Nippan Group Holdings, parent of major wholesaler Nippon Shuppan Hanbai, has admitted to the Japan Book Publishers Association that one of its companies sold a large number of books to US AI firm Anthropic, according to Kyodo News and The Mainichi. The company said a subsidiary sold books to Anthropic for roughly a year from December 2024. In Japan, Kyodo reports, the news landed hard because Nippan sits at the center of the distribution network publishers rely on, and the admission came only after the association pressed the company in writing.

Publishers' concern is not only licensing but the physical fate of the books. Kyodo News and The Mainichi both report growing industry fears that the volumes may have been destroyed after their spines were cut to enable scanning for digital training data. An industry source told Kyodo that "it would be regrettable if the company had sold books knowing they would be used to train AI," stressing that permission from authors and publishers must be obtained before books are supplied for such purposes.

Nippan says it did not know the sales would serve AI training, a defense publishers appear unlikely to accept as sufficient. Kyodo notes the case follows wider anxiety across publishing about AI — ABC News segments carried by Yahoo and Central Oregon Daily this week examine how literary agents and publishers are grappling with AI's impact on the industry. Expect rights bodies to demand clearer consent rules for bulk international sales.

The dispute sits inside a larger contest over who controls books in the AI era. AUTOMATON reports Anthropic's "Project Panama" spanned three continents, while Anthropic simultaneously faced a US class-action over digitizing pirated books — the suit whose filings exposed the Nippan link. Kyodo's related coverage lists stories on AI leaders warning the UN of security risks, showing how quickly AI's content sourcing has become a diplomatic and legal battleground. For devoted readers, the Nippan affair is the rare inside-baseball story — a wholesaler, a spines-cut scanner, and an association letter — that could reshape how bulk book sales to AI companies are policed worldwide.
