Who Y!mobile suits

A good fit if

  • You have no Japanese credit card (the official pages list bank transfer and debit card).
  • Support is available in Japanese, English.
Look elsewhere if
  • You hold a newer-type residence card — A residence card or special permanent resident certificate issued on or after June 14, 2026 cannot be verified in the app. Use verification by the delivery person.
  • A cancellation fee is stated: ¥1,100 — only if you cancel within 12 months of joining on or after July 1, 2026 (¥858 on Simple 3 S/M, ¥1,100 on Simple 3 L).
