Overview
- Industry group CODA, which includes Studio Ghibli, Toei Animation, Square Enix, Toho and others, sent a public letter on October 27–28 demanding OpenAI immediately cease using members' works and issue a formal response.
- CODA says a large share of Sora 2 outputs “resemble substantially” original Japanese images, concluding the model was trained on protected content.
- The group argues OpenAI’s voluntary opt-out system forces rights holders to police inclusion and may run counter to Japan’s copyright framework.
- Japan’s intellectual property minister, Minoru Kiuchi, warned OpenAI to ensure its systems respect local law, calling manga and anime irreplaceable cultural assets.
- OpenAI had not publicly responded as of November 4, after Sora 2’s September launch intensified concern by generating high-fidelity, realistic video.
