Japan’s Entertainment Giants Demand OpenAI Stop Using Their Works to Train Sora 2

Government officials warn they may invoke the AI Promotion Act to investigate suspected IP violations.

Overview

  • On October 28, industry group CODA sent a formal request asking OpenAI to immediately halt use of its members’ works for machine learning without prior permission and to address infringement claims related to Sora 2.
  • CODA says it has confirmed that many Sora 2 outputs closely resemble Japanese content, indicating likely use of protected material without authorization and potential violations under Japanese law.
  • The association argues that Japan’s copyright framework generally requires prior permission, asserting that an opt‑out model would not shield OpenAI from liability.
  • CODA’s membership spans Sony’s Aniplex, Bandai Namco, Studio Ghibli, Square Enix, Kadokawa, Shueisha, Cygames, and Toei Animation, signaling coordinated pressure from major rights-holders.
  • OpenAI launched Sora 2 on October 1 to generate short videos, and social platforms quickly filled with clips evoking franchises such as Pokemon, Mario, One Piece, Dragon Ball, and Demon Slayer, while it remains unclear whether Japanese rights-holders were included in any pre‑launch opt‑out outreach.
