AI pirate translation: a Murakami novel was online within 4 hours

On July 3, 2026, Haruki Murakami's new book came out in Japan, and within four hours a pirate translation of it into Chinese, done entirely by AI, was already circulating online. The story, reported by the Japanese magazine Courrier Japon and picked up this week in the Publishing Perspectives news roundup, is not just another piracy story. It shows how short the gap has become between a book coming out in one language and a version of it in another, when someone wants that version badly enough.

If you're an author thinking about translation, there are two things here worth noticing. One is about your rights. The other is about why this happened to this particular book.

What exactly happened

According to the report, Chinese readers of Murakami are used to waiting more than a year for the official translation of a new book of his to arrive. This time that didn't happen.

A 21-year-old literature student from a university in Nanjing, whom the magazine identifies by a pseudonym, wrote his own program that fed the book into the Chinese language model DeepSeek. The program split the text into short passages, left some overlap between one passage and the next so the context wouldn't break, and built a list of names and terms as it went so they would stay consistent. At the end it went over the whole text once more and checked it.

Four hours after the book came out in Japan, the translation was uploaded to an online pirate library and to social media. According to the article, no person read it before that. The cost, according to the same report: 13 yuan, about $1.90, for using the model.

On the Chinese review site Douban, readers were surprised by the quality, and asked out loud what was left for a human translator to do.

Why it's a pirate translation, even if it's good

Because the right to translate a book doesn't belong to whoever is able to translate it. It belongs to whoever holds the copyright: the author, or the publisher that bought that right from them. We wrote about this in detail in who owns the translation rights to a book.

That's true when the translation is done for free, when it's done out of love for the book, and when it's done by a machine. The fact that the technology is cheap doesn't change whose right it is.

And there's one more point here, a less legal one. A translation nobody read before it was published is a translation nobody stands behind. If a character's name got garbled halfway through, if an ironic line came out earnest, if a joke vanished, there's no one to fix it. And the Chinese reader who read that version will remember Murakami through it.

Why it happened to this book

Because there was a large audience waiting, and it had no official version. That's the whole secret.

A pirate translation fills a gap. It shows up where there is demand and no supply. A famous author's book, which millions of readers in another language know has come out and can't read for another year, is exactly that gap.

For most authors the situation is the reverse. There aren't millions of readers waiting. Nobody in another language knows the book exists, so nobody will bother translating it without permission. The problem for most authors isn't that someone will steal their book. It's that nobody will find it.

What an ordinary author can take from this

Three things, no drama.

The time between languages has shrunk. A translation of a long book used to be a project of months, and in that time a book could drop out of the headlines. Today a first draft can be ready very quickly. That doesn't mean it's ready for readers, but it changes the math on when it's worth starting.

An official version is your strongest protection. If you have readers in another language, or signs that they're on the way, a translated version of your own, one you checked and stand behind, leaves less room for someone else's version. And even when a version like that exists, readers know where the real book is.

It's worth knowing how to request a takedown. If you ever find your book in a language you didn't approve, document where it is and contact the site or store hosting it. Most large platforms have a proper form for reporting copyright infringement. If you have a publisher, that's their job.

What this story doesn't say

It doesn't say that machine translation, with no person reading it, is enough for a book. The readers on Douban were impressed, but none of them could know what got lost along the way, because none of them read the original and the translation side by side.

And that difference matters to you in particular. Murakami's book will survive one pirate translation. A first book by an unknown author is judged by the first version the reader meets, and it doesn't always get a second chance.
