Government document outlines disclosure demand

The Cabinet Office material, dated October 22 and posted on its official site (cao.go.jp), carries the message that Japan is asking generative AI providers to open up information on how their models are trained, including the data used.

The document, signed by Minister Furukawa, forms part of the Japanese government's policy communications on generative AI. The exact scope of the disclosure being requested — and whether it is binding on companies — is not specified in the available material.

The demand comes amid growing international scrutiny of how large language models are built, with governments weighing transparency requirements against the protection of proprietary training data.

The position stated by Japan's Cabinet Office on disclosure of generative AI training methods and data is True.
