Arrival procedures
How do I get a SIM card and a Japanese phone number?
For internet access on arrival, a travel eSIM or prepaid data SIM is often the quickest option. If you also need a Japanese phone number for calls and text messages, choose a voice plan and check the provider's identity-verification requirements.
Depending on the provider, you may need a residence card with your current address, a passport, a payment card or Japanese bank account. Some services accept overseas cards and offer airport pickup. Compare the monthly fee, activation charge, data allowance, call costs and cancellation terms. Check that your phone is unlocked and supports the SIM or eSIM you choose.
What may vary
Online identity checks may not support every residence-card format, so a shop visit or another verification method may be needed. Rules and prices change: use the provider's current application page, especially for cards issued from 14 June 2026. Keep access to your home number if you still need it for bank verification codes.
