CODA said many outputs closely resembled Japanese works, but that was an allegation—not a court finding or public audit of Sora’s training data. The request was not a lawsuit. OpenAI later discontinued Sora’s web and app experiences, but the shutdown did not settle the underlying copyright questions.
What happened between CODA and OpenAI?
OpenAI announced Sora 2 on September 30, 2025, as a video-and-audio generation model. On October 27, Japan’s Content Overseas Distribution Association (CODA) submitted a written request to OpenAI; CODA published its account the following day. The request concerned both the material used to develop Sora 2 and videos the system generated. OpenAI’s Sora 2 announcement; CODA’s statement on its request.
CODA said it had seen many Sora 2 outputs that closely resembled Japanese content or images. It argued that this pointed to Japanese content being used as machine-learning data without permission, and said copying specific works in the machine-learning process could infringe copyright. Those are CODA’s claims and legal assessment. The public statement does not provide OpenAI’s training records, a technical audit, or a court’s determination that particular Ghibli or Bandai Namco works were used.
CODA’s two central requests were that OpenAI not use member companies’ content to train Sora 2 without authorization, and that it respond seriously to member companies’ claims and inquiries about copyright infringement in Sora outputs. The cited statement does not announce a damages demand, court filing, injunction request, or licensing settlement.

Who was represented—and what did Ghibli and Bandai Namco do?
The challenge was made by CODA, not presented in the primary statement as separate legal action personally filed by Studio Ghibli or Bandai Namco. CODA is a Japanese organization involved in overseas distribution and anti-piracy work. Its request was made at the request of member companies and addressed a broader group of rights holders and media interests than the two names in many headlines.
Studio Ghibli and Bandai Namco are prominent examples of the Japanese entertainment businesses whose catalogs made the dispute especially visible. Other represented interests included game, film, music, and publishing companies and organizations. The CODA statement does not establish that Ghibli or Bandai Namco individually authored or signed the request. “Bandai Namco” is the more accurate shorthand than “Bandai” for the company commonly identified in coverage of the challenge. CODA’s statement.
Why training data and generated videos are separate questions
What may happen during training
A training-data dispute asks whether copyrighted material was copied, processed, or otherwise used in making or training a model, and whether that use was lawful under the relevant jurisdiction’s rules. CODA’s concern was that Japanese works had been incorporated into Sora’s machine-learning data without permission. The public evidence cited here does not identify particular files in Sora 2’s training set, so it cannot establish that a named Ghibli film or Bandai Namco game was included.
What happens when someone generates a video
An output dispute concerns a particular video: what the user asked for, what the model produced, and whether the result reproduces protected expression such as an identifiable character, scene, image, or logo. CODA said many outputs closely resembled Japanese content, but its public statement does not supply a catalog of examples or forensic comparisons.

A resemblance alone does not reveal how it arose. Possible explanations can include training exposure, references supplied by a user, prompt wording, widely circulated descriptions, genre conventions, memorization, or coincidence. Distinguishing among them requires evidence about the specific prompt, output, source work, and model—not a conclusion drawn from a broad visual similarity.
Why “style” is not the same as copying a work
A broad aesthetic resemblance is a different factual question from reproducing a specific character, composition, frame, or logo. Copyright, trademark, publicity, and other rights may raise distinct issues, and the analysis can depend on what was generated and where it was used. The earlier public debate about prompting image models for a general “Ghibli-style” look should not be treated as proof that Sora 2 used Ghibli works as training data, or as interchangeable with CODA’s video-focused allegations.
Why CODA objected to an opt-out approach
The dispute also concerned who must act before content is used. In an opt-out model, a rights holder objects or requests exclusion after a company has adopted a system for gathering or using material. In a permission-first model, the company obtains authorization before using the material. CODA argued that an opt-out mechanism did not, by itself, resolve possible liability under its interpretation of Japanese copyright law.
That position should be attributed to CODA, not treated as a definitive statement of Japanese law. The legal outcome can depend on the acts involved, the rights asserted, where copying or processing occurred, and the jurisdiction whose law applies. A Japanese association’s view does not automatically determine liability in every country.
Was there a lawsuit, and what did OpenAI say?
The CODA and OpenAI primary sources cited here establish a written request and later discussions, not a court lawsuit or judgment. CODA later said it continued sharing information and discussing rights protection with OpenAI. That is materially different from Ghibli or Bandai Namco suing OpenAI, a court ruling that OpenAI infringed copyright, or CODA winning a case. CODA’s later update.
OpenAI’s launch and safety pages describe Sora’s product, safeguards, and content controls, including measures related to provenance and likeness. They are not a point-by-point public legal rebuttal to CODA’s October request. CODA’s account says discussions continued, but does not disclose their full substance.

OpenAI told CODA on March 27, 2026, that Sora 2, including its app and API, would be discontinued. OpenAI’s Help Center says the Sora web and app experiences ended on April 26, 2026, and lists September 24, 2026, as the scheduled API discontinuation date. Because that API date has passed, the cited page establishes the schedule but does not, by itself, confirm whether the API actually ceased operation as planned. CODA’s update; OpenAI’s Sora discontinuation information.
OpenAI directed users to export Sora content through sora.chatgpt.com/sunset and described the applicable export period and eventual deletion of Sora-related data. A product shutdown is not proof that CODA’s legal position prevailed, nor does it settle questions about past training, earlier outputs, exported videos, or other video-generation services. CODA described the discontinuation as a milestone in its efforts while warning that broader generative-AI risks remained.

What the dispute leaves unresolved
The case illustrates why copyright debates about generative AI need more than a claim that a result “looks like” a familiar property. Rights holders and AI companies may disagree about whether and how material entered training, what permission or exceptions apply, what an output reproduces, and what controls should be available. Resolving those questions can require clear records of source material, the steps used to process it, the relevant user prompts and outputs, and the applicable laws.
CODA’s challenge also put a governance choice into focus: should rights holders have to discover uses and opt out, or should companies obtain permission before using entertainment catalogs? The October 2025 request raised that question, but the public record cited here does not establish a judicial answer. Sora’s discontinuation changes the product’s status; it does not resolve the wider dispute over how AI systems should handle copyrighted works and outputs that resemble recognizable properties.
