The Japan Actors Union (Nippon Haiyū Rengō), representing around 2,600 actors and voice actors, published guidelines on October 15, 2026, regarding the use of generative AI for voices. The rules require prior written consent at every stage — learning, generation, and use — and in principle prohibit the replication of deceased persons' voices without prior authorization.
What the guidelines establish
The guidelines treat AI-generated voice use as a new form of performance, requiring adequate compensation beyond normal fees. Blanket buyout contracts are discouraged, and consent generally lasts a maximum of one year. There are also rules for dubbing and multilingual use.
In the same context, Masako Nozawa, the legendary voice of Son Goku in Dragon Ball, told NHK that the unauthorized use of her voice in AI videos is “unforgivable” and equivalent to “theft.” She stressed that AI copies may sound identical but “have no heart.”
Why it matters
The measure comes amid the growth of seiyuu voice clones on social media and AI tools. The guidelines lack the force of law but seek to create an industry standard for anime, games, and entertainment in Japan, protecting performers while guiding companies.
