Studio Ghibli-Backed Group Demands OpenAI Stop Using Japanese Art in AI Training
A major Japanese trade organisation representing Studio Ghibli and other publishers has formally demanded that OpenAI cease using Japanese copyrighted content to train its Sora 2 AI video generator. The move follows viral AI-generated videos that closely mimicked Ghibli’s iconic art style, which co-founder Hayao Miyazaki has previously criticised as clashing with the studio’s artistic philosophy.
Key Takeaways
- Japanese trade group CODA demands OpenAI stop using copyrighted Japanese content for Sora 2 training
- Association represents Studio Ghibli and other major publishers
- CODA argues AI outputs resembling Japanese works indicate copyright infringement
- OpenAI’s opt-out system conflicts with Japan’s copyright framework requiring prior permission
Formal Complaint Filed Against Sora 2
The Content Overseas Distribution Association (CODA) sent a written request to Sam Altman’s OpenAI on October 27, specifically targeting the Sora 2 video generation platform launched on September 30. CODA stated it had confirmed that “a large portion of content produced by Sora 2 closely resembles Japanese content or images,” indicating the likely use of Japanese works as training material.
Potential Copyright Violation Under Japanese Law
In its formal letter, CODA argued that reproducing copyrighted works during AI training could constitute copyright infringement under Japanese law, particularly when generated outputs closely resemble existing creative material. The association specifically challenged OpenAI’s opt-out approach, which allows copyright holders to remove their works after the fact.
CODA emphasized that Japan’s copyright framework generally requires prior authorization for using protected works, making the opt-out system fundamentally incompatible with local laws.
CODA’s Key Demands to OpenAI
The trade organisation presented two clear demands:
- OpenAI must immediately stop using CODA members’ content for Sora 2 training without explicit permission
- The company must provide sincere responses to copyright infringement claims from member companies
CODA urged OpenAI to find a balance between technological innovation and creators’ rights to ensure “the healthy development of AI technology.”
Previous Sora Controversy Involving Historical Figures
This development follows recent controversy where OpenAI paused the generation of images depicting Martin Luther King Jr. after objections from the civil rights leader’s estate. In an October 17 statement, OpenAI confirmed it had worked with The Estate of Martin Luther King, Jr Inc to ensure respectful treatment of the late leader’s image.
“At King, Inc.’s request, OpenAI has paused generations depicting Dr King as it strengthens guardrails for historical figures,” the company stated, following reports of users creating “disrespectful depictions” using the platform.
Growing Global Debate on AI Training Ethics
The CODA letter adds to intensifying international scrutiny over how AI companies source and use creative content for training their models. Governments and rights organisations worldwide are increasingly demanding greater transparency and explicit consent from creators whose works form the foundation of these AI systems.
