📋Step-by-Step Guide

Choose your carrier type

Major carriers (docomo, au, SoftBank) offer full service but require longer residence history. MVNOs (IIJmio, OCN Mobile, etc.) and Rakuten Mobile are more foreigner-friendly.

Get an eSIM for immediate connectivity

Before or right after arrival, purchase a data eSIM (SoftBank, IIJmio, etc.) for immediate internet access. Activate it before your flight.

💡 小贴士: eSIMs from Rakuten Mobile or IIJmio can be activated with just your residence card after arrival.

Prepare your documents

You'll need your residence card (在留カード), passport, a Japanese bank account or credit card for payment, and your My Number (some carriers).

Sign up online or visit a store

Rakuten Mobile and IIJmio have English support and accept foreigners. Visit a carrier store or apply online. Online is usually faster.

Port your SIM number (optional)

If you want to keep your phone number, request an MNP (Mobile Number Portability) transfer code from your current carrier.
