Japan SIM & eSIM Finder 2026

Which Japanese SIM or eSIM actually fits your situation? Answer the eight questions below — the finder filters by the things that are hard to undo (real 070/080/090 number, passport-only signup, where you live, SMS verification) and ranks what's left by fit and price. Recommendations come from a maintained, dated provider dataset — not ads.

Your Situation

Do you need a real Japanese phone number?
Do you have a residence card (在留カード)?
What best describes your situation?

One provider sells only to people whose home is outside Japan, so "visiting" and "moving here" are different answers even though both mean you do not live here yet. Moving for work or study makes you a resident within days of arriving.

Will you need SMS verification?
SIM format
Monthly data
How long will you be in Japan?

Answering “short” also brings in prepaid travel eSIMs. Those are data-only packs that expire — no Japanese phone number, so they cannot be used to open a bank account, sign a lease, or receive SMS verification codes. They are labelled “Travel eSIM” in the results.

Do you need English signup & support?
