Japan's AI legislation: Agile governance creating competitive advantages

As the EU's Artificial Intelligence Act establishes a comprehensive regulatory framework for its member states and China adopts notably restrictive rules toward social stability and state control, how is AI governance taking shape in Japan?

The short explanation for Japan's AI regulations can be expressed in two words: agile governance. But recent developments have transformed this landscape significantly, with Japan now leading globally in innovation-first AI legislation that creates competitive advantages for growth-stage businesses.

In April 2024, Japan's Ministry of Internal Affairs and Communications and Ministry of Economy, Trade and Industry launched AI Guidelines for Business Ver 1.0, aligned with international discussions and trends.

These guidelines have since been updated multiple times, with Version 1.1 published in March 2025, demonstrating Japan's commitment to maintaining current and practical guidance for AI developers, providers and users.

Most significantly, Japan's Parliament approved the AI Promotion Act on May 28, 2025, making Japan the second major economy in the Asia-Pacific region to enact AI legislation.

This approach balances societal and individual rights while fostering innovation and the adoption of AI technologies. As a result, companies have opportunities to gain competitive advantages through AI governance implementation.

Japan's landmark AI legislation: The AI Promotion Act

The AI Promotion Act, officially titled the "Act on the Promotion of Research and Development and the Utilization of AI-Related Technologies," took effect on June 4, 2025, representing a watershed moment in global AI governance.

Unlike restrictive regulatory approaches adopted elsewhere, Japan's legislation is characterized as "not prescriptive but promotional," focusing on fostering domestic AI ecosystem development through cooperative governance.

The Act establishes five fundamental principles that serve as the foundation for Japan's AI legislation:

1. Alignment with existing national frameworks — ensuring AI development conforms with Japan's broader technology and digital society goals
2. Promotion of AI as a foundational technology — positioning AI as essential for economic and social development while considering national security
3. Comprehensive advancement — supporting systematic AI promotion across all stages from research to practical application
4. Transparency in development and use — requiring transparency to prevent misuse and protect citizens' rights
5. International leadership — actively participating in international AI norm formulation and cooperation

The legislation creates an AI Strategy Headquarters within Japan's Cabinet, chaired by the Prime Minister and including all Cabinet ministers, ensuring a whole-of-government coordinated approach to AI policy implementation.

Japan's human-centered approach to AI regulation

In 2019, Japan's government published the Social Principles of Human-Centered AI. According to this document, Japan's goal is to realize the world's first "AI-ready society" through a set of principles:

• AI must not infringe upon fundamental human rights
• Basic education and literacy must be ensured
• Privacy must be protected, security ensured, and a fair, competitive environment guaranteed
• Fairness, accountability and transparency are necessary
• AI innovation will be promoted through the close collaboration and cooperation of domestic and international stakeholders

These principles play out across three core philosophies:

1. Respect for human dignity
2. A sustainable society
3. A society where diverse backgrounds support individual well-being

The Centre for Strategic and International Studies (CSIS) points out similarities between Japan's Social Principles and the AI Principles set by the Organization for Economic Cooperation and Development (OECD), which acknowledge AI's potential alongside its risks and recognize welfare and wellbeing, with frequently cited AI benefits such as innovation, productivity and economic growth.

Importantly, with the introduction of comprehensive AI legislation, Japan aims to achieve its social principles through the use of AI, not through restrictions on the ever-evolving technology.

Current Japanese AI regulations and governance framework

The AI Promotion Act represents an evolution from Japan's previous approach, where AI was regulated primarily through existing laws. While these foundational laws remain important, the new legislative framework provides a more structured approach to AI governance.

Current Japanese AI legislation encompasses both the new promotional framework and existing regulatory foundations:

New legislative framework:

• The AI Promotion Act (2025) establishes strategic leadership and cooperative governance
• Updated AI Guidelines for Business (through Version 1.1, March 2025)
• AI Strategy Headquarters provides coordinated policy implementation

Existing legal foundations:

• The Copyright Act
• The Personal Information Protection Law
• The Unfair Competition Prevention Act
• Antimonopoly law
• The Economic Security Promotion Act

Further, business actors, which include the AI Developer, AI Provider and AI Business User involved in advanced AI systems, are encouraged to adhere to the Hiroshima Process International Guiding Principles for All AI Actors, as well as the Hiroshima Process International Code of Conduct for Organizations Developing Advanced AI Systems.

The AI Promotion Act's enforcement mechanism is notably unique, containing no explicit financial penalties for non-compliance.

Instead, it relies on a cooperative and reputational model where businesses are expected to "endeavor to cooperate" with government measures, leveraging Japan's business culture where corporate reputation carries significant weight.

Adapting to evolving sector-specific AI regulations

Japan's sector-specific approach creates opportunities for businesses to demonstrate leadership in responsible AI adoption. In May 2024, the government's AI Strategy Council met to discuss regulating the development of generative AI, with ongoing consultations focusing on mitigating risks in medical equipment, self-driving vehicles, and preventing AI applications in weapons production, crime, terrorism and human rights violations.

Recent analysis from Nikkei Asia indicates these developments represent a shift from purely voluntary compliance: "Until now, Japan has let companies self-regulate based on government-issued artificial intelligence guidelines in order to bolster growth." However, this evolution maintains Japan's innovation-first philosophy while providing clearer governance structures.

The AI market in Japan is projected to reach USD 27.1 billion by 2032, indicating substantial growth potential that regulatory approaches must carefully consider. This market opportunity, combined with Japan's supportive regulatory environment, creates significant advantages for companies that establish governance leadership early.

What should organizations do as these developments unfold?

Strive to integrate Japan's human-centric philosophies into your AI activities, from developing, provisioning and using AI systems to creating business value. Companies should also:

• Implement comprehensive AI governance frameworks that exceed minimum requirements
• Leverage automated governance tools to demonstrate transparency and accountability
• Build flexible compliance systems that can adapt to evolving regulatory guidance
• Establish cooperative relationships with government agencies and industry groups
• Invest in AI governance technologies that provide competitive advantages while ensuring compliance

Connecting the dots: AI regulatory trends across Asia-Pacific and beyond

Similar to Japan, the APAC regulatory scene is evolving, with each jurisdiction introducing AI frameworks for ethical development and deployment.

China and Singapore lead with comprehensive measures, while Hong Kong focuses on data protection, and Vietnam, Indonesia, and the Philippines establish legal guidelines for emerging AI applications.

Japan's AI Promotion Act distinguishes the country by explicitly prioritizing innovation promotion over restrictive regulation.

Unlike China's emphasis on social stability and state control, Japan maintains its commitment to industry self-regulation and voluntary compliance, creating competitive advantages for companies within its framework.
