Overview of Cyber Law in Japan

Japan’s cyber law regime comprises statutes addressing data protection, cybersecurity, computer crime, and platform regulation. The landscape has evolved in response to the EU’s GDPR, the Budapest Convention on Cybercrime, high-profile data breaches, and the government’s digital transformation agenda under the Digital Agency (established 2021). Japan’s approach combines legislation, government guidelines, and industry self-regulation.

Data Protection: The APPI

The Act on the Protection of Personal Information (Law No. 57 of 2003 — APPI) is Japan’s primary data protection law. Originally effective in 2005, it was reformed in 2015 and 2020.
