You can now use your My Number Card for convenient online filing of Japanese income tax returns (e-Tax) and municipal/prefectural tax returns (eL-Tax) via smartphone or computer, starting with 2026 filings for 2025 income. My Number Card enables secure identity verification using IC chip scanning, requiring a 4-digit PIN for authentication and a 6-16 digit signature password.
This also eliminates the need to submit paper documents for many procedures.
Ensure your card is valid and you know your passwords before beginning the online filing process.

On January 31, 2025, the City began operating a “No-Writing Counter Service” using the government-promoted system.
The "No-Writing Counter Service" is a system that allows city hall visitors to complete various forms without writing them by hand at the counter by reading their My Number Cards.
The service reduces the time spent at the counter and waiting time by eliminating the need to fill out application forms. At the beginning, the service will be provided sequentially starting with the procedures that are available depending on the situations at each counter.

With the integration of the My Number card and the National Health Insurance Card card, the National Health Insurance Card has been discontinued after December 2, 2024.
To avoid the hassle of managing paper certificates, it is recommended that you transition to the My Number Card for health insurance. However, a "Certificate of Eligibility" is issued as a substitute for the traditional insurance card that can be used at medical institutions to ensure that you can still receive care.
