Japanese media groups Nikkei and Asahi Shimbun jointly sue Perplexity in Tokyo, alleging the AI startup “copied and stored” their articles without permission

The publishers say the company illegally ‘copied and stored article content’  —  Two of Japan's largest media groups …

Financial Times

Context & Ripple Effects

The suit follows Yomiuri Shimbun’s recent case against Perplexity over alleged unauthorized use of news content, extending the dispute from one Japanese publisher to two more major media groups.

It also builds on earlier reporting that Perplexity’s Pages feature reproduced publishers’ work with inadequate attribution, while Japan’s copyright framework had already drawn creator concerns over broad AI uses of protected material.

First-order effects

  • Nikkei and Asahi Shimbun put Perplexity’s handling of their articles before a Tokyo court, forcing the startup to answer allegations that it copied and stored their material without permission.
  • The case gives the publishers a direct mechanism to challenge the alleged use and preservation of their reporting, rather than relying solely on requests or public criticism.

Second-order effects

  • The clustered Japanese claims increase pressure on Perplexity to clarify or alter how it obtains, retains, and presents publisher content in that market.
  • Other publishers can treat the earlier reports of near-verbatim story reproduction and the new suits as a shared fact pattern, strengthening their leverage for either litigation or commercial terms.

Third-order effects

  • If courts or settlements establish workable boundaries around copying and storage, AI search products may increasingly need licensed-content arrangements rather than relying on broad access to web-published journalism.
  • The dispute tests whether Japan’s AI-friendly copyright posture can coexist with enforceable publisher control over news archives—a tension likely to shape content-commercialization models, though the legal outcome remains unresolved.

The trend: Publisher challenges to AI search are moving from objections over attribution toward litigation over the copying, retention, and commercialization of news content.
