📱 How to Get a SIM Card in Japan as a Foreign Resident
Getting a mobile phone is one of the first things you need to do after arriving in Japan. Here is everything you need to know about choosing and activating a SIM card.
What You Need
To sign up for a SIM card in Japan, you typically need: your Residence Card (在留カード), a bank account or credit card for payment, and in some cases your My Number Card. Most carriers now accept online applications.
Budget SIM vs Major Carriers
Major carriers (docomo, au, SoftBank) are expensive (¥5,000~¥10,000/month). Budget SIMs (格安SIM) like Rakuten Mobile, LINEMO, and GTN Mobile offer plans from ¥990/month with no minimum contract period — perfect for foreign residents.
Foreign-Friendly Options
GTN Mobile is specifically designed for foreign residents with multilingual support in Vietnamese, Chinese, Nepali, and Indonesian. Rakuten Mobile and LINEMO also have English and Chinese support.
How to Apply
1. Choose a provider from the comparison table below. 2. Prepare your Residence Card and payment method. 3. Apply online or visit a store. 4. Receive your SIM (1-3 days for delivery). 5. Insert and activate.
