Japan Book Publishers Association sends written request for fact confirmation to Nippan over large-scale book sales to Anthropic
日本最大出版取次日贩承认向 Anthropic 大量售书：子公司 2024-12 至 2025-12 发货，累计超 50 吨，出版社协会追问（前情）
The Japan Book Publishers Association (Shokyō) has sent a written document to Nippan Group Holdings requesting confirmation of whether the books sold in large quantities to Anthropic include publications from its approximately 380 member publishers, and asking for relevant details. The association also questioned the legal compliance of Nippan selling books in large quantities to overseas parties without publisher consent, and requested that it stop selling new books for AI learning purposes and state its position on supplying books for AI learning use. The publishing industry had previously harbored concerns about publications being used for AI training, worrying that these books might be used by Anthropic for AI learning.
