The Japanese government issues a unique number to every resident of Japan (both foreign and domestic). This number, also referred to as the Social Benefits or Tax Number, is protected by the My Number Act (Japanese version).
The responsibility to protect personal information and “My Number” data lies with our customers when using Google Cloud Platform. Google Cloud Platform products are ISO 27001 and ISO 27018 certified. These are international certifications related to practices to protect information (such as personal information and “My Number” data) and include appropriate access control measures.
