In Japan, the My Number system has become an essential part of daily life, and the My Number Picture represents a significant evolution in how citizens interact with government services. This unique identification photograph, linked to the 12-digit Individual Number (My Number) assigned to every resident, serves as a crucial component of Japan's digital transformation efforts. Understanding what it is, how it works, and why it matters can help both residents and businesses navigate the increasingly digital landscape of Japanese administration.
What is a My Number Picture?
A My Number Picture is an official photograph associated with Japan's Individual Number system, introduced in 2016 as part of the country's Social Security and Tax Number System. Unlike traditional ID photos, this image is digitally stored and linked to your unique 12-digit My Number, which appears on the My Number Card (Individual Number Card). The photo must meet specific requirements set by the Japanese government, including recentness, clarity, and standardized dimensions.
The My Number Picture serves multiple purposes beyond simple identification. It enables secure authentication for various government services, tax filings, and social security procedures. When you apply for a My Number Card, you must submit a photo that meets strict specifications: taken within the last six months, showing your full face without hats or sunglasses, with a plain background, and in a specific size format.

Technical Requirements for My Number Pictures
The Japanese government has established precise technical standards for My Number Pictures to ensure consistency and security across all applications. These requirements are designed to facilitate accurate facial recognition and prevent fraud.
| Requirement | Specification |
|---|---|
| Photo Age | Taken within the last 6 months |
| Dimensions | 4cm × 3cm (width × height) |
| File Format | JPEG |
| File Size | Between 20KB and 7MB |
| Background | Plain, light-colored background |
| Face Visibility | Full face visible, no hats or sunglasses |
How to Take a Compliant My Number Picture
Taking a proper My Number Picture requires attention to detail. The photo must clearly show your facial features for identification purposes. Here are the key steps to ensure your photo meets government standards:
- Choose a well-lit environment with even lighting to avoid shadows on your face
- Position yourself against a plain, light-colored background
- Look directly at the camera with a neutral expression
- Remove hats, sunglasses, and any accessories that obscure your face
- Ensure your hair doesn't cover your eyes or significant portions of your face
- Maintain a natural posture without tilting your head
Many photo studios across Japan now offer specialized My Number Picture services, ensuring compliance with all government requirements. These studios use calibrated equipment and trained staff who understand the specific standards. Alternatively, you can take the photo yourself using a digital camera or smartphone, provided you follow all the technical specifications.

Digital Submission and Storage
The digital nature of the My Number Picture represents a shift from traditional paper-based identification systems. Once taken, the photo can be submitted electronically when applying for a My Number Card or updating personal information. The image is stored in a secure government database and linked to your Individual Number.
This digital approach offers several advantages. It reduces the need for physical document carrying, enables faster processing of applications, and allows for remote verification of identity. The system also supports various online services, from tax filing to accessing government benefits, all through secure digital channels.
Privacy and Security Considerations
Given the sensitive nature of the My Number Picture and the associated Individual Number, privacy and security are paramount concerns. The Japanese government has implemented strict data protection measures to safeguard personal information. The My Number system operates under the Act on the Use of Numbers to Identify a Specific Individual in Administrative Procedures.
Access to My Number Pictures is limited to authorized government agencies and specific private entities that have obtained proper consent. Unauthorized use or disclosure of My Number information can result in significant penalties. Citizens have the right to request information about how their data is being used and can file complaints if they believe their privacy has been violated.
Benefits of Having a My Number Card with Picture
The My Number Card with your official picture has become increasingly valuable in daily life. Beyond its primary identification function, it serves as a multi-purpose credential that streamlines various administrative processes.
- Convenience: Acts as official identification for various services without needing separate documents
- Digital Services: Enables access to e-government services and online applications
- Banking: Can be used as identification for opening bank accounts and financial transactions
- Healthcare: Facilitates medical record sharing between healthcare providers
- Disaster Response: Helps verify identity during emergencies and disaster situations
Future Developments
Japan continues to expand the functionality of the My Number system and its associated picture. Recent initiatives include integration with smartphone applications, allowing the My Number Card to function as a digital ID on mobile devices. The government is also exploring ways to use the My Number Picture for more seamless authentication across different services.
As digital transformation accelerates, the My Number Picture will likely play an even more central role in how Japanese citizens interact with both government and private sector services. The system represents a model for other nations considering similar digital identity initiatives, balancing convenience with robust privacy protections.
For residents and foreign nationals living in Japan, understanding and properly maintaining your My Number Picture is becoming increasingly important. Whether applying for the first time or updating existing records, following the specified requirements ensures smooth access to the growing range of services that rely on this digital identification system.
