Japan AI Regulatory Hub
Verification required. Claims on this page about Japanese law were compiled on 7 October 2026 from secondary web sources and from memory of the law. No primary legal text was read, and each claim is tagged [Reported], [Recalled], [Conflict] or [Unverified] as explained on the section home page. Check the primary text before relying on any of them. This is not legal advice.
This page maps Japanese laws, guidance and standards that bear on AI to the wiki's controls.
1. Regional model
Japan puts soft law first. Obligations on private firms come mainly from existing laws (privacy, copyright, consumer and sector rules). The AI Promotion Act sets principles and national coordination. The guidelines are voluntary, and they are the reference that buyers use [Reported].
