Getting connected in Tokyo starts with a real phone number

Tokyo becomes easier once your phone works like a local phone. A real Japanese number can help with reservations, SMS verification, deliveries, apartment setup, banks, and everyday admin.

The guide recommends Rakuten Mobile as the broad default because it balances a real number, data, eSIM support, shop support, and easier access for newcomers.

Rakuten is not always the absolute cheapest plan. BIC SIM and IIJmio can be better value for residents who can handle more Japanese signup friction. The Tokyo Loop recommendation is about the first reliable choice, not the most optimized bill.
