The Japanese government has officially asked OpenAI to avoid copyright infringement (reportedly) Information media). This was in response to Sora 2's ability to generate videos featuring the likenesses of copyrighted characters from anime and video games.
Sora 2, launched by OpenAI on October 1, is capable of generating 20-second long videos in 1080p resolution, with sound.

The request was reportedly made online by the Cabinet Office’s Intellectual Property Strategy Headquarters. Kiuchi went on to describe manga and anime as “irreplaceable treasures” that Japan boasts to the world.

Article 16 The Artificial Intelligence Promotion Act covers research and investigation and says the government can “analyze cases in which the rights or interests of citizens are infringed upon by researching, developing, or utilizing AI-related technologies for improper purposes or by improper methods, and consider countermeasures based on these analyses.” However, as noted, The future of privacy forumsThe bill does not specify penalties for misuse of artificial intelligence, but instead calls on business operators to Cooperation measures.

Reuters report On September 29, OpenAI contacted studios and agencies a week before Sora 2 was released, giving them the option to opt out. However, it was not specified which studios were contacted.

in his October 4th Blog Post On Sora 2 (before IGN reports), OpenAI CEO Sam Altman says changes will be coming to the fledgling video generation application in the near future. “First, we will give rights holders more granular control over character generation, similar to an opt-in similarity model, but with additional controls,” Altman confirmed, adding that OpenAI will give rights holders “the ability to specify how their characters are used (including not using them at all).”
He acknowledged that there may be “some edge cases” in the character descriptions, but that this will be addressed in time. Altman also singled out Japan, saying, “We are particularly grateful for Japan's outstanding creative output – the depth of the connection between users and Japanese content is astonishing to us!”
