On June 4, 2025, Japan promulgated its first comprehensive AI-related legislation, the Act on Promotion of Research and Development and Utilization of Artificial Intelligence-Related Technologies (the “AI Promotion Act” or “Act”). The new law outlines the principles of AI development and use, while ensuring its safety. The AI Promotion Act also establishes the government’s role in guiding AI research, development and application through future policy measures and oversight mechanisms.
The framework sets the stage for future measures, which are expected to proceed at a rapid pace. Notably, the government plans to establish an “AI Strategy Headquarters” within the Prime Minister’s Cabinet by autumn 2025, which will serve as a central body for launching concrete policies in Japan. The Prime Minister has also instructed the government to formulate a “Basic AI Plan” to promote the development and utilization of AI by winter 2025, based on the AI Promotion Act.
