Japan targets OpenAI over unauthorized anime content

Japan’s concern grows

The Japanese government has formally requested that OpenAI stop using manga and anime artwork without explicit permission. Many AI-generated videos on OpenAI’s app Sora 2 feature well-known characters and iconic visual styles.

Japanese officials say these works risk infringing copyright and cultural heritage. The issue has triggered debates about how generative AI should treat creative works. Japan calls anime and manga “irreplaceable treasures” to the world.

What is Sora 2 app?

OpenAI announced Sora 2 on Sept. 30, 2025: a short-clip video and audio generation model that can produce high-definition videos with synchronized sound and user-selectable styles, including outputs that some users have driven toward styles that resemble anime and manga.

Users quickly posted Sora 2-generated clips depicting characters resembling Pikachu, Mario, and other well-known franchise figures, content created by app users rather than by rights-holders, which alarmed copyright owners and Japanese officials.

Government’s formal request

Minoru Kiuchi, Japan’s Minister of State for Intellectual Property and AI Strategy, issued a formal request to OpenAI to refrain from infringing on Japanese IP.

The request asks for OpenAI to stop generating content featuring copyrighted characters or distinctive art styles unless rights-holders opt in. Masaaki Taira, Digital Minister, also called for stronger voluntary compliance.

Lawmakers are urging OpenAI to let rights-owners delete or block content. The government emphasizes proactive measures rather than after-the-fact remediation.

Opt-in vs opt-out controversy

Originally, OpenAI’s policy for content depiction relied in part on an “opt-out” model, where creators would request not to have their works used. Japan wants this changed to an “opt-in” model, giving permission in advance rather than relying on rights-holders asking to be excluded.

Critics say opt-out is unfair because many creators may not even know to opt out or may miss the chance. An opt-in system shifts more responsibility onto the AI maker. OpenAI has committed to giving more control to rights-holders.

Popular anime infringement examples

Right after Sora 2’s release, many shared videos featuring characters and styles from popular franchises. Examples include One Piece, Demon Slayer, Mario, Pokémon, and others. The videos are so faithful in style that many found them indistinguishable from the original content.

These examples have become central to Japan’s case as evidence of style copying. The sheer volume of such content is what prompted the government’s request.

Ministry statements

Minoru Kiuchi described manga and anime as “irreplaceable treasures” and said Japan is proud to share them globally. Masaaki Taira urged OpenAI to take voluntary action and respect Japanese creative output.

Member of parliament Akihisa Shiozaki warned that continued AI-generated content of copyrighted styles could threaten Japan’s creative industries. Officials emphasized that Japan should take a leading role in setting rules for AI and copyright. Public and political pressure is mounting.

Legal framework

Japan’s Act on the Promotion of Research and Development and the Utilization of AI-Related Technologies was passed in May 2025 and promulgated soon after; implementation of certain administrative chapters is staggered into summer/fall 2025.

The law, together with existing copyright rules, gives the government authority to investigate AI misuse and to request remedial action. Japanese copyright law distinguishes between training data and public depiction of copyrighted characters.

Rights-holders argue that using likenesses or distinctive characters without permission violates established law. The law’s grey areas are now under intense scrutiny.

Rights-holder control sought

Japan wants tools that give studios and creators more control over how their characters are used in AI-generated content. The government has asked OpenAI to enable the deletion or takedown of infringing content.

Also, rights-holders should be able to specify whether their characters are included at all. Granular permissions are being requested so that usage can be limited or blocked by those who own the IP. This would allow more respectful and controlled AI output.

Cultural risk and heritage

Officials say anime and manga are not just commercial products but central to Japan’s cultural identity and global soft power. They are seen as “treasures” that define Japanese cultural export and artistic reputation.

Mass imitation or misuse in AI could dilute or misrepresent those styles. The risk is that distinct art forms lose value if generic or infringing AI content becomes widespread. Japan emphasizes preserving authenticity.

Creators’ backlash

Japanese creators, studios, and fans have expressed concern over AI models using their styles or characters without compensation or attribution. Some see it as theft of creative labor. Others worry about revenue loss or brand dilution.

The volume of fan content and AI mimics has escalated outrage. Creators are pushing for stronger legal protections and better industry norms. The public mood is strongly protective of artistic integrity.

OpenAI’s response

OpenAI has acknowledged that Japanese art is influential and deeply connected with user demand. The company says it’s developing more granular control for rights-holders, similar to opt-in models for likeness, to specify how their characters are used.

OpenAI has said it is working on more granular controls for rights-holders and has earlier offered opt-out tools. Japanese officials are pressing for an opt-in model and stronger pre-permission or design-stage collaboration, and talks are reported to be ongoing.

Potential legal consequences

If OpenAI doesn’t respond or comply, Japan’s government could pursue legal or regulatory action. Under its IP strategy and AI laws, the government has mechanisms to ask firms to modify their behavior.

There are also concerns that OpenAI might face lawsuits from copyright holders. The enforcement could include penalties or forced compliance. The situation is rapidly evolving with both political and legal dimensions.

Global implications

Japan’s stance could set a precedent for other countries grappling with AI, IP, and imitation of style. If rules emerge here, similar demands may follow in Europe, the U.S., or elsewhere.

Platforms providing generative content may need stronger opt-in/opt-out policies globally. The balance between creative freedom and IP protection is now under international scrutiny. Japan aims to lead the global conversation.

Challenges for enforcement

Policing AI’s output is difficult. AI models generate millions of novel images and videos. Identifying which content actually infringes vs which is transformative is complex. Rights holders may find it hard to monitor all infringements.

There are technical, resource, and legal challenges in defining “style” vs. “copy.” Enforcement mechanisms must be robust but also fair. The ongoing development of tools for rights-holder control will be critical.

Policy evolution and proposals

Japan may push for stronger laws or regulations to require AI firms to respect IP upfront. Proposals include mandatory opt-in systems, clearer takedown procedures, permissions, and compensation. The government may also update AI legislation to clarify what constitutes infringement.

There is talk of requiring AI platforms to work with IP owners at the design/training stage. These developments reflect growing awareness of AI’s legal implications.

Final thoughts

Japan has drawn a firm line: generative AI must respect anime and manga as cultural heritage. OpenAI is under pressure to adjust Sora 2’s policies on character usage and style mimicry. The coming weeks will show whether OpenAI aligns with requests or faces stricter regulation.

Artists and rights-holders are watching closely. The case highlights broader debates about how AI interacts with creative work worldwide.
