Japanese used-book sellers reported a bulk-order surge from around August 2026, with some days’ sales about five times normal. Separately, records show over 50 tons of “Japanese books” shipped to the US, but do not link that cargo to the orders or confirm AI training.
NNN reported that orders came through multiple buyer accounts at different online stores and that the shipments it examined were headed to one logistics center in Okayama Prefecture; its operator did not answer questions. A Tokyo bookseller said recent bulk orders focused on philosophy, history, political history, medicine, law and Edo-period books, rather than novels and comics. No buyer has been publicly identified.
Sayari export records name a group company of a major Japanese publishing distributor, but not the final recipient or any link to Okayama. The 50-plus tons would equal about 100,000 books only at an assumed average of 500 grams each; that is an estimate, not a confirmed count. AI training and scanning in Japan remain unconfirmed. Separate U.S. litigation and reporting allege Anthropic acquired books for destructive scanning, with no established link to these purchases. Japan's Copyright Act permits some information-analysis uses but excludes uses that unreasonably prejudice copyright holders; the article identified no Japanese court ruling on this issue.
