A new TV commercial campaign has been launched in Japan to inform citizens about the expiration and renewal process for MyNumber cards and digital certificates. MyNumber cards have different validity periods based on the age at issuance: 10 years for adults (18 years and older) and 5 years for minors. For non-Japanese residents, the card’s expiration aligns with their visa expiration date. Digital certificates embedded in the cards expire after 5 years, regardless of age. Renewal notices are typically sent before expiration, with the exact timing varying by municipality. Renewal procedures can be completed at local municipal offices, with some offering online and mail options. The campaign aims to raise awareness about these processes and encourage timely renewals to ensure continued access to digital services and identification.
