IIJmio: what it costs, and who it accepts

Checked / SIM Navi team

IIJmio's plans for people living in Japan, what it takes to sign up, and the real monthly cost including the setup fee. Everything here comes from IIJmio's own official pages.

IIJmio states on its official pages that it accepts foreign residents, and a residence card is accepted as ID; its lowest real monthly cost is ¥1,701 at 3GB a month (12-month cost including setup fees) (checked October 6, 2026). Whether your application is approved is the carrier's decision.

Who IIJmio suits

A good fit if
  • You hold a residence card — this carrier states officially that it accepts residents.
  • You want to use the residence card itself as ID.
Look elsewhere if
  • You hold a newer-type residence card — A second-generation residence card or special permanent resident certificate issued on or after June 14, 2026 cannot be used for online sign-up yet (IC chip reading plus a face photo); IIJmio says support is planned for this winter. The My Number card-integrated types (Specified Residence Card, Specified Special Permanent Resident Certificate) work online through the JPKI method.
  • You have no Japanese credit card — this carrier states a credit card is required.
  • You need English support — see the language note at the top of this page.
  • You may leave within the first month — a minimum term is stated: it runs to the end of the month your service starts.
