At the request of member companies, the Japanese anti-piracy organization CODA (Content Overseas Distribution Association) submitted a request to OpenAI, 2025 regarding the operation of Sora 2 (sora.chatgpt.com), which the company launched on September 30, 2025.
CODA has observed that the majority of the content created by Sora 2 closely resembles Japanese content or images. CODA determined that this was the result of using Japanese content as machine learning data. As with Sora 2, CODA considers the act of reproduction during the machine learning process to be a potential copyright infringement when certain copyrighted works are produced as copies or similar outputs.
According to reports, Sora 2 will be implemented in an opt-out manner based on requests from copyright holders. However, under the Japanese copyright system, prior permission is required in principle for the use of copyrighted works, and there is no system in place to avoid liability for infringement by filing a subsequent objection.
The requests currently submitted by CODA are as follows.
- In operating Sora 2, CODA requires that member content not be used for machine learning without the member’s permission. and,
- OpenAI will respond in good faith to complaints and inquiries from CODA member companies regarding copyright infringement related to Sora 2 output.
CODA, in cooperation with member companies, demands that OpenAI respond honestly in order to achieve both the healthy development of AI technology and the protection of the rights of rights holders and creators.
