Japan Introduces Disclosure Requirements for Generative AI Companies

Japan has implemented new legislation establishing disclosure requirements for companies developing generative Artificial Intelligence. The statute, highlighted in Jenner & Block LLP´s April 2025 Japan Newsletter, aims to ensure greater transparency about how generative Artificial Intelligence platforms operate and manage data.

The new rules are designed to address growing regulatory and ethical considerations associated with generative Artificial Intelligence technologies. Companies subject to the law must provide clear information on their models, sources of training data, and potential risks, a move viewed as a significant step toward accountability and user protection in emerging digital markets.

This development aligns Japan with other jurisdictions imposing oversight on Artificial Intelligence systems, reflecting international momentum toward trustworthy and responsible technology deployment. Legal and technology professionals are closely monitoring these changes, recognizing their implications for compliance, innovation, and cross-border business activity in the broader Artificial Intelligence ecosystem.
