Japanese Publishers Outraged After Distributor Admits Selling Books to Anthropic

A subsidiary of major Japanese book distributor Nippan Group Holdings has admitted to selling large volumes of publications to US artificial intelligence developer Anthropic, sparking significant backlash within the publishing industry. The revelation emerged from internal documents released during a class-action lawsuit filed in August 2024 by authors alleging copyright infringement through unauthorized digitization. These court records identified Nippan Japan as one of several distributors supplying books for Anthropic’s Project Panama.
Following inquiries from the Japan Book Publishers Association, Nippan acknowledged transactions occurring between December 2024 and December 2025 but claimed it did not understand the purchases were intended for AI training purposes. While specific details regarding volume, pricing, and actual usage remain unverified, the incident has drawn sharp criticism from industry executives who view the actions as undermining Japanese publishing culture. The company has been asked to cease supplying materials for such uses.
