What you should know about Japan eSIMs
You can buy and install your eSIM before you even leave home. After landing, just activate it and you’re online. Perfect for your trip to Japan.
You can choose between eSIMs with unlimited data for a set number of days and eSIMs where you select a specific amount of GB upfront.

Our recommendation: Saily as an eSIM for Japan
We recommend Saily as our top Japan eSIM pick.
Saily’s eSIMs for Japan are seriously affordable and super easy to install in advance via the app (iOS I Android). In Japan, the eSIM activates automatically. You don’t have to hunt for Wi-Fi at the airport.
With Saily, you can choose between a specific number of GB and unlimited data.
For a 2- to 3-week road trip through Japan, we recommend 20 GB. That’s plenty if you’re using your data for Google Maps to navigate public transportation in Japan and for messaging or occasional social media. On our two-week trip, we used about 15 GB per person.
If 20 GB isn’t enough, you can easily top up your data right in the app — no hassle at all. The app also lets you keep an eye on your usage and remaining time at a glance.

Our personal experience with Japan eSIMs from Saily
We used Saily eSIMs on our trip through Japan and were really happy with them. We’ve used Saily on many trips and have honestly never had a bad experience.
Over 16 days, we used just under 15 GB per person. We bought 10 GB before our trip and had to top up with another 5 GB.
That said, it’s cheaper to just buy 20 GB upfront. There’s no 15 GB option anyway, and with 20 GB you won’t have to think twice about running out of data.
Our verdict on the Japan eSIM
We recommend a Saily eSIM for your trip to Japan. It’s perfect for a classic road trip.
It has the lowest price, is super user-friendly, and gives you a wide selection of GB amounts or unlimited data.
Go with 20 GB. That’s more than enough for a two- to three-week trip.
