About Japan eSIM plans
Japan is one of the destinations where the breakout location changes what you can do. IIJ plans break out in Japan, so Japanese sites and services see a domestic address; TSimTech routes via Singapore and RoamVault via Hong Kong. The trade-off is that no IIJ plan can be topped up, so choose the size for the whole stay up front.
Which plan suits your trip
- A few days in Tokyo or Osaka: Japan Short Trip (3 GB, 5 days) or an Airalo Unlimited 3 or 5 Day plan.
- Two-week holiday: 10 GB on a 15 or 30 day plan.
- Long stay or working: IIJ offers 35 GB for 60 days and 60 GB for 90 days.
The China Korea Japan Short Trip plan and our Asia regional plans cover Japan alongside its neighbours.
