Japan Experience

Japan Experience is a Tokyo-based eSIM provider that uses IIJ's existing relationship with NTT Docomo to deliver reliable 4G connectivity throughout Japan. The service supports devices with Band 1 and Band 3 compatibility, which covers most modern smartphones sold internationally.

Activation codes remain valid for four months after purchase, giving travelers flexibility in timing their trips. Best suited for longer stays or multiple visits within a calendar year, Japan Experience appeals to people who want local infrastructure backing their connection without relying on a multinational aggregator.
