How to Get Your My Number Card in Tokyo

A Complete Guide for Foreign Residents and Newcomers

If you’re living in Tokyo, one of the most important pieces of identification you’ll need is the My Number Card (マイナンバーカード), also known as the Individual Number Card. This government-issued ID is vital for accessing a range of public services, filing taxes, signing up for health insurance, and even using cashless payment apps. While every resident of Japan—citizens and foreign nationals alike—is issued a My Number, obtaining the actual My Number Card is a separate and optional (but highly recommended) step.

This guide will walk you through the complete process of getting your My Number Card in Tokyo, including eligibility, step-by-step application instructions, required documents, timeframes, tips for English-speaking support, and answers to frequently asked questions.

1. What Is the My Number System?

The My Number system was introduced in 2015 to improve administrative efficiency, reduce fraud, and streamline social services in Japan. Each resident receives a 12-digit individual number tied to their personal records for:

• Taxation

• Social security (health and pension)

• Disaster response

• MyNaPoint (cashless incentive programs)

What Is the My Number Card?

The My Number Card is a plastic IC card that includes:

• Your name

• Address

• Date of birth

• Gender

• Photograph

• 12-digit My Number (on the back)

It also functions as:

• A valid form of photo ID

• A health insurance card (opt-in)

• An e-tax signature tool

• A login for Japan’s government e-services (MynaPortal)

2. Who Needs a My Number Card?

While having a My Number is automatic (sent via mail to every resident), the My Number Card must be applied for. As of 2025, the card is not mandatory, but strongly encouraged.

You should get one if:

• You plan to stay in Japan long-term

• You want to use e-Tax or e-government services

• You need a Japanese photo ID (other than your residence card)

• You want to use health insurance via card

• You plan to access MyNaPoint or digital payment incentives

Foreign residents with a Resident Record (住民票, jūminhyō) are fully eligible.

3. Step-by-Step: How to Get Your My Number Card in Tokyo

Step 1: Receive Your My Number Notification Letter

After registering your address in Tokyo (typically at your ward office), you’ll receive:

• My Number Notification Letter (通知カード or 通知書)

• Application form (usually included)

Timeline: Arrives 2–4 weeks after moving in or changing residence.

Step 2: Submit Your My Number Card Application

There are several methods to apply for the card. All are free.

Option A: Online Application (Recommended)

1. Scan the QR code from your notification letter.

2. Upload a passport-style photo (must meet strict requirements).

3. Confirm details (name, address, etc.).

4. Submit.

Processing time: About 3–5 weeks

✅ Advantages: Fastest processing, English instructions available online.

Option B: Mail-in Application

1. Fill out the paper application form.

2. Attach a passport-style photo.

3. Mail to the address written on the form (Japan Post is fine).

Processing time: 5–6 weeks

Step 3: Receive a Postcard from the Ward Office

Once your card is ready, your local ward office will send a postcard notification (“交付通知書” – kōfu tsūchi-sho). This postcard informs you:

• Your card is ready

• Which office to visit

• What documents to bring

• Available pickup times (may require reservation)

Do not lose this postcard. You must bring it to pick up your card.

Step 4: Visit the Ward Office to Collect Your Card

You’ll need to bring:

• The postcard notification

• Your residence card (在留カード)

• One other valid ID (passport, driver’s license, health card, etc.)

• Completed PIN/password setup form (if included)

At the ward office:

• You’ll set a PIN (for online government use)

• Your identity will be confirmed via photograph and ID

• You will not receive the card by mail

⏱️ Time needed: 15–30 minutes (appointment may speed up the process)
