What You Should Know About Japan eSIM

You can buy and install your Japan eSIM at home before your trip. Once you land in Japan, just activate it and you’re online right away. It really doesn’t get any easier.
When choosing a travel eSIM for Japan, you usually have two options: plans with unlimited data for a fixed number of days or plans where you pick a set amount of GB in advance.
Most providers offering eSIMs for Japan include both options, so you can decide what fits your travel style best.
Our Recommendation: Saily as an eSIM for Japan
We recommend Saily as your eSIM for Japan.
Saily’s eSIMs for Japan are very affordable and extremely easy to manage via the app (iOS I Android). The eSIM activates automatically once you arrive in Japan, so there’s no need to hunt for airport Wi-Fi first.
With Saily, you can choose between a fixed amount of data or unlimited data, making it a very flexible travel eSIM for Japan.
For a 2-3 week trip, we recommend 20 GB. That’s plenty if you mainly use your data for Google Maps, navigating public transport, checking messages, and posting the occasional photo. On our own two week trip, we used around 15 GB per person.
If 20 GB isn’t enough, you can easily add more data directly in the app. You can also track your usage and see how long your plan is valid at any time.

Our Personal Experience with Japan eSIMs from Saily
We used a Saily eSIM on our trip through Japan and were very happy with it. We’ve relied on Saily many times before and have always had great experiences.
Over 16 days, we used just under 15 GB per person. We initially bought 10 GB before the trip and then added another 5 GB along the way.
In hindsight, it would have been cheaper to book 20 GB right away. There’s no 15 GB option anyway, and with 20 GB you don’t have to worry about running out of data.
Our Conclusion on the Japan eSIM
For most travelers, we clearly recommend a Japan eSIM from Saily. It’s the best eSIM for Japan if you’re planning a classic round trip.
You get great value for money, an easy to use app, and a wide choice between fixed data packages and unlimited data.
We recommend choosing 20 GB. That’s more than enough for a 2 to 3 week trip through Japan.
