Studio Ghibli Demands OpenAI Stop Using Content for Sora 2 AI Training (2026)

Studio Ghibli and Other Japanese Content Producers Urge OpenAI to Cease Training Sora 2 with Their Intellectual Property

The Content Overseas Distribution Association (CODA), a Japanese trade group representing prominent animation studios and content creators, has issued a formal letter to OpenAI, demanding an immediate halt to the use of their copyrighted material in the training of the Sora 2 AI video generation platform. This move comes as a response to the growing concerns over AI-generated content and its potential to infringe upon the rights of original creators.

CODA's letter highlights a critical issue: the similarity between the content produced by Sora 2 and the works of Japanese content creators, including Studio Ghibli. The group asserts that this similarity is a direct result of using Japanese content as machine learning data, which raises serious copyright infringement concerns.

The association's mission is to protect and promote Japanese content overseas while combating piracy. In their letter, CODA emphasizes that under Japan's copyright laws, prior permission is essential for using copyrighted works, and subsequent objections are not sufficient to avoid liability for infringement. They argue that OpenAI's opt-out system for copyright holders does not align with Japanese legal standards.

CODA's concerns extend beyond the use of their content. They demand that OpenAI stop utilizing member content for machine learning without explicit permission and respond to inquiries regarding copyright infringement related to Sora 2's outputs. This request is particularly significant given the potential for AI-generated content to mimic the unique style and aesthetics of renowned studios like Studio Ghibli.

The controversy surrounding AI-generated art and its impact on intellectual property rights is not new. Hayao Miyazaki, the co-founder of Studio Ghibli, has previously expressed strong disapproval of AI-generated animation, calling it an insult to life itself. This sentiment resonates with CODA's stance, as they strive to protect the creative works of their members.

The letter was first reported by Automaton, a gaming news site, and it underscores the growing tension between AI developers and content creators. As AI technology advances, the need for clear guidelines and ethical practices in content generation becomes increasingly vital to ensure the protection of intellectual property rights.
