Japan eSIM: Plans, Prices and Data Guide

Japan is easy to travel in and surprisingly easy to get wrong on data. Station Wi-Fi is patchy inside trains, maps and translation apps run constantly, and a wrong turn costs you time you do not get back.
We keep four Japan plans — short trip, standard trip, long stay, and a 90-day option for people working from Japan. Here is what each one is really for.
Pick by trip length
3 days: 9 GB over 3 days, $12.15 — enough for maps, translation and photos.
1–2 weeks: 15 GB over 15 days, $21.12. For a one-week trip this actually costs less than the 7-day plan, so take it.
A month or a season: 50 GB over 90 days, $53.94.

How to choose
- 9 GB / 3 days — The short-break plan. Three days of city travel with maps, messaging and a few hundred photos sits comfortably inside 9 GB.
- 15 GB / 15 days — The best-value option for most trips, including one-week trips. It costs less than the 7-day plan and gives you a longer validity — there is no reason to pay more for less time.
- 50 GB / 90 days — For a working stay or a long rail trip where you tether a laptop. Validity runs continuously from first connection, so buy it when you are close to departure rather than months ahead.
Before you buy
- Install before departure on Wi-Fi — the QR code arrives by email within minutes of ordering.

- Enable data roaming on the eSIM line, otherwise it will not attach to a Japanese network.
