Japan
Summary
Law: The Act on the Protection of Personal Information (Act No. 57 of 2003 as amended in 2020) (APPI)
Regulator: The Personal Information Protection Commission (PPC)
Summary: On April 1, 2005, the APPI entered into effect and governs general data handling in Japan. The Act on the Use of Numbers to Identify a Specific Individual in the Administrative Procedure (the My Number Act), on the other hand, regulates the use of certain individual social security codes (known as 'My Numbers'). Private sector amendments to the APPI entered into effect on April 1, 2022, and introduced new obligations associated with data subject rights, breach notification, data transfers, and the processing of pseudonymized data, among other things. The PPC, as well as other ministries, have released several guidelines to set out and clarify data protection requirements under the APPI and My Number Act.
Furthermore, Japan is a participant of the Asia-Pacific Economic Cooperation Cross Border Privacy Rules System (APEC CBPR) and has been recognized by the European Commission as providing an adequate level of personal data protection.
