AI governance in Japan.

Japan passed its first AI law in May 2025 — deliberately innovation-first with no penalties and no prohibitions. But METI guidelines define the commercial standard of care, and the AI Strategic Headquarters chaired by the Prime Minister signals national seriousness.

METI/MIC AI Guidelines: 10 principles

The operative compliance benchmark — treated as standard of care by courts, regulators, and enterprise buyers.

Human-centred— AI must respect fundamental human rights and dignity

Safety and security— AI systems must be safe and secure throughout lifecycle

Fairness— AI must treat people fairly and avoid unjust discrimination

Privacy protection— Personal information in AI must be handled lawfully (APPI)

Transparency— AI decision processes should be explainable to stakeholders

User control— People should maintain meaningful control over AI affecting them

Accountability— Organisations must be accountable for their AI systems

Innovation— Governance should enable, not restrict, beneficial AI innovation

International cooperation— Japan actively shapes global AI governance norms (Hiroshima Process)

Social benefit— AI should contribute to solving societal challenges

What makes Japan different from every other major AI jurisdiction

Japan is the only major economy to have passed dedicated national AI legislation with no mandatory compliance obligations whatsoever. No prohibited AI uses, no conformity assessments, no pre-deployment registration, no financial penalties.

Enforcement is entirely reputational: Article 25(2) of the AI Promotion Act authorises public naming of non-cooperating operators. In January 2026, the Prime Minister's Chief Cabinet Secretary used this power for the first time — reviewing AI-generated deepfake content.

But non-compliance has real commercial consequences. Enterprise buyers, government procurement, and export partners all treat the METI guidelines as the compliance standard. Being named as non-cooperative creates reputational and commercial damage that in practice functions as a significant incentive to comply.
