How a RoamFinch plan works
Country plans for Japan. A package covers Japan only when the supplier lists JP.
Confirm eSIM support and that the phone is unlocked. Those are two different questions. Open the destination and read the countries, data allowance, and validity. The price shown is the supplier's suggested retail price. A successful payment places one plan. The QR code or activation string arrives after the supplier accepts the order. Do not delete the eSIM until the trip is over.
Tokyo, Osaka, Kyoto, Hiroshima, Sapporo, Okinawa, Narita, Haneda
These names find Japan. They are not separate plans. A package covers them only when the supplier lists JP.
NTT docomo, Rakuten Mobile, KDDI/au, SoftBank
Operator names come from the supplier packages (3G/4G/5G). They are not a promise of speed at one address.
Plan the stops.
Add cities or countries. The checker looks for one package whose country list includes every stop. Check the route
Questions before you buy
Does a city name mean a separate Japan eSIM?
No. City and region names only find Japan. The package covers the countries it lists, not one neighborhood.
When does a package include Japan?
Only when the supplier country list includes JP. RoamFinch does not add coverage the package omits.
What should I check before ordering a Japan eSIM?
Confirm the phone shows Add eSIM, confirm the carrier has unlocked it, and read whether validity starts at installation or at the first connection abroad.
How do I check a route that includes Japan?
List every stop in the route checker. Japan counts only when the package lists JP. Install on Wi-Fi, then turn the line on after you arrive.
How many Japan plans are listed?
55 Japan eSIM plans, 100 MB to 999 GB, valid 1 to 180 days. Coverage is the supplier country list. Check the phone before you order.
