Japan AI Promotion Act

Act on Promotion of Research, Development and Utilisation of AI-Related Technologies (officially abbreviated “AI Act”)

National Diet of Japan; Cabinet (AI Strategy Headquarters) · Act No. 53 of 2025 (令和七年法律第五十三号)

This is a principles-and-promotion statute, not a regulatory one. It has four chapters and 28 articles plus supplementary provisions: Chapter 1 general provisions (purpose, definitions, basic principles, responsibilities of the State, local governments, research institutions, utilisation businesses and the public, strengthened coordination, legislative measures); Chapter 2 basic measures (promotion of R&D, shared facilities, ensuring appropriateness, workforce, education, research, international cooperation); Chapter 3 the AI Basic Plan; Chapter 4 the AI Strategy Headquarters. A full-text search for “penal provisions” returns zero hits — the Act imposes no penalties and no licensing, filing, assessment or labelling duty on companies. Article 7, addressed to “utilisation businesses”, is a responsibility clause: they should actively use AI in line with the basic principles to make their operations more efficient and create new industries, and must cooperate with measures implemented by the State and local governments. Article 13 provides that the State shall develop guidelines consistent with international norms and take other necessary measures to ensure appropriate R&D and use — so the concrete conduct rules sit in those guidelines and in existing law (the APPI, copyright, product liability, sectoral regulation), not in this Act.

Does this apply to me?

The Act imposes no directly enforceable administrative duty on Chinese AI companies. Its practical significance is threefold: (1) the Art. 2 statutory definition of “AI-related technologies” — technologies needed to realise, by artificial means, functions substituting for human cognitive, reasoning and judgement capabilities, and technologies relating to information-processing systems that process input using them and output results — becomes the shared terminology for Japanese policy and contract drafting; (2) the Art. 7 responsibility of utilisation businesses means companies operating in Japan are expected to cooperate with government measures, in practice by responding to surveys, participating in guideline development and supplying information; and (3) the Art. 13 guidelines and the Art. 18 Basic Plan set out Japan’s stated expectations for AI governance, which public procurement and large-enterprise due diligence will probe. Any claim that Japan already has “AI Act penalties” or “high-risk AI obligations” is factually wrong.

Application timeline

  1. 2025-06-04

    Act promulgated and, on the same day, in force (Act No. 53 of 2025)

    Article 1 of the supplementary provisions: the Act commences on the day of promulgation, except Chapter 3 (AI Basic Plan), Chapter 4 (AI Strategy Headquarters) and supplementary Articles 3 and 4. What applies from this date is Chapter 1 (purpose, definitions, basic principles and the responsibilities of the State, local governments, research institutions, utilisation businesses and the public) and Chapter 2 basic measures, including the Art. 13 duty on the State to ensure appropriateness.

  2. 2025-09-01

    Chapter 3 (AI Basic Plan) and Chapter 4 (AI Strategy Headquarters) commence

    The proviso to Article 1 of the supplementary provisions left the commencement of these two chapters to Cabinet Order, within three months of promulgation. The supplementary provision of the Cabinet Order on the AI Strategy Headquarters (Cabinet Order No. 281 of 2025) fixes that day as 1 September 2025, from which the AI Strategy Headquarters exists and the Art. 18 AI Basic Plan machinery operates.

  3. 2025-12-23

    Cabinet adopts the AI Basic Plan (“Japan’s revival through trustworthy AI”)

    The Basic Plan is the government-wide policy document required by Art. 18; it includes the measures leading to the APPI amendment enabling AI development characterised as statistics creation.

Obligations (3)

Each states its trigger, the evidence to retain and the clause it comes from

As a “utilisation business”, cooperate with State and local AI measures

Severity LowArt. 7

Article 7 defines a “utilisation business” as a person intending to develop or supply products or services using AI-related technologies, or otherwise to use such technologies in business activities. It requires them to endeavour, in line with the basic principles, to make their operations more efficient and advanced and to create new industries through active use of AI, and to cooperate with measures implemented by the State under Art. 4 and by local governments under Art. 5. This is a responsibility clause, not a sanctionable duty; in practice it means responding to government surveys, taking part in guideline and standards development, and answering requests for information.

Applies when
Businesses that develop, supply or use AI products and services in Japan, including Chinese AI companies with a Japanese presence.
Evidence to retain
  • · Correspondence records of cooperation with government surveys and information requests
  • · Records of participation in guideline or standards development
  • · Internal AI utilisation policy document

Estimated first-time effort: 1–3 person-days (estimate, not a commitment)

Align with the Art. 13 State guidelines and the Art. 18 AI Basic Plan

Severity LowArts. 13, 18

Article 13 requires the State to develop guidelines consistent with international norms, and take other necessary measures, to ensure the appropriate conduct of AI research, development and use; Article 18 requires the government to adopt an AI Basic Plan. Companies should treat both as the baseline governance expectation for the Japanese market, fold them into their internal AI governance, and answer against them in public procurement and large-customer due diligence. The AI Basic Plan was adopted by Cabinet decision on 23 December 2025.

Applies when
Chinese companies selling AI products to Japanese government bodies or large enterprise customers.
Evidence to retain
  • · Mapping table between internal AI governance policy and the State guidelines
  • · Tracking record of Basic Plan measures relevant to the business
  • · Working papers for due-diligence questionnaire responses

Estimated first-time effort: 2–6 person-days (estimate, not a commitment)

Do not treat the Promotion Act as a substitute for compliance under existing law

Severity MediumArts. 1, 3, 13

Because the Act creates no penalties, approvals or filings, AI compliance in Japan must be assessed under existing law: the APPI (including the 2026 amendment), the Copyright Act (training and outputs), the Unfair Competition Prevention Act, product liability law, and sectoral regulation in finance, healthcare, automotive and telecommunications. Internally, companies should maintain an explicit mapping recording that the Japanese AI Act creates no standalone duties while the relevant duties sit in other statutes, so that the Act is not mistaken for a compliance clearance.

Applies when
All Chinese companies doing AI business in Japan, especially teams making market decisions on the premise that Japan has no dedicated AI regulation.
Evidence to retain
  • · Mapping of Japanese AI-relevant legal duties to statutes and owning functions
  • · Compliance status assessment under each applicable statute
  • · Legal-change monitoring mechanism and review records

Estimated first-time effort: 3–8 person-days (estimate, not a commitment)

Penalties

None. A full-text search of the Act for penal provisions returns zero hits: it contains no criminal penalties, and no non-penal fines, surcharges or business-improvement orders. Article 13 leaves “ensuring appropriateness” to State-issued guidelines, which are themselves non-binding. Legal exposure for AI in Japan continues to arise under the APPI, the Copyright Act, the Unfair Competition Prevention Act, product liability law and sectoral regulation.

Known uncertainty

The “no penalties” conclusion rests on a zero-hit full-text search for penal provisions in the official e-Gov XML and on the absence of a penalties chapter in the Act’s structure. Article 2 of the supplementary provisions contains a review clause, so Japan may later legislate duties and sanctions separately. The government guidelines referred to in Art. 13 were not separately retrieved in this pass; they are non-binding but may be imported into contracts and procurement requirements. The title of the AI Basic Plan and its Cabinet decision date of 23 December 2025 are taken from the citation in the PPC outline; the Plan itself was not retrieved in this pass, so its contents were not checked section by section.
