The Yomiuri Shimbun, one of Japan’s five major daily newspapers, sued Perplexity in Tokyo on 7 August 2025, seeking about ¥2.2 billion in damages. It says Perplexity accessed about 120,000 of its articles between February and June 2025 and that its answer summaries take readers and advertising revenue away from its site.

Why it matters

AI search providers serving Japanese users face a copyright claim from a major publisher. The case will test how far Japan’s training exception covers copying for answers shown to users.
