Per-day and per-GB figures are approximate, converted to US dollars at the European Central Bank rate of 19 Oct 2026. Prices are in the currency each provider’s site showed us, so you may see a different currency. You pay the provider’s checkout price. Per GB is left blank for unlimited and daily-allowance plans.

How to read this table
- Network is the Japanese carrier the plan runs on. docomo, au and SoftBank all cover the cities well. Differences show up in the countryside and mountains.
- Per day and per GB are converted to US dollars at a fixed rate so plans in yen and dollars can be compared. You pay the provider’s own price.
- Phone number means a Japanese number that can make and receive calls or SMS. Most travel eSIMs are data only.
- Hotspot means you can share the connection with a laptop or another phone.
