00:00Cosplay involves dressing up and portraying characters from anime, manga, video games,
00:05or movies. At first glance, copying the appearance of a copyrighted character might seem illegal.
00:10Technically, it reproduces a protected work. However, in practice, amateur cosplayers are
00:15rarely prosecuted, while the sale of AI-generated images has begun to be punished. In this video,
00:20we explore the legal reasons behind this difference. We will discuss the laws in Japan,
00:25where cosplay is deeply rooted, the rules in countries such as the United States and Europe,
00:30and recent cases of generative AI that have led to arrests. First of all, it is important to
00:35understand that copyright protects the specific expressions of a work, the script of a film,
00:40the original drawing of a character, the music, not abstract ideas. An anime character can be
00:45highly protected if it has a distinctive and recurring design. Legally, a character's costume
00:50is itself a derivative work. You reproduce the character's clothing, colors, and still image.
00:55In general terms, creating and distributing derivative works without the owner's permission
00:59may infringe copyright law. For example, printing and selling posters featuring anime characters
01:05without authorization constitutes an illegal business. However, amateur cosplay is different.
01:10It is a physical recreation, often done on a non-profit basis and in amateur contexts.
01:15In addition, rights holders sometimes consider cosplay to be free advertising for their brand,
01:20which influences how they react. Reproduction vs. Transformation
01:24When a cosplayer reproduces a character, it could be considered copying. But in many countries,
01:29there is the notion of transformative use, especially in the US, that can protect cosplay.
01:34In the US, for example, it is argued that cosplay is transformative because it does not seek to
01:39replace the original work but to pay homage to it. Non-commercial nature
01:43A key factor is whether or not cosplay is a commercial activity. In Japan, and also in practice in other
01:49jurisdictions, it is generally accepted that someone who dresses up as a hobby and does not receive
01:54payment is not a target for the authorities. If the cosplayer makes a living by selling photos,
01:59appearing at events, or promoting products, that changes things. History of Tolerance
02:03Japan has a long tradition of fan art, digenshi, cosplay, and fan fiction being tolerated as long as
02:09they do not harm the rights holder. Our anime companies often see cosplay as a form of free advertising.
02:15In fact, it has been pointed out that cosplay functions as free advertising that enhances
02:20the value of the original product, making it less attractive for creators to initiate lawsuits.
02:25In Japan, cosplay is an important cultural expression. It has become a multi-million
02:30dollar industry at both local and international conventions. This led the Japanese government to
02:35consider clarifying the copyright rules for cosplay. However, the official goal has not been to crack
02:40down on fans, but rather to regulate professionals and ensure that cosplay benefits everyone.
02:45Legal sources express it this way, Japan emphasized that the new measures would only apply in cases
02:50of profit, that is, to professional cosplayers who receive payment for their appearances.
02:55In summary, the position in Japan has been, if a cosplayer attends a convention as a hobby and
03:00without earning money, copyright law does not seek to punish that activity. There is consensus that
03:05in such cases, Japanese copyright laws are not being broken. If a cosplayer sells photos, merchandise,
03:11or commercial agreements using someone else's character, then there could be a possible violation.
03:16For example, attending paid events dressed as a character can be considered profit from someone
03:21else's work. The Japanese government has publicly clarified that it seeks to protect cosplay culture,
03:26not eliminate it. It has been said that cosplay is an important manifestation of Japanese culture
03:31and that there is no desire to affect this creative industry with excessive regulations.
03:35Therefore, changes are being studied to clarify permitted cases, facilitate licensing, and only
03:41penalize commercial use without permission. In other words, only professional cosplayers could be
03:46affected, and even then, it is insisted that the laws will not be as restrictive as feared.
03:51In practice, Japanese cosplayers who are not seeking profit continue to enjoy great freedom.
03:56The situation varies in other countries, but they share some commonalities. United States,
04:01there, the fair use system can protect cosplayers. Although there is no guarantee, many judges would
04:06consider cosplay to be transformative and not commercially competitive with the original work.
04:11In addition, rights holders often view cosplay as free publicity and do not usually sue for it.
04:16It has been documented that the lack of copyright litigation against cosplayers is due to several
04:21factors. Creators appreciate the free promotion, do not want to upset their fans,
04:25and suing would be difficult and counterproductive. Even Disney is cited as an example,
04:30which could take action against a costume seller, but usually avoid suing a famous
04:34cosplayer directly so as not to generate a bad image. In general, except for clear-cut cases,
04:40e.g., a cosplayer selling exact replicas of registered costumes, as demonstrated by the
04:45example of Barney costumes in the US, cosplay has been met with greater tolerance.
04:50Europe, European law is stricter, there is no broad fair use, but there are almost no known cases of
04:55lawsuits over cosplay. In many countries, there is an exception for private use or small reproductions,
05:01but what is really decisive is the cultural attitude. As in Japan, cosplay is considered
05:06part of pop culture and is not usually prosecuted except in cases of clear abuse. In short, cosplayers
05:12in the West benefit from similar factors, transformative use, lack of serious commercial harm,
05:17and appreciation from the creators. Courts find it difficult to convict an amateur for dressing up,
05:22while creators focus their energy on more harmful infringements. No profit motive,
05:26laws focus on punishing commercial use only. Japanese authorities insist that only cosplay
05:32for profit will be punished. Free publicity, cosplay raises the visibility of a franchise.
05:37That is why it is argued that cosplay is free publicity that enhances the value of the original
05:42product, reducing the willingness to sue. Transformative nature, wearing a costume and
05:46acting like a character is seen as a use different from the original medium. Many legal experts believe
05:51that this transformation strengthens the defense of fair use in the US. Practical difficulty,
05:56proving infringement in cosplay is complex. The copied object is a character, not a specific text or
06:02image, and cosplay is often episodic and personal. Courts are wary of setting broad precedents.
06:08Fan culture and cool Japan, the Japanese industry itself promotes cosplay, it even has cosplay ambassadors.
06:14There is a fear that regulating it harshly would spoil global otaku culture,
06:18so laws are applied with caution. These factors explain the general impunity of amateur cosplayers.
06:24Those who do not sell anything usually remain off the legal radar. In contrast,
06:28cases involving AI art have been met with police action. In January 2025, two men in Japan were
06:34arrested for violating copyright law by creating and selling explicit AI-generated posters of popular anime
06:41characters. The photograph shows the AI-generated posters that Japanese police seized in the recent
06:46operation. These images show anime girls, such as Evangelion, and sexual poses created by AI without
06:53authorization. The suspects used AI prompts on copyrighted characters, printed the illustrations,
06:58and sold them at online options. According to the police, one made about 10 million yen
07:03and the other 5.7 million yen selling these posters. Both confessed to the offense after being caught.
07:08This case clearly meets the elements of an infringement. It involved generating derivative
07:13art from protected characters and marketing it without permission. The international press reported
07:18that the defendants have been charged with violating Japan's copyright law for illegally creating and
07:22selling obscene AI-generated posters of popular anime characters. In addition to being illegal, the
07:28content was pornographic, which aggravated the response. In April 2025, another arrest of four people for
07:35selling AI-generated erotic images on suspicion of illegal pornography was even reported. In short,
07:41the sale of derivative digital works is considered piracy. Japanese law protects original art, and
07:46although AI only generates something new, it does so based on millions of pieces of copyrighted data.
07:52When someone prints and sells these images, they are commercially exploiting unlicensed third-party
07:57works. That is why the authorities acted quickly against AI-generators. In light of the above,
08:02we see clear contrasts. Means of exploitation, the cosplayer sells their image or appearances,
08:08if they do so for profit, but does not distribute the original work. In contrast, the AI-generator
08:13sells printed images of the characters. Selling a poster is a direct form of distribution of
08:18copyrighted material, while posing in costume usually generates private or promotional photos.
08:23Manual versus automatic transformation. Cosplay involves craftsmanship, costume-making,
08:28acting, so it can be granted more leeway as personal creative use. AI, on the other hand,
08:34automatically generates content from massive amounts of data, the result can be considered less new,
08:39closer to copying elements of the original work in the final product. Scale and profit. In the case
08:43of AI, there was a clearly defined business, thousands of dollars for posters on the internet.
08:48Many amateur cosplayers do not earn direct income from their cosplay. The laws target the commercial
08:53exploitation of someone else's intellectual property, which is why the profit component was decisive in
08:59the AI arrests. Sensitive content. Some AI cases involve pornography or defamation, such as desecrated
09:06waifus. Although copyright infringement was the charge, the sexual nature of the images intensified
09:11the police and public response. Cosplay does not generally involve illegal content in this sense,
09:16so there are no additional grounds for legal action. In short, amateur cosplayers operate in a
09:21grey area tolerated by the law, while AI generators were in clearly illegal territory,
09:27using protective works to create and sell explicit material. Although in theory any unauthorized
09:32reproduction of a character violates copyright, in practice there are nuances. In Japan and other
09:37jurisdictions, cultural promotion is prioritized and illegal profit is primarily prosecuted. Amateur
09:43cosplayers are seen as fans who enrich the brand, not as pirates to be prosecuted. That is why today
09:48there are no mass complaints against ordinary cosplayers, nor are there laws that expressly criminalize
09:54them. In contrast, recent cases show that the red line is business. Generating explicit art with AI
09:59and selling it without permission crosses legal boundaries. The arrests in January and April 2025
10:05reflect that the authorities are indeed going after those who profit from derivative works,
10:09especially in an automated manner. In conclusion, the current legal and social response favors fan
10:15cosplay, as long as it remains a cultural and non-commercial activity. Even so, it is advisable to
10:21practice cosplay with respect. Many professional cosplayers already ask creators for permission or
10:26invent their own designs to avoid conflicts. Finally, it is important to note that the situation may
10:31evolve. Both Japan and other countries will study laws on AI and cosplay. But today, cosplay does not
10:37lead to jail time, while the illegal sale of AIR does. I would like to leave the following message. As
10:42mentioned, one of the reasons why the men were arrested is for generating explicit content of anime
10:47characters such as those from Evangelion, but there are also many cosplayers who create adult content
10:53dressed up and playing anime characters, so I don't think the laws are being fair to artificial
10:57intelligence. Remember that to learn to draw, you first have to learn to copy, and this is what
11:02artificial intelligence does. However, it is true that if artificial intelligence is allowed to do too
11:08many things, it could end up causing bigger problems. Let me know what you think about this topic in the comments.
