A city break or a longer rail itinerary
For Tokyo and Kyoto, start with the days and total data you need. For a longer route, include travel days and check coverage around smaller stops. Download maps and entertainment before departure to make your allowance last longer.
Fixed data, unlimited and hotspot
Compare the total price for your whole stay. Unlimited plans may have speed or hotspot conditions; an unconfirmed allowance is not a promise of unrestricted tethering. If you work on a laptop, use the confirmed-hotspot filter and read the plan’s details.
Adding South Korea or another destination
A Japan-only plan cannot cover your next country. Use the trip planner to compare separate plans with a regional bundle. Check the explicit country list, shared data and the date on which the regional allowance starts.
Check before buying
Check that your exact device supports eSIM and is carrier-unlocked. Match validity to your whole stay. Check local networks, hotspot, when the plan starts and the final price with the provider.
