Japan Asks OpenAI To Stop Sora 2 From Infringing on 'Irreplaceable Treasures' Anime and Manga

(Wednesday October 15, 2025 @05:22PM (msmash) from the irreplaceable-treasures dept.)


The Japanese government has made a formal request asking OpenAI to [1]refrain from copyright infringement . The request came after Sora 2 began generating videos featuring copyrighted characters from anime and video games. Minoru Kiuchi spoke at the Cabinet Office press conference on Friday and described manga and anime as "irreplaceable treasures" that Japan boasts to the world.

The request was made online by the Cabinet Office's Intellectual Property Strategy Headquarters. Sora 2, which launched recently, generates twenty-second videos at 1080p resolution. Social media is getting filled with videos showing characters from One Piece, Demon Slayer, Pokemon and Mario. Digital Minister Masaaki Taira expressed hopes that OpenAI would comply voluntarily. He indicated that measures under Japan's AI Promotion Act may be invoked if the issue remains unresolved.

Even so, infringement was supposed to be based on "substantial similarity", not "training". What they mean is to drop the similarity test and replace it with a simple "causal link". A broadening of copyright that will hurt creativity from now on.

I didn't read anywhere that their complain was training (there are many complaint about training though). But Sora2 is creating basically infringing videos and that seems to be there issue. The whole reason training on copyrighted works get brought up is because it then allows the models to create infringing work based on the original. The whole worry about training on One Piece is that they can then use it to create videos with characters from One Piece or based on One Piece, which would be infringement. I

No, it's very much just the fact that they are ripping off the characters.

Copyright in Japan is interesting. There is a lot of unlicensed use of characters in unofficial books, often but not always pornographic. There is also a lot of non-commercial fan art use. It's all tolerated, even if it is technically infringing.

Supposedly there is a doctrine in Japan called shiteki-fukusei which allows private duplication of television content for personal use, so no, VCRs or DVRs are not illegal. However this isn't really the same as the concept of "fair use" in the context of creating derivative works, which is the issue here.

And this is why patents and copyrights are for a limited time, after which they enter the public domain and are free for anybody to use. Yes, the Bern Convention extends copyrights to an unreasonable duration, but even they eventually end. You may or may not agree that morally what the AI companies are doing when they use copyrighted material without permission and without paying royalties is theft, but that's what the law says, and that law should be enforced.

Ever hear of clean room reverse engineering? Perfectly legal, and the only current legal way to replicate someone else's protected work. OpenAI has decided that was too much work; which is true since it would probably take 100 years to do what they did in a few by simply copying everything from everyone without permission.

Why make this about me? I asked a legit question. It is easy to find anything online, and see the original. Most of it is officially from the source, but there are a lot of "piracy" sites too. So if infringement was the goal, it would be easier to just get the original. It is fast, free and perfect fidelity. On the other hand generative AI will not replicate works closely, it costs money and is slow. Imagine generating bootleg Harry Potter, it would not work out, it would cost a lot, and take a long time. S

Image generators are not selling copyright material, but they are selling an easy way to produce copyright material. It's like they are selling an advanced version of photoshop, but instead of drawing a perfect circle like photo shop allows, it draws much easier and faster. These productions should not be subject to copyright law whatsoever as they are only produced by the tool because of the user's actions. The copyright would still come into play when users use or sell that material.

A good take, I agree. Let's say we generate 100 pics privately, and as most gen AI images, only see them once and promptly move on. Is this private use infringing? Even if it doesn't look substantially like anything in the training set?

I am going to use a bad analogy, you can buy a hammer and use it as a weapon - but you can also buy a firearm designed to be a weapon. I will argue that current AI training is more like the firearm with which the user can shoot themselves in the foot and bam: Trademark infringement lawyers are knocking at the door.

The ships and lives at Pearl Harbor were irreplaceable treasures too. AI is too important for the world, Japan can't expect to make money off manga/anime forever. Americans made the first transistor, but the world makes them. We didn't even try to block that. At some point an invention, after the inventor has squeezed a reasonable benefit, becomes public domain (and that means Japanese too benefit from it). The reason is all inventions are based on prior inventions of others worldwide in some way.
