About this comparison
- Plans and prices were read from the Airalo and Yesim Japan pages on 11 November 2026. Providers change prices often, so confirm on their page before you buy.
- Airalo's page listed its Japan plans in yen and showed only unlimited plans. Yesim's page listed fixed-data plans in US dollars; its unlimited plans were not shown in the page we read and are not included.
- "Unlimited" plans can be slowed after heavy use under the network's fair usage policy. Check the provider's terms for the limit.
- These are data-only plans. They do not include a Japanese phone number.
- Your phone must support eSIM and be carrier-unlocked.
- This page compares two providers so far. More will be added as their plans are checked.
