AI regulation in Japan (2026)

The Cabinet adopted the Basic Plan for Artificial Intelligence ('Revitalizing Japan through Trustworthy AI'), the strategic blueprint mandated by the AI Promotion Act that sets four policy directions: accelerating AI use, strengthening development capacity, improving trustworthiness, and transforming society. It operationalizes the new statutory framework.

The provisions establishing the AI Strategy Headquarters—chaired by the Prime Minister with all Cabinet ministers as members—came fully into force, giving Japan a whole-of-government coordinating body for AI policy.

Japan's Parliament enacted the Act on Promotion of Research and Development and Utilization of AI-Related Technologies, an 'innovation-first' fundamental law setting national principles and policy direction without imposing direct penalties on private actors.

Japan's ministries consolidated prior guidance into unified non-binding guidelines defining roles for AI Developers, Providers, and Business Users, setting ten cross-sector principles and practical checklists—forming the core of Japan's soft-law regime ahead of legislation.

Following ~25,000 public comments, the Cultural Council's Legal Subcommittee clarified how the Article 30-4 training exception applies to generative AI, noting it does not cover uses that unreasonably prejudice rightsholders (e.g., style-imitating fine-tuning).

Under Japan's G7 presidency, leaders agreed the world's first international framework for advanced AI, including guiding principles and a voluntary code of conduct for organizations developing the most advanced foundation models and generative AI.

At the G7 Hiroshima Summit, Japan initiated a coordinated international process on generative AI governance, cementing its strategy of shaping global norms while pursuing light-touch domestic rules.

Building on its R&D principles, Japan published non-binding guidelines for AI users that helped implement the OECD AI Principles and extended the country's multi-stakeholder soft-law model from developers to deployers.

Japan's Cabinet-level council issued seven foundational principles (human-centric, education, privacy, security, fair competition, fairness/accountability/transparency, innovation), establishing the soft-law value framework that underpins all later AI policy.

Through the Conference toward AI Network Society, Japan published nine non-binding R&D principles intended to feed G7/OECD debates—an early foundational document that seeded both Japan's domestic governance and the 2019 OECD AI Principles.
