Japan SIM & eSIM Finder 2026

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