My Number Card for Foreigners in Japan: A Quick Start Guide

Is there a My Number Card for foreigners in Japan? What are MyNa Points (shopping points)? How do I apply for a plastic My Number Card in English? And many more of your frequently asked questions. 

If you've newly arrived in Japan or plan to move to Japan soon, this quick start guide on Japan's My Number System is for you. 

What is My Number and the My Number System? 

Launched in 2015, the My Number System (マイナンバー制度 = mai namba seido) aims to streamline and digitize administrative procedures for residents by reducing paperwork and linking information among agencies. 

Also referred to as kojin bango = 個人番号  (Individual Number), the My Number System assigns a unique 12 digits to all residents in Japan who have a resident record (住民票 = jyuminhyo)

Residents and local and central governments use the 12-digit number and accompanying plastic ID card (with IC chip) for various social security and tax procedures.

What's the difference between My Number, My Number Card, My Number notification card, and Individual Number Notice? 

My Number refers to the unique 12-digits assigned to each resident of Japan. My Number Card refers to the plastic ID card that contains the individual's photo, name, address, birth date, and place of residence. My Number notification card is the format in which residents (before May 25, 2020) received notice of their assigned individual number (replaced by the Individual Number Notice post-May 25, 2020).

Theoretically, all residents have been issued a My Number notification card (マイナンバー通知カード = mai namba tsuuchi caado) or an Individual Number Notice informing them of their assigned 12-digit My Number. However, less than half of Japan's residents have applied for the plastic My Number Card

Is there a My Number Card for foreigners in Japan? 

All foreigners in Japan who plan to stay longer than 3 months can obtain a My Number Card. (Note: Temporary visitors, diplomats, and officials are not assigned a 12-digit number during their stay.) 

When foreigners register for the first time at their local ward office, they are issued an individual 12-digit sequence (My Number) that will remain the same their entire life. 

This 12-digit number (Individual Number Notice) will be sent via registered mail to their domicile a few weeks after applying for a residence certificate. 

If the individual is not at home when the registered mail arrives, there will be a notice in the mailbox regarding the undelivered mail. Follow the instructions on the notice and have the mail redelivered. Or pick up the mail at the post office. 

Having a 12-digit number assigned to you does not yet mean you are a My Number Card holder. You must apply for the plastic My Number Card using the digits assigned to you through your Individual Number Notice.  

How do I benefit from a plastic My Number Card? 

The plastic My Number Card streamlines various paperwork processes for residents of Japan. My Number Card holders can use the card to perform the following activities:

  9. Use in conjunction with the government's COVID-19 vaccination app to show vaccination status.

  10. Get MyNa (short for "My Number") points when fulfilling campaign conditions.

What are MyNa points (My Number points)? How do I get them? 

MyNa points (My Number points) refer to the government's incentive campaign in 2020 to speed up the adoption and penetration rate of plastic My Number Cards.
