Getting an eSIM for Japan is one of the easiest and most cost-effective ways to stay connected while travelling. An eSIM allows you to access local mobile data without a physical SIM card, helping you avoid expensive roaming charges from your UK provider. <\/p>

Here, we look at the best eSIMs for travel to Japan, including Revolut<\/a>, which offers a sign-up bonus of \u00a320.<\/p>

How to get an eSIM for Japan<\/h3>

Buying an eSIM for Japan works much like buying a physical SIM \u2013 you can usually purchase it online or via a provider\u2019s app. The difference is that the process is generally quicker, provided you\u2019ve confirmed your device supports eSIM. <\/p>

If you organise everything in advance, you can start using your data the moment you arrive in Japan. However, you\u2019ll need to think carefully about how much data you\u2019re likely to use on your trip as different providers offer different data plans, so it pays to have an idea before you start your research. <\/p>

Local eSIM providers in Japan<\/h3>

If you\u2019d rather buy your eSIM from a provider based in Japan instead of a global eSIM provider, our 4 top picks are as follows:<\/p>

\"Sakura <\/div>

Sakura Mobile<\/h4>

Sakura Mobile operates under the NTT Docomo and KDDI (au) networks. Its Travel eSIM is designed for visitors to Japan who are staying for up to 90 days. It offers unlimited data, but note that as this is a data-only plan, it won\u2019t come with a phone number. However, you can still use apps like WhatsApp and Zoom to make calls and send messages over the internet using the data connection.<\/p><\/div><\/div>

\"Japan <\/div>

Japan Wireless<\/h4>

Japan Wireless offers travel-related services to those visiting Japan, including eSIMs. Select how many days cover you require (up to 30 days) and then choose from a 5G unlimited plan, a 4G unlimited plan or a fixed plan offering between 1GB and 50GB of data, depending on how much you need. Again, these are data-only plans and use the NTT Docomo and KDDI (au) networks.<\/p><\/div>

\"eSIM <\/div>

eSIM Japan<\/h4>

eSIM Japan offers a more comprehensive range of eSIMs for travellers, and they are all powered by KDDI or SoftBank. Its 5G unlimited max plan offers unlimited data for 3 to 31 days with maximum speed, while its unlimited data plan comes with unlimited data for 3 to 30 days. You can also select plans with data ranging from 3GB to 50GB for 7 to 30 days, as well as a variety of multi-country plans if you\u2019re also planning to visit Korea, China, Taiwan, Australia and so on.<\/p><\/div><\/div>

\"NipponSIM <\/div>

NipponSIM<\/h4>

NipponSIM offers an unlimited prepaid data-only eSIM for use in Japan, for 4, 7, 10 or 15 days. It offers 4G and 5G coverage and uses the KDDI mobile network.<\/p><\/div><\/div>

How can I buy an eSIM in person?<\/h3>

If you don\u2019t want to buy an eSIM online, it\u2019s possible to buy them in person, but your options will be more limited. Your best bet is to keep an eye out for carrier kiosks at the airport when you arrive, as you may be able to buy a prepaid eSIM there. <\/p>

Alternatively, you might be able to find eSIMs at large retailers such as Bic Camera and Yodobashi Camera, or in convenience stores like 7-Eleven. But there are no guarantees and your safest option is to buy one online.<\/p>

Can I use an eSIM with my phone?<\/h3>

Before you buy an eSIM, make sure you check whether your mobile device is compatible. If you have a modern smartphone, such an iPhone, Samsung Galaxy or Google Pixel model, it should support eSIMs. Older handsets, on the other hand, are unlikely to. <\/p>

Bottom line<\/h3>

Buying an eSIM is one of the easiest and most cost-effective ways to stay connected while travelling in Japan. It allows you to access local mobile networks without racking up the high roaming fees your UK provider<\/a> would charge. However, before buying, take the time to compare plans, thinking about how much data you\u2019ll need while you\u2019re away, and pick the option that offers the best value. <\/p>
