Large anime, manga and video game companies in Japan have required OpenAI to stop using his works without authorization to train your artificial intelligence model Sora 2. The petition was formally presented by the Content Overseas Distribution Association (CODA)an organization that brings together publishers such as Aniplex, Bandai Namco, Studio Ghibli, Square Enix, Kadokawa and Shueisha.
CODA announced on October 28 that it sent a written request to OpenAI asking you to stop training Sora 2 with copyrighted material. According to the organization, many results generated by the AI “clearly resemble real Japanese works,” which would indicate that the system was trained with copyrighted content, including characters, visual styles and recognizable scenes.

Possible violation of Japanese laws
In its statement, CODA warned that simply copying works during the machine learning process “could constitute a copyright violation” under Japanese law. Although OpenAI offers an opt-out system for creators, CODA maintains that the country's law requires obtaining prior permission before using any copyrighted work. Furthermore, they emphasize that “there is no mechanism that eliminates liability for infringement following a subsequent objection.”
A call for transparency
CODA also asked OpenAI to respond directly to queries from affected companies and clarify whether their model data includes unlicensed Japanese material. For now, OpenAI has not issued an official comment on the claim, while the debate over the use of copyrighted content to train artificial intelligence continues to grow both in Japan and the rest of the world.
Will this be the start of a new legal battle between the anime industry and artificial intelligence companies?
