Recently, Japanese second-hand bookstores have witnessed an unusual sales boom, with large quantities of books being purchased in bulk by the ton, suspected to be sent overseas to AI companies for scanning and subsequent destruction. Multiple bookstores report daily sales reaching hundreds of copies, with sales surging up to five times the usual amount during certain periods, with most orders directed to a logistics center in Okayama Prefecture. Japanese TV recordings show that an order for 50 tons of books has been shipped to the United States for scanning and processing by Anthropic. The purchased categories focus on knowledge-intensive texts such as philosophy, history, medicine, and law, in stark contrast to best-selling genres like novels and comics. Bookstore owners have mixed feelings about the sales surge, expressing concerns about the long-term impact on inventory and the circulation of rare editions. Current Japanese law permits the scanning of books for AI learning purposes, but this bulk operation, conducted without consulting authors, has sparked copyright controversies.
