How much does the Japan eSIM cost?

How do I activate my Japan eSIM?
Scan the QR code in your phone settings (Cellular/Mobile → Add eSIM) or tap Install in the eSIM TopUp app. Install on Wi-Fi before your trip; it activates when you arrive in Japan.

It works on any eSIM-compatible, carrier-unlocked phone — iPhone XS and newer, Google Pixel 3 and newer, and recent Samsung Galaxy models.
