Japan did formally ask OpenAI to avoid conduct that could infringe Japanese intellectual property after Sora 2 launched and videos resembling recognizable anime, manga and game franchises circulated online. That was a policy warning and request—not a lawsuit, fine or court ruling that OpenAI had committed copyright infringement.
What Japan asked OpenAI to do
In October 2025, Japan’s government, through its intellectual-property policy apparatus, urged OpenAI to refrain from acts that would constitute infringement of Japanese intellectual property. Officials described anime and manga as irreplaceable cultural assets and warned that continued non-compliance could bring legal and political consequences. Reports disagree about the individual official who made the statement, so the safest description is the minister responsible for intellectual-property and AI strategy.
The request followed the online spread of Sora 2 clips that appeared to imitate recognizable Japanese characters, settings and visual identities. It was not an adjudicated finding. The available record does not show that Japan sued or fined OpenAI, obtained an injunction, or secured a court judgment holding the company liable.
Contemporary coverage cited clips resembling franchises such as Dragon Ball, Bleach and Spirited Away, while other reports mentioned Nintendo- and Pokémon-associated characters. Those examples came from social-media circulation and reporting; they were not authenticated by the Japanese government as particular acts of infringement or established as outputs from a confirmed training source.

Why Sora 2 became a flashpoint
OpenAI launched Sora 2 on September 30, 2025. Its launch materials described a video-and-audio model capable of realistic scenes, synchronized dialogue and sound effects, and anime-style generation. (OpenAI’s launch announcement) The combination of recognizable fictional characters and a rapidly shareable video format made disputed clips visible almost immediately.
A video that “looks like” a famous franchise can raise legitimate rights concerns, but appearance alone does not answer the legal question. The relevant facts include what the user asked for, what the output actually reproduces, which work or character is involved, where the conduct occurred and what evidence exists about copying.

Copyright questions that remain separate
Training or refinement data
One question is whether copyrighted Japanese works were included in data used to train or refine Sora 2. Evidence that a model may have learned from protected material is not the same as proof that a particular generated video infringes, and a disputed output does not by itself prove that its exact source work appeared in training data.
The generated output
Another question is whether a video reproduces protected expression. A broad “anime” aesthetic, color palette or storytelling convention is not automatically protected as a single copyright. A video that reproduces a recognizable character, costume, logo, setting, scene or storyline may present a stronger claim, depending on the work and jurisdiction.

Other rights
Copyright is only one possible theory. A clip can create trademark, passing-off, unfair-competition, likeness or publicity-rights, moral-rights, attribution or contractual licensing issues even when copyright infringement is uncertain. Platform terms and moderation rules do not determine whether an output is lawful.
Who could be responsible
Potential responsibility could involve the prompting user, OpenAI, a rights holder’s licensing arrangements or more than one party. The answer depends on jurisdiction, authorization, the output, the prompt, notice and control, and evidence of copying. Definitive conclusions require legal review of the specific work and facts.

Government warning and rights-holder action were different events
Japan’s government request should not be merged with later activity by the Content Overseas Distribution Association (CODA), which represents Japanese content interests in overseas distribution and anti-piracy work. A Cabinet Office working-group document records the following sequence:
| Date | Event | What it establishes |
|---|---|---|
| September 30, 2025 | Sora 2 launched | OpenAI introduced the video-and-audio model. |
| October 2025 | Japanese government warning | OpenAI was urged to avoid potentially infringing conduct; this was not a court decision. |
| October 27, 2025 | CODA request to OpenAI | CODA sought assurances that member content would not be used for unauthorized model training and asked for serious handling of complaints and consultations. |
| December 1, 2025 | Discussions with OpenAI | The issue continued through information-sharing and consultations. |
| April 1, 2026 | Planned CODA investigation and information gathering | Continuing scrutiny and fact-finding, not proof that every disputed output was unlawful. |

OpenAI’s responsible-launch materials described visible and invisible provenance measures, including C2PA metadata, watermarking, automated detection and reporting systems, moderation and controls intended to address likeness risks. (Launching Sora responsibly; Sora 2 System Card) These measures can help identify or restrict content, but they are not copyright licenses and do not make an otherwise infringing video lawful.
Best Value
OpenAI’s initial Sora 2 materials did not establish that all Japanese anime, manga or game characters were licensed. Secondary reporting described a rights-holder opt-out approach rather than universal prior permission. That description should be treated as reporting, not as proof that Japan enacted a blanket opt-in rule for Sora.
OpenAI announced a separate Disney agreement on December 11, 2025, covering more than 200 Disney, Marvel, Pixar and Star Wars characters. The deal did not resolve disputes involving unrelated Japanese properties and did not retroactively authorize them. (OpenAI’s Disney announcement)
What happened to Sora afterward
The dispute is now historical in product terms. OpenAI says the Sora web and app experiences were discontinued on April 26, 2026, and that the Sora API is scheduled to be discontinued on September 24, 2026. (OpenAI Help Center) The record does not establish that Japan’s warning caused the shutdown, nor does discontinuation resolve whether any earlier output infringed.
What is still unresolved
- Whether particular Sora clips reproduced protectable expression rather than general ideas or style.
- Whether specific Japanese works appeared in Sora’s training or refinement data.
- How liability would be allocated among users, OpenAI and other parties under Japanese, United States or other law.
- Whether future OpenAI systems will use broader licensing, stronger exclusion controls or different complaint procedures.
Japan’s warning therefore matters as a policy intervention and as evidence of sustained rights-holder concern. It should not be rewritten as proof that OpenAI “stole anime,” that every anime-style generation was illegal, or that a court had already decided the case.
The Bottom Line
Japan urged OpenAI to prevent potentially infringing use of Sora 2 after franchise-like videos went viral. The government request, CODA’s later fact-finding and OpenAI’s safeguards show an unresolved licensing and liability dispute—not a final copyright judgment—and Sora’s web and app products have since ended.
