Can You Sell Chainsaw Man Merch on Etsy? The 'Japan Allows Fan Works' Myth

If you sell anime merch on Etsy, you have probably heard some version of this: "Japanese publishers don't care about fan works. There's a whole culture of it — Comiket, doujinshi, thousands of artists selling stuff based on Shueisha titles every year. So a Chainsaw Man sticker or a Pochita plush is fine."

It is one of the most confidently repeated claims in the anime-merch corner of Etsy, and it is wrong in a way that gets shops suspended. The short answer: Chainsaw Man is a fully owned, actively licensed property, and Japan's tolerance of doujinshi is a domestic social custom — not a law, not a license, and not something that travels to a Western marketplace. Selling Denji, Pochita, Makima, or a "Chainsaw devil" design on Etsy without a license is copyright infringement plus, in a lot of cases, trademark infringement, and the fact that a similar drawing might survive at a convention table in Tokyo has no bearing on whether Viz Media or Crunchyroll files a complaint against your listing.

Let me walk through exactly why the doujinshi argument falls apart the moment you cross onto Etsy, and what you can actually sell without waiting for a takedown.

What the doujinshi argument actually gets right

Give the myth its due, because the kernel of truth is what makes it so persuasive.

Japan really does have a vast derivative-works culture. Doujinshi — self-published fan comics — are sold openly at conventions, and Comiket alone draws hundreds of thousands of attendees twice a year. Industry estimates put the number of doujin selling events in Japan at roughly a thousand per year. Many rights holders genuinely look the other way, and some, like a number of game companies, publish "derivative work guidelines" that spell out what non-commercial fan activity they will tolerate. The common rationale is that hardcore fans who make doujinshi are free promotion, not competition, and that dragging your most devoted readers into court is a public-relations own goal. Even a sitting prime minister once argued publicly that doujinshi should be treated more like parody than piracy.

So yes: in Japan, a lot of unlicensed fan work exists in a tolerated gray zone. That part is real.

The mistake is reading "tolerated" as "legal," and reading a Japanese convention norm as a rule that applies to a US-based e-commerce platform. Neither leap holds.

Tolerance is not a license — and Japanese law says so plainly

Japan's Copyright Act does not have a broad "fair use" doctrine the way US law does. Instead it uses a closed list of specific exceptions, and unauthorized fan adaptation is not on it. Under Article 27, the author holds the exclusive right to adapt, arrange, transform, or dramatize their work — that is the adaptation right, and a doujinshi built on someone else's characters exercises it without permission. Article 28 extends the original author's rights over derivative works, and Article 20 protects the author's moral right to the integrity of the work. A fan comic that reworks a licensed series can infringe all three at once.

In other words, the reason doujinshi survive is not that they are lawful. It is that rights holders choose, most of the time, not to enforce. That is a discretionary business decision, and it can be switched off without notice.

It has been switched off. In the Pokémon doujinshi incident of 1999, three companies including Nintendo filed a criminal complaint against an artist who was selling an adult doujinshi based on the franchise. Eight days later the Kyoto Prefectural Police arrested her; she was detained for 22 days and fined — over sales of five copies at 600 yen apiece plus roughly a hundred more held for distribution. The tolerance that "everyone knows about" evaporated the instant a rights holder decided the work damaged its brand.

That case is the whole point in miniature. The custom is real, but it lives entirely at the discretion of the owner, and it has never been a defense you can rely on. A Chainsaw Man rights holder who decides your listing crosses a line owes you nothing — least of all the benefit of a convention-hall tradition.

Even if it were legal in Japan, it doesn't cross onto Etsy

Here is the part the myth ignores completely: the doujinshi norm is about a specific place, a specific format, and a specific set of Japanese rights holders. Etsy is none of those things.

Different owners hold the rights you'd actually be answering to. Chainsaw Man was created by Tatsuki Fujimoto and is published by Shueisha, but the rights that matter for a Western Etsy seller are held by different companies. In North America the manga is licensed in English by Viz Media. The anime — animated by studio MAPPA — streams worldwide through Crunchyroll, in more than 200 countries. And Chainsaw Man – The Movie: Reze Arc, which premiered in Japan on September 19, 2025 and rolled out across 80-plus countries days later (with a US theatrical release through Sony Pictures Releasing on October 24, 2025), pulls Sony's distribution muscle into the picture too. None of these companies participate in Comiket's gentlemen's agreement. When Viz or Crunchyroll files an intellectual-property complaint against an Etsy listing, they are enforcing rights they paid for, in a market they actively sell into.

They actively sell the exact merch you'd be competing with. Crunchyroll runs an official Chainsaw Man merchandise store; Viz sells official releases. The "free promotion, not competition" logic that props up doujinshi tolerance collapses when your unlicensed plush is sitting in the same search results as the licensed one. You are no longer a fan filling a gap the owner ignores — you are undercutting a product line the owner is trying to sell.

Etsy runs on its own rules, not Japanese custom. Etsy's intellectual-property policy lets a rights holder report a listing, and Etsy removes reported listings without holding a mini-trial over whether Japanese doujinshi tradition might have excused it. A strike lands on your account. Enough strikes and the shop is gone. The platform never asks whether Comiket would have allowed it.

This is the reusable lesson for any imported-IP niche, and it is the same trap sellers fall into with K-pop photocards or European football crests: a foreign country's tolerance custom is not a license, and it does not follow the product across a border into a US marketplace. We covered the broader version of this in our guide to selling anime, manga, and K-pop merchandise on Etsy.

The three layers stacked on a single Chainsaw Man listing

Strip away the doujinshi argument and here is what your "harmless fan sticker" is actually standing on.

Copyright in the characters and art. Denji, Pochita, Makima, Power, Aki — every character design is an original copyrighted work, and so is every manga panel and anime frame. Redrawing them in your own style does not launder this; a hand-drawn Pochita is a derivative work, and the right to make derivatives belongs to the copyright owner, not to you. "I drew it myself" answers a question nobody asked. It is still built on their character. We break this down in detail in our post on selling fan art on Etsy and the derivative-works rule.

Trademark in the names and logos. "Chainsaw Man" as a title, the stylized logo, and character names function as source identifiers, and rights holders register and protect them for merchandise — apparel, toys, stationery, the whole Etsy aisle. You can see how the checker treats the franchise on our Chainsaw Man trademark guide page. This is a separate claim from copyright, and it is why even a plain-text listing that copies no artwork at all — "Chainsaw Man inspired tee," nothing drawn — can still draw a complaint on the name alone. The same pattern shows up across every big Shueisha title; see our breakdowns for One Piece and Demon Slayer — and the Demon Slayer trademark guide — all of which sit in the same rights structure.

The active-franchise multiplier. A dormant property gets enforced loosely. A property with a movie in theaters in 80 countries and a fresh licensed merch push does not. The Reze Arc film landed in 2025 to a 96% critics' score and a global rollout, which means right now is the worst window to bet on a rights holder not noticing — the licensing program is switched on and the brand-protection budget is funded.

Tags and descriptions are where sellers convict themselves

A point most anime sellers miss: the risk is not only in your title. Etsy's search — and any competent brand-protection scan — reads your tags and descriptions too.

The classic laundered listing has a title like "cute chainsaw puppy sticker" or "sad devil dog art print," carefully avoiding the franchise name up top. Then the tags say chainsaw man, pochita, denji, makima, mappa, reze. Those tags are the confession. You added them because that is what buyers search for — which is exactly the point: they prove the listing trades on the franchise's recognition, not on your original creativity. A full-shop scan that only read titles would miss this; one that reads the whole listing catches it. If the brand name is anywhere in the listing because you wanted the search traffic, treat the listing as exposed.

What you can actually sell

None of this means the anime aisle is closed to you. It means you sell what is yours or what is genuinely resold.

Your own original characters and art. A creepy-cute devil-dog design that is genuinely your own — not Pochita with the serial numbers filed off — is yours to sell. Original horror-manga-style illustration, your own monster designs, your own aesthetic: all fine. The test is whether a fan would recognize it as that character. If the whole appeal is that it reads as Pochita, it is Pochita.

Genuine, unaltered official merch, resold. The first-sale doctrine lets you resell an authentic Chainsaw Man item you legitimately bought — an official Crunchyroll figure, a Viz volume — in its original form. What it does not let you do is manufacture new goods: cutting up an official shirt into a new product, printing an official image onto a blank, or "upcycling" that alters the branded item crosses back into infringement. Our first-sale doctrine guide covers where the line sits.

Fan work, if you keep it off the marketplace. If you want to make a Chainsaw Man piece for a Japanese convention table or to give away, that is between you and the rights holder's tolerance. The moment it becomes a listing on a US commercial platform, you have left the gray zone the doujinshi custom lives in — and stepped into the one place it was never meant to protect.

The doujinshi culture is real, and it is genuinely one of the more fascinating corners of how fandom and copyright coexist. But it is a custom that lives at a Tokyo convention hall, at the pleasure of the rights holder, under a copyright law that technically forbids it. It is not a permission slip, and it does not have your Etsy shop's back.
