eSIM directly via email.

③ AIS SIM2Fly

AIS SIM2Fly is one of Thailand’s major telecommunications companies, and its prepaid international SIMs are widely available.

Regarding eSIM plans, only one plan is available: 8-day 6 6GB. If this plan fits your needs, this may be an option worth considering.

5. Physical SIM Card Introduction

If your phone does not support eSIM or you do not want to switch out the eSIM in your phone, fear not! You can always use a physical SIM card for your travel! Read on about how to select the proper travel physical SIM for your trip!

6. Things to know about Japan’s travel physical SIM cards

How to purchase a prepaid SIM card

About prepaid sim cards with phone numbers, reserving online vs. buying at the airport.

We will be explaining each one in detail.

For those who want to know about the 7 recommended SIM card providers, click here to jump to a later section in this article.

You might be thinking that you want to buy a SIM card directly from one of the major Japanese mobile carriers (docomo, au, or SoftBank). However, this is in fact, not possible.

Major carriers provide prepaid SIMs to retailers, and this is how you can get a SIM card from a major carrier.

An example of one of these retailers (also introduced in this article) is Sakura Mobile.

Later , we will be recommending 7 of the best providers to get your SIM card for Japan.

In Japan, there are little to no prepaid SIM cards sold with a phone number. In general, travelers to Japan will only be able to purchase what is called a data-only SIM card.

This is because the ID verification process surrounding getting a phone number is very strict in Japan. It is difficult to sell SIM cards with phone numbers due to these regulations.

There are a few companies that do advertise prepaid SIM cards that include a phone number, but some of them may be operating illegally. If you are looking to purchase one of these SIM cards, you should be aware of the risks.

Even with a data-only SIM card, you will have the ability to use applications like Skype or WhatsApp, so it may be wise to use these when you want to make phone calls.

There are two ways to purchase a SIM card.

• Reserve one online before coming to Japan and pick it up at the airport when you arrive
• Find a retailer selling SIM cards at the airport and buy one after you land in Japan

We recommend the former option, reserving your SIM card online.

There are two reasons for this.

The first is that by reserving online, your SIM card will become cheaper. Retailers with online shops spend less money on operation costs, which makes their products less expensive.

The second is that you can avoid the possibility of SIM cards being sold out.

During the travel season, it is possible that shops selling SIM cards at the airport run out of stock. If you have a prior reservation, you can come to Japan and pick up your product stress-free.

All the providers that we are going to introduce in this article have the option to reserve your SIM card online. It might be wise to make use of it before you make your trip.

7. Things to keep in mind when choosing a physical SIM card

• Connection speed
• Amount of data
• English support
• Airport counters

For those who want to know about the recommended providers, click here to jump to the table.

Let’s go into more detail.

① Connection speed

If you are using your phone during a trip, it’s usually going to be actions like browsing the web, messaging, or using Google MAP. In these cases, 3 to 5Mbps will be enough.

For reference, here is a table that shows the ideal internet speeds you are going to need to complete various activities.

Scroll right for more if on mobile→→

You might be wondering how fast the prepaid SIM cards in Japan can get.

Although connection speed does depend on the SIM card provider, you can expect to experience between 1 and 20Mbps at any given time.

In the later table , you will be able to see the average connection speed for each provider. You might want to choose one with faster speeds for safe measure.

Some companies do not publicly release the connection speeds of their SIM cards. In these cases, we have written “unknown” on the table.

Some other SIM card providers write their connection speeds as numbers like 187Mbps; keep in mind that this is only how fast the connection can get in theory.

If we are talking about actual connection speeds, Japan’s SIM cards will be around 20Mbps maximum. In the comparison table, we have listed the actual speeds so you will know exactly what to expect.

② Amount of data

If you have been researching prepaid SIM cards, you will know that there are many different data plans depending on the company.

Out of all the different types of plans available, we recommend that you purchase an Unlimited Data SIM card.

This is because if you have a plan with a data limit, you face the risk of running out of data partway through your trip.

It would be more than a bit daunting to lose access to Google MAP and Google Translate in a foreign country.

If you are looking to travel worry-free, you should consider getting a prepaid SIM card with unlimited data.

Be aware of the FUP

When using an unlimited data SIM card, you should know that there is something called a FUP.

What is a FUP?

A Fair Usage Policy (FUP) is a system put in place to allow the equal usage of data.

In order to protect the network quality and the fair usage of radio waves, telecommunications companies limit or suspend the internet connection of those who use a large amount of data in a short amount of time.

Although the product is an unlimited SIM in name, you might get stopped by the FUP, and your connection speeds may become slower.

To avoid the FUP, big video downloads, online games, and YouTube binges should be saved for when you can use the WiFi at your hotel.

The SIM card providers that we will introduce to you all use the networks of Japan’s major carriers. With any of these carriers, the coverage rate will be 99% of the populated area of Japan. This means that you should almost always be able to connect to the internet wherever you are.

However, keep in mind that when going through mountains or underground, even the signals of carriers with the best coverage will become weaker.

④ English support

If you are having issues connecting to the internet or can’t figure out the settings to get your SIM card working, you should be prepared by choosing a prepaid SIM provider that offers English customer support to help you out.

It is important to know these details:

• Whether you can get in contact by email, phone, or both
• Whether or not you can contact customer support on the weekends

It might be beneficial to go with a company that can be contacted through both email and phone. You have the option of using the phone during an emergency or sending an email when the situation is not urgent.

Many prepaid SIM providers also do not operate on the weekends. This can be a problem when you need to get ahold of customer service immediately, which is why you may want to choose a company that is open year-round.

⑤ Airport counters

If you are picking up your SIM card from the airport, be sure to check the hours of operation of the airport counters.

This is actually more important than you might think. Depending on the company, some airport counters may not be open for long amounts of time.

A situation in which you go to the airport counter but they aren’t open, and you are unable to pick up your SIM card is not impossible.

When you reserve your SIM card, make sure to check the time you will arrive in Japan and make sure it coincides with the hours of operation of the pickup counter.

8. The best 7 physical SIM cards for travel in Japan

So, which one should I choose?

Does this give you a better image of which SIM card to choose? Below, we will explain in more detail three of the providers that we would most strongly recommend.

Scroll right for more if on mobile →→

Sakura Mobile’s SIM cards are not the cheapest on the list. However, the connection speed is quite fast, ranging from a few to 20Mbps. The data is also unlimited.

Some of the best points of Sakura Mobile include the following:

• Long operation hours of airport pickup counters
• English customer support is available year-round

A large number of positive reviews

Operation hours of the airport counters are long.

Most of the companies in the table above do not have airport pickup counters but require pickup at the airport post office. Depending on the time of your flight, you might miss the hours that the post office is open.

Sakura Mobile, on the other hand, has airport pickup counters with very long operation hours, so you should be able to pick up your SIM card without any issues.

English support is available year-round

The English customer support at Sakura Mobile is available 365 days a year, making it simple and easy to get help when you run into difficulties with your SIM card.

You can also contact customer support through email.

There are over 3,000 positive reviews on Sakura Mobile’s website. Comparing this number to other providers on the table, you can see that Sakura Mobile has a significantly higher number of positive reviews than its competitors.

Additional information Main airport pickup counters

• Narita Airport Terminal 1, 2 / Operation hours: 7:00 am until time of last flight (Every day)

In the following video, the staff of the YouTube channel, “MisoDog TV” explain how to pick up a Sakura Mobile SIM card from the airport.

The pick-up process starts from 0:49.

② HIS Mobile

HIS Mobile is one of the cheapest unlimited SIM card options on the table.

However, one of the downsides to this service is that hotel delivery is the only pickup option available. This means that you will not have access to the internet until you get to your hotel.

Additional Information Main airport counters : None

Visit HIS Mobile here.

Official Website: https://www.his-j.com/

③ GENKI MOBILE

GENKI MOBILE allows you to choose the exact number of days that you want to use your SIM card and you are allowed 1GB per day.

GENKI MOBILE has airport counters stationed at the major airports in Japan. You will be able to get connected to the internet as soon as you land in Japan.

The one downside to GENKI MOBILE is that there is no option to get an unlimited data plan. The maximum amount of data you can use in a day is also 1GB, which means it is possible to use all of it at once.

Additional information Main airport counters :

• Narita Airport Terminal 1, 2 / Operation hours: 6:30 a.m. until time of last flight (Every day)
• Haneda Airport / Operation hours: 24 hours (Every day)

eSIM and physical SIM cards are not the only options for connecting to the internet while traveling in Japan. Pocket WiFi devices, also known as mobile hotspots or portable WiFi routers, are also popular among travelers.

We recommend buying a pocket WiFi if:

• ・You want to use the internet with minimal setup
• ・You want to share data with family and friends who are traveling with you

On the other hand, you should consider purchasing an eSIM or physical SIM card if:

• ・You do not want to carry a pocket WiFi device on your trip

• ・You are not sharing data with other people during your trip

Sakura Mobile offers pocket WiFi devices in addition to eSIM and physical SIM cards. If you are interested, please check the Sakura Mobile travel pocket WiFi website.

I’ll tell you upfront that we use the Holafly eSIM card whenever we travel abroad, and the company even has eSIMs for Japan . We’ve never had a problem using Holafly, and what I like most about these digital cards is that they’re super easy to install and activate.

In this case, I recommend the Japanese SIM cards from SimOptions , which you can order online and have delivered to your home. Just be sure to order it in advance so you can install it before leaving for your trip.

There are other SIM card plans for Japan , so in this guide, I’ll share the best ones, where to buy them, and some tips for finding the most suitable options for your trip.

How do Japanese SIM cards work?

First of all, you should be aware that it’s against the law for tourists to have a phone number from Japan . In other words, you can’t get a SIM card in Japan that includes phone calls.

Fortunately, you can still get travel Internet in Japan thanks to Japanese data SIM cards that allow you to access the Web. In this way, you can make calls and send messages through a mobile app like Messenger, WhatsApp, or Skype.

When you’re choosing a travel SIM for Japan , always check your device’s compatibility and mobile network first. You don’t want to spend money on a card only to find out once you’re in Japan that you can’t use it with your phone.

If you decide to go with the Holafly eSIM for Japan , I recommend checking your device’s compatibility here . For local Japanese SIM cards , you can check this on the retailer’s website or at the storefront.

Japanese SIM card price comparison

I’m going to share the best SIM cards for Japan , but first, here is a brief overview of my top picks. This way, you can quickly compare the most important stats like price, duration, and amount of data.

You’ll see that Holafly offers the best deal for both short-term and long-term trips. Not only is Holafly affordable, but its cards come with unlimited data, so you can enjoy the Internet without worrying about your data usage. The digital SIM card is delivered via email, so you can purchase it before your trip or when you’re already in Japan.

Of course, I know that some people prefer a physical card, so I’ve included several Japanese SIM cards that you can insert directly into your device. The cheapest option is the Rakuten Mobile SIM, which you can buy from a local store in Japan. The downside of getting this card is that you’ll have to locate a store that sells Rakuten Mobile, and the live customer support is in Japanese, so if you have any issues, it could be hard to find a solution.

Personally, I prefer paying a little more for the eSIM from Holafly since the company offers live chat in English. When I need a physical SIM card, I go with SimOptions because I can order it before my trip, install it, and fix any issues I may have prior to landing in Japan.

What is the best SIM card for Japan?

For us, the best SIM card for traveling to Japan is the Holafly eSIM . It arrives by email as soon as we purchase it, so we can buy it whenever we want, plus it offers high-speed unlimited data.

I’ll tell you more about Holafly as well as the other top SIM cards for Japan below so you can make the best choice for your trip and preferences.

1. Holafly eSIM, the best SIM card for Japan with unlimited data

The Holafly eSIM for Japan is a digital SIM, so after you order your card , you’ll get an email with a QR code that you can scan to start accessing the Internet. This is ideal if your phone doesn’t have a dual card slot, or you are already abroad and need a SIM card.

Keep in mind that to scan the QR code, you’ll need to print it out or send it to your travel companion so you can scan it off their device. Also, I recommend checking your phone’s compatibility here before purchasing the international eSIM .

Looking at the Japanese eSIM card plans for Holafly, you’ll notice that each one includes unlimited data. The shorter-term plans are a bit more expensive compared to other local cards, but Holafly is more convenient, and you can snag a discount on your Holafly purchase by using our link.

2. SimOptions, another one of the best SIM cards for Japan

Another one of the best data SIM cards for Japan is the physical one from SimOptions . I like using SimOptions because I can order the SIM card ahead of time and sort out any issues before my trip. It takes 1-3 business days for the card to arrive at your home, so make sure you order it in advance.

Something else I like about using SimOptions is that I don’t have to waste time and go searching for a local SIM card in Japan once I land. Instead, I can connect to the Internet right away and enjoy the rest of my trip. Also, if your device has a dual SIM card slot, you can simply insert the Japanese SIM card without having to remove your regular card.

SimOptions offers customer support by email and live chat in English, and there are different plans to choose from depending on the length of your trip. The plans have varying amounts of data, so here is a breakdown of the prices:

3. SoftBank SIM, another Japanese SIM card with data

The Japanese SIM card from Softbank is a physical SIM from one of the largest and most prominent communications companies in the country. It’s super popular, so you’ll be able to find it at official retailers, shopping malls, and even supermarkets.

Softbank has 400,000 Wi-Fi points throughout Japan, so you can access the network during your trip for free. Keep in mind that, if you use up the first megabyte of your plan, you can only recharge the card for 14 days afterward. I don’t really see the point of this, but it’s something to consider if you’re using data to work remotely.

Another disadvantage of this card is that you only get 500 MB for 31 days. This is equivalent to about two or three days of navigation, so it’s not a lot of mobile data.

Even so, this is a common prepaid SIM card for Japan , so if you decide to get it, you can purchase it online. You’ll have to register on the website by uploading a photo of your passport and providing some basic personal information.

4. IIJmio, an alternative SIM card for Japan

IIJmio is another option to consider if you’re looking for a local Japanese SIM card . It offers basic mobile data plans for 30 days, and while you’ll only get a few gigabytes, it should be enough for occasional Internet use and Google Maps.

One drawback of this card is that once the data is used up, you can’t recharge it. Rather, you’ll have to buy another prepaid Japanese SIM card . On the other hand, IIJmio offers customer support in Japanese and English, and you’ll receive an origami set with instructions as a gift with your purchase.

5. B-mobile, a popular Japanese SIM card for tourists

If you want to buy a Japanese SIM card online , check out B-mobile . With this service, you can order a SIM online, then pick it up once you land at the airport in Japan. B-mobile can even deliver the card to your hotel.

Regarding its mobile data and network, B-mobile has great coverage throughout the country, so it’s quite convenient for traveling tourists. Also, if you need to extend the duration of your plan or add more data, you can do so without having to buy another SIM card.

Overall, this is a flexible option, although you should keep in mind that B-mobile’s SIM card plans for Japan last from 10 to 20 days and don’t offer unlimited data. So, I only recommend B-mobile if you’re traveling short-term and don’t need too much mobile data.

6. Rakuten Mobile, a good Japanese SIM card for travel

Rakuten Mobile is another company with local SIM cards in Japan . Its 30-day plans offer basic, moderate, and unlimited data consumption, so you should find an option that suits you.

In fact, if you plan on spending a month in Japan, Rakuten Mobile is the cheapest Japanese SIM card , particularly for unlimited data. However, the Internet speed isn’t super strong, so that’s something to consider.

You can buy this SIM card in Japanese shopping malls, as well as in many stores and the airport. Activating it is simple since you just have to insert the SIM into your device to connect to the Internet. Your purchase also includes a free Rakuten Mobile email domain (@rakumail.jp).

7. Sakura Mobile, another SIM card in Japan with unlimited data

The last Japanese SIM card that I recommend is the Sakura Mobile card. This local SIM offers some of the cheapest data plans in the country, and it has customer support in English. Overall, it’s a simple and practical option for those looking for a physical SIM card.

Another benefit of Sakura Mobile is that you can order your card online and pick it up at the airport once you land in Japan. If you’re already in the country, you can purchase it at any official Sakura Mobile store. The only potential issues are that you must unlock your device and check its compatibility with the network here .

Where to buy a SIM card for Japan

Depending on which option you choose, you can buy a Japanese SIM card from the U.S. or from Japan. Personally, I prefer buying mine before the trip, so I feel fully prepared, but there is nothing wrong with purchasing a local SIM at a store or airport in Japan.

Again, we always buy the Holafly eSIM in advance through its website . Then, all we have to do is open our email and scan the QR code. When we need a physical SIM, we order it online through SimOptions, allowing 1-3 business days for it to arrive at our home.

Both of these SIM cards for Japan are easy to install and will allow you to travel with total peace of mind, and with support in your language.

Buy a SIM card in Japan upon arrival

Don’t worry if you’re already traveling or have landed in Japan. You can still get an eSIM for Japan with Holafly , although I recommend checking your device’s compatibility here first. There is also the option of getting a local Japanese SIM card , like the ones I mentioned above. You can find them at several stores, supermarkets, train stations, and airports in Japan.

Just remember that if you opt for a local SIM card, you’ll have to locate a store or retailer, which could take some time. Also, depending on the company, customer support may only be available in Japanese.

Most local cards don’t have unlimited data, so if this is something that’s important to you, I highly recommend getting the Holafly eSIM . Holafly’s Japanese plans range from short-term visits to stays as long as 90 days, and they all have unlimited high-speed data. The closest local competitor is Rakuten Mobile, which has a 30-day plan, unlimited data options, and good rates. However, some travelers have told us that after a few days, the Internet speed slows down significantly.

How to activate a Japanese SIM card for travel

Activating an eSIM or SIM card for travel to Japan is simple. With the Holafly eSIM , just scan the QR code in your email. You’ll have to print it out or send it to a travel companion to scan it.

For any physical SIM card in Japan , insert it into your device and activate the data. You’ll automatically receive an auto-configuration text message letting you know it’s ready to use.

Japanese SIM card compatibility and requirements

To wrap up, I’ll reiterate that we love using the Holafly eSIM for Japan or any other trip abroad. If your phone is unlocked and you’ve confirmed here that it’s compatible, I highly recommend it.

Otherwise, there are several other physical SIM cards for travelers that will let you access the Internet in Japan . Hopefully, after comparing the different plans, you’ll find a suitable option that allows you to browse the Web, do Internet searches, and send messages.

If you have any questions about these prepaid SIM cards for Japan , or you’d like to share your experience, please let me know in the comments below. I’d love to hear from you!

Have a great time in Japan!

Hi Ascen Aynat,

How is the connection in rural areas in Japan? I’ll be traveling to Kyushu, Shikoku and Hokkaido and will do quite a bit of hiking and therefore away from urban areas. And in that respect is one option (holafly versus a simcard bought in Japan) better than the other?

Hi Yolanda, The connection in rural Japan is actually pretty good compared to other countries. In my experience, Holafly has always come through with a stable connection, even when we’re hiking or travelling in remote areas.

I’m going to Japan next week and will be there for 10 days. If I get a SIM card for 30 days, can my wife use the same SIM card when she going to Japan in a week after I get back? Or are the cards dedicated to one cell phone when activated? Thanks, Jason

Hi Jason, It depends on the card since some allow data sharing, while others are only for one specific device. Of course, take into account how much data each card includes since if you share it, you’ll run out of data faster. In other words, it could be more cost-effective to purchase separate SIM cards for Japan.

The best SIM cards for travelling to Japan

Make your next Japan trip – whether it’s for business or relaxation – pure pleasure with our guide to the best SIM cards for travelling in Japan.

• Roaming in Japan

Best Japan Travel SIM

• Best Japan Travel eSIM
• Best Japan Roaming SIM

Best SIM option within Japan

Roaming in japan, or 日本で国際ローミング.

Japan has been an important trading partner for Australia for many decades, so many businesspeople will find a need to head to Tokyo on a regular basis. Moreover, it’s also one of the most often-cited desired travel destinations for Australian holidaymakers, whether you’re getting seriously into Japanese cuisine in Osaka or hitting the snow slopes in Hokkaido.

While you don’t have to shift too many time zones – or for Western Australia, any time zones at all – to travel to Japan, one factor you should take into account is how you’re going to manage your mobile connectivity while you’re there. There’s no absolute “best fit” solution that works for everyone, so this article will run through your best choices across standard travel SIMs , travel eSIMs, roaming and local telco choices:

Mobal Short Term SIM

There’s a number of choices in the Japan Travel SIM market that you can order before you leave Australia from brands such as Sakura Mobile and B-Mobile, but if you are going the Travel SIM route it’s hard to overlook Mobal’s short-term tourist SIMs. Starting at ¥4,730 (~$50 AUD, depending on exchange rates) for an unlimited data-only 8 day SIM up to ¥7,920 (~$83) for a full 30 days with unlimited data.

It's worth noting that Japan allows a, shall we say, more “loose” definition of “ unlimited ” than you might think would apply, before you plan to start downloading the entire Netflix back catalogue to your tablet. Most plans are limited to 3GB of data per day, after which data speeds “may” be reduced. For most tourists being prudent 3GB a day is plenty enough, even if you are uploading most of your food and location snaps to Instagram at a frenzied pace.

Mobal’s SIMs work on the Softbank and Docomo networks in Japan with a claimed 99% population coverage, which should cover most places you’re likely to go on business or holiday within Japan.

Best Japan eSIM

As the name suggests, eSIM Japan provides eSIMs as its business model with a range of very competitively priced plans that work primary for short trip travellers, with most plans sold with between 3 to 12 days of validity. You can choose between “unlimited” plans – really they’re just data packs with 384kbps speed capped data once your daily quota is exhausted – or data quota deals with a fixed amount over 7, 15 or 20 days.

One oddity with eSIM Japan is that it also offers the same plans as “city” plans for many popular destinations such as Tokyo, Kyoto, Hiroshima, Osaka and Sapporo. They appear to just be the same plans as the nationwide ones, however, so it’s arguably best to stick with those.

eSIM Japan uses the KDDI network in Japan.

Best Australian deal for Japan roaming

Vodafone $5 roaming.

Vodafone remains the gold standard for global roaming if what you’re after is simplicity. Simply sign up for a qualifying Vodafone postpaid plan, and you can access the inclusions on your plan while travelling throughout Japan for just $5 per day. If you don’t use your phone on a given day, there’s no charge at all, though you also don’t get any of your speed capped data if you’ve already exhausted your monthly quota. In those cases you’ll pay an additional $5 to top up 1GB of data.

Here's a selection of Vodafone plans that support $5/day international roaming

However, as with rival Optus’ $5/day deal or Telstra’s variable price “Day Pass” options, this kind of roaming within Japan can quickly add up if you’re there for a longer holiday or business trip. $5 once doesn’t feel like much, but bear in mind that over a fortnight that’s a spend of some $70 extra on top of your existing bill.

Vodafone isn’t the only telco offering roaming within Japan from your standard Australian SIM, either. Here’s a range of providers who support call, text and data roaming in Japan

BIC Camera SIM

When you land in any Japanese International Airport, you’ll see a number of providers offering local SIM cards and Wi-Fi hotspot devices to tourists. They’re not a terrible deal if you want absolute convenience, but you can typically do a little better by opting for a truly local SIM card.

Only one problem here: As with many countries not all plans are sold to visitors, and your grasp of the Japanese language might be sketchy to non-existent.

Your best and most affordable bet in this case is to head to a BIC Camera store. The vast majority of Australian vistors will be landing in Tokyo, and there’s no shortage of BIC Camera stores throughout Tokyo, but also in basically every other major city as well.

Why BIC Camera? Partly the ubiquity of its stores (also fun to browse for everything from electronics to bicycles, luggage to anime figures and plenty more besides), but also because most BIC Camera stores are quite large and you’re more likely to find a staff member or two with enough English language savvy to meet your needs for a SIM when you’re there. BIC also sell other SIM cards so it’s worth checking if there’s a good seasonal deal while you’re there.

If your current handset doesn’t support eSIM, then sadly, the answer is no. There’s no magic bolt-on or software app that can add the needed virtual SIM circuitry to a phone that doesn’t support eSIM out of the box.

If your phone does support eSIMs, then it’s quite simple to set up your eSIM before you travel. We’ve got a handy guide to setting up eSIMs for Apple iPhone and Android here .

It wasn’t that long ago that the answer to that question would have been no, with public WiFi very thin on the ground even within hotel accommodation.

The Tokyo Olympics didn’t go to plan, but one factor that was planned in was a wider pitch to tourists, and this included a huge expansion of available free WiFi options. Having travelled extensively through Japan over many years, I can say that it’s better than it used to be – but it’s hardly simple, and can be a tad baffling if you don’t have a decent grasp of written Japanese for signing into web portals and such.

You could get by with a little patience and pre-planning if your accommodation offers WiFi, though. There it’s more likely to support simple sign-ins, and if you offload maps, podcasts and video content from there to keep you going, and then use the WiFi in coffee shops and some shopping centres, you might be able to do so for no additional cost. Compared to, say, travelling Europe or the USA, however, it’s still not as common or convenient, and having a decent VPN installed is a must.

Hiroshima-style Okonomiyaka, preferably prepared for you on the spot in Okonomimura in Hiroshima . Your waist might not forgive you… but it’s worth it.

Staying Connected in Japan is Easier Than Ever

June 22, 2023 by Robert Schrader Leave a Comment

Would you believe that when I first visited Japan in 2014, it wasn’t even possible for travelers to buy SIM cards? Well, it was, but not for foreign tourists.

That changed quickly as the Olympics drew closer, and as inbound tourism became more and more important to Japan’s bottom line. By the time Japan closed its borders in early 2020 (which, sadly, ended up dooming the Tokyo Games), it was as easy to buy a SIM there as it was in any other country in the world.

Now, there’s an even more convenient option for foreign tourists visiting Japan: A Japan eSIM. Order your Japan eSIM now , or continue reading to learn more about why this new technology is such a huge deal for travelers to Japan.

eSIMs Have Changed the Game for Travelers to Japan

In one way, I’m surprised that there’s now an eSIM for Japan. As I explained in the intro to this post, Japan was extremely slow to allow foreign tourists to buy SIM cards at all. Given that I only began using eSIMs myself in 2021, I didn’t think that within just two years, Japanese eSIMs would be readily available for purchase. So there’s that aspect to consider.

Beyond the historical context, there’s also the profound reality: You can now install something on your phone that allows you to be instantly connected the moment your plane lands in Japan. This not only saves you from having to buy or pick up a physical SIM card at Haneda or Narita airports , but allows you to start planning out how you’ll get to your hotel and enjoy meals and sightseeing as soon as you arrive, instead of having to wait until you’re already on the train.

How to Use a Japan Travel eSIM

Make sure your device is esim compatible.

While the majority of modern smartphones accept eSIMs, not all do. As a general rule, iPhones and Samsung devices released in 2020 and later are eSIM-compatible, while that year might be slightly later for non-premium phones. Still aren’t sure if you can use an eSIM with your handset? Here’s a link where you can easily check your device’s compatibility .

Choose a Japan eSIM

When it comes to eSIM in Japan, there are many options, but almost all of them function similarly. Indeed, when you select your Japan eSIM , the real decision is not which company you use (since they all leverage the same Japanese cell networks), but your data plan: How much data and for how long? For example, you could choose a plan with 5G per day, or 30 GB spread out over 30 days.

Install your Japan eSIM

Once you purchase your eSIM, you’ll typically receive a QR code (and also, some backup information that you can manually input if there’s an issue with the QR). When you can the QR code (or input the information), the eSIM will install in the appropriate area of your phone. Note that this is only one step of being able to use an eSIM in Japan—the second one is just as important.

Land in Japan and activate

Indeed, the most essential aspect of using an eSIM for Japan travel is being in Japan. After all, if you activate your Japan eSIM (on most devices, this means setting it to “Primary”) and you’re outside of Japan, your device will lose its cellular connection. To put it another way, as excited as you might be to buy your Japan SIM, don’t waste time trying to use it in your home country—it won’t be possible.

Stay connected as you explore

Once you’ve installed and activated your eSIM upon landing in Japan, there’s just one thing to do: Put it to use! Japan is a country where you’ll always want more information on the things you’re experiencing, so Google will practically be an extension of your body. (To say nothing of Google Translate: The patch for Japanese within this app is extremely powerful and versatile.)

Why Doesn’t My eSIM Work?

While eSIM is now a tested and reliable technology, it doesn’t work on all devices. This is especially the case for older iPhone and Samsung models released before 2020, and for even some newer models of non-premium cellphone brands. If you try to install an eSIM and aren’t able to do so, chances are very good that your device is simply not eSIM compatible.

On the other hand, there are some situations where it’s just the specific Japan eSIM that doesn’t work. This could be due to the SIM itself (if it’s worth buying, you’ll be able to use a compatibility checker before you complete your purchase). Alternatively, it could be that you’ve designated another SIM (be it physical or a secondary eSIM) as your phone’s primary SIM card or, perhaps more fundamentally, that you haven’t yet arrived in Japan (generally speaking, your Japan eSIM won’t work outside of Japan).

Other FAQ About Travel eSIM in Japan

Which is the best esim for japan 2023.

While I’ve personally had good luck with the Japan eSIMs sold by the inbound corporation, the reality is that most eSIMs sold in a particular country are priced similarly and enjoy similar functionality. In Japan, you can generally expect to have similar coverage and speeds, no matter which eSIM you end up using.

How do I add an eSIM for Japan?

Installing an eSIM for Japan is extremely easy. While it varies slightly depending upon which device you have, it’s usually a matter of scanning a QR code, which will input the eSIM’s settings into the appropriate area of your phone’s backend. The key thing to understand is that your eSIM won’t work until you touch down in Japan.

Does iPhone eSIM work in Japan?

If you have an eSIM-compatible iPhone, you will definitely be able to use it in Japan. Just make sure that you’ve purchased and activated your eSIM before landing in Japan, and that you’ve set your eSIM as your phone’s primary SIM card.

The Bottom Line

Choosing the best eSIM for Japan travel is one of the many ways to stay connected as a foreign visitor to Japan these days—traditional, physical Japanese SIM cards are no longer the only option. This is a far cry from how it was just a decade ago, when non-resident foreigners were only able to “rent” SIM cards and, if they didn’t rent mobile WiFi units, mostly had to subsist off what was then substandard WiFi. While the Tokyo Olympics that set these changes into motion ended up being canceled, the reality is that it’s now easier than ever to stay connected as you explore Japan. If you haven’t already, buy your Japan eSIM today , so you can be connected the moment your plane lands in Tokyo.

Your Prepaid SIM Card Options for Travel in Japan

You land in Tokyo and ride the train into the big city. Maybe you stand in the middle of Shibuya’s Scramble Crossing , delaying traffic while you take a selfie. Or you hit up a restaurant, pointing at a random photo on the menu and hoping the waiter gets what you’re trying to order. And when it arrives, the first thing you think is, “I need to post this to make my friends envious.” Here’s the lowdown on getting a Japan SIM for your visit, for your data and voice communication needs.

Note: This article is about SIMs for a short stay in Japan. If you’re planning on living in Japan or you’re here for an extended period of time, see our article on  Japan SIM contracts .

Short-term Japan SIM options for tourists

I’m here for a week or two and just need to update my status every dayyyyy.

That’s fine; if you order your SIM in advance, you can get online the minute you pick it up at the airport (all companies provide some form of airport pick-up). This isn’t an exhaustive list; just our top picks of prepaid Japan SIM cards. Keep in mind that some of them can be recharged with extra data.

More about the providers

Mobal: the only option with data + voice.

With the Mobal voice + data SIM , when your 7GB is up, data is still available at slower speeds. Top-ups can be purchased. 60-, 90-day and long-term packages also possible. If you’re traveling from China , you have access to a range of other prepaid packages . Free shipping to many countries, or pick-up at Narita or Haneda Airport, as well as Fukuoka, Kansai, Nagoya and Sendai airports and downtown Tokyo and Osaka. Similarly to all voice-calling products, the voice + data SIM carries a ¥ 2,970 initial fee, which is included. On the data-only SIM, speeds may be temporarily reduced if more than 3GB is used in a day.

Simcard Geek

Simcard Geek has other SIM plans available. There is free shipping to many countries, or pick-up at the post office at Narita Airport or at other major airports in Japan. Fair usage applies, and speeds may be temporarily reduced if more than 3GB is used in a day.

Sakura Mobile

Sakura Mobile SIM cards come pre-activated, so you simply plug and play. Longer-term SIM deals also available. Fair usage applies to data.

Called Japan Travel SIMs, IIJmio SIMs are available at airports and electronic stores countrywide. Prices are approximate, and the maximum (theoretical) speed is 788Mbps. SIMs can be recharged with extra data. Chinese language call center support is available.

Runs on the NTT DoCoMo network. SIM cards can be recharged with extra data. Delivery costs ¥ 370 to Japan airport post office, or ¥ 520 to a hotel/other accommodation. You can buy them at electronics stores and Aeon, too. SIM cards must be returned after use.

Voice + data vs. data-only travel SIMs

While data-only SIMs are often the default for travel these days, there are strong arguments for getting a SIM that allows you to make and receive calls and send/receive texts, from an actual Japanese phone number.

Making voice calls with a Japan travel SIM

With the exception of Mobal’s voice + data SIM , Japan’s SIM cards for short-term travelers are data-only, meaning you can’t call or text, or even receive phone calls. A partial workaround is to make VoIP calls through an app like Facebook Messenger, Skype, LINE or WhatsApp, but, as a group of tourists found out after driving their rental car into a ditch, this can be unreliable — we had to lend them our phone to call for roadside assistance.

Apps that require a Japanese phone number

Emergencies aside, you’ll need a Japanese phone number in order to use a number of apps locally — even if they can be downloaded outside of Japan. These include the following:

• Mobile Suica
• Yahoo! Japan

If you’re planning on using any of the above on your Japan trip, you’ll want to make sure you have ordered a voice + data SIM .

Buying a SIM card in Tokyo (or elsewhere in Japan)

Oops. Just ignored everything you said and went straight into town. Sorry.

No worries. Just look for a BIC Camera store (link in Japanese, but Shibuya, Shinjuku and Ikebukuro have quite a few) or Yodobashi Camera  (also in Japanese) and grab yourself whatever Japan SIM card seems like the best deal. Bic SIM cards are fairly popular, we hear. For more information, see our guide on where to buy a SIM card in Tokyo .

Once you’re in the shop, you can say to the staff: シムカードを探しています。私に合うのはどれですか？ Shimu kādo wo sagashiteimasu. Watashi ni au no wa dore desu ka? That translates to “I’m looking for a SIM card. Which one would be best for me?” Many stores will have English-speaking staff, to make things easier.

Japan SIM cards for tourists: Frequently asked questions

Got questions about Japan travel SIM cards? We have answers.

Which tourist SIM cards can I buy in Japan?

Mobal SIMs and Rakuten prepaid SIMs are among those you can order online when you are already in Japan. Other options include BIC Camera SIMs and IIjmio’s Japan Travel SIM, which you can buy at the airport. For more info, see our guide to buying a SIM card after arrival — while the focus is on Tokyo, it applies to all of Japan.

Where can I buy a Japan SIM card in Singapore, Malaysia, Hong Kong or The Philippines?

If you are traveling from one of the above areas, you can order a SIM card online and have it delivered before you leave for Japan, or—depending on the provider—pick it up at your local airport or landmark. For example, Mobal SIM cards can be collected at Singapore’s Japan Rail Cafe or the Nikkei Education Center in Hong Kong. There may be other options for your region.

How do I activate a Japan SIM card?

The exact steps depend on the provider, but generally it’s a matter of inserting the SIM into your phone and following the instructions provided. It doesn’t take long, and you should be able to start using it straight away.

Can I use an eSIM in Japan?

If you have a newer phone or tablet, you might be able to use a software-based eSIM card (instead of a physical SIM card) for your trip to Japan. Read more about eSIMs in Japan .

Where are the big companies like SoftBank, Docomo and AU?

As in most countries, there are network providers with their own retail brands, and smaller companies that operate on the networks of the big players like Docomo. You can get travel SIMs from the big players if you go into their stores, or order online from e.g. Amazon, but the smaller players usually provide the best value.

Alternatives to SIM cards for tourists in Japan

Wait a minute, this is TokyoCHEAPo, not TokyoEXPENSIVEo, you want me to pay actual money for a service? 

Not at all! You can be super cheap about data and use free wifi from teH giAnt Corporations. First up,  a coffee chain that I understand is quite popular with the kids, has free wifi, providing you register at the link above. Then, just pop into a store and away you go!

Sign up? That’s WAY too much work. 

OK, well, Apple happens to give out free wifi at various store locations with no login needed. And if there’s not one of those near you, the good ol’ Tokyo Metro provides free wifi too. AND if your home internet provider is part of the Fon network, you can use your own home internet login and passcode on Fon hotspots, which are practically everywhere in Tokyo. That’s not taking into account the myriad cafes and restaurants which also offer free wifi .

OK, calmed down now. Carry on.

It is worth pointing out a few other alternative solutions, too.

Renting a travel wifi router

First up, if you have more than one device that requires the net, or a few of you are traveling together, you may want to consider a portable wifi device from a rental provider like Ninja Wifi , who give our readers a 10% discount.
