Goku's voice actress hates AI clones — her own agency already made an official one
Japan's actors union has just written its first rules for AI voices, and they draw almost exactly the line Nozawa's agency drew two years ago. With Nozawa turning 90 on 25 October, they also say who decides when Goku's voice carries on without her.
Masako Nozawa has voiced Goku since Dragon Ball first aired on Fuji TV on 26 February 1986, and she has now seen AI videos made with her voice without permission. On 15 October 2026 she told NHK what she made of them.
"This is not my voice. Using it without asking is unforgivable. It's the same as stealing, and it makes me angry."
— Masako Nozawa, to NHK (translated from Japanese)
The AI version, she added, might even be a perfect copy, "but it has no heart". The same day, the Japan Actors Union, which represents around 2,600 stage, screen and voice actors, unveiled its first guidelines on generative AI and the human voice. Nozawa sent a video message to the press conference. She isn't weighing in from the sidelines: she is one of the union's vice-presidents.
So it was filed as anime legend versus the machines. It isn't that fight.
The AI Nozawa that already exists
On 7 October 2024, Nozawa's agency, Aoni Production, announced a partnership with the AI voice platform CoeFont, built on vocal data from ten of its actors, Nozawa included. The uses: virtual assistants, robots, medical devices and navigation. One condition did the heavy lifting: Aoni would strictly forbid the voices from actual performances in anime or films. Whether the service has gone live hasn't been confirmed.
So an official AI Nozawa was signed off two years ago. It may read you directions to the station. It may not be Goku.
The voice of Goku already has an AI licence. It just doesn't cover being Goku.
Reddit got there quickly. "She just wants paid, which is fair," read one of the most upvoted replies in a r/technology thread. Her objection isn't to the technology. It's to strangers doing for free what her agency negotiated on her terms.
What the union rules say
The guidelines draw almost exactly the line Aoni drew in 2024, in four points aimed at studios, agencies and platforms. Read next to the CoeFont deal, it looks less like a ban than a set of terms:
- Consent at every stage: separate permission to train on a voice, to build a model of it, and to use the output.
- No buyouts: nobody signs their voice away for good; consent generally runs for a year.
- No AI dubbing: AI shouldn't replace human performers in film and TV dubbing.
- The dead stay off-limits: in principle, no recreated voices of late actors in new work; any exception needs the family's permission.
None of this is law. The guidelines are voluntary, and Japan still has no comprehensive statute on AI and voices. Hence Nozawa's message to ordinary users: posting a performer's voice online without permission is a problem in itself.
In October 2024, Ryusei Nakao, the voice of Frieza, fronted the No More Unauthorized Generative AI campaign after finding his own voice on sale without his consent. The last time Goku and Frieza fought on the same side, the universe was at stake.

Who gets to say yes
Nozawa turns 90 on 25 October and is still Goku. Toei owns the character. The voice is a different matter, and for the first time there's a written answer to the question nobody enjoys asking about a performer her age: who decides when that voice carries on without her. Under the union's rules, she does now, and her family does later.
That leaves two ways this goes. Goku stays a human performance for as long as there's a human to give it, or he becomes the first anime lead voiced by a licensed AI, with consent from the people Nozawa chose. Either way, it won't be a fan with a voice model and a YouTube channel.
