Highlights
- Japan's AI voice debate gained momentum after calls from veteran voice actors.
- New guidelines could treat unauthorized AI voice copying as a legal infringement.
- Wes Johnson, Jennifer Hale, and other actors have also opposed AI voice cloning without consent.
Veteran Japanese voice actor, Megumi Ogata, has called for stronger legal protections against unauthorized AI voice cloning. Her remarks come as Japan moves closer to recognizing voices as subject to publicity rights, a step that could strengthen legal action against AI-generated voice misuse.
Speaking to TBS News Dig, Ogata, best known as Shinji Ikari in Neon Genesis Evangelion and for roles in Danganronpa and Persona, stated AI-generated voice copies on platforms like TikTok are an issue she cannot turn a blind eye to. Calling her voice a part of her identity, she said it was heartbreaking to hear it used to say things she never agreed to while others profited from it.
She also questioned why Japan, despite calling itself a content superpower, has yet to establish clear rules for protecting voices and other creative works.
Japan Moves Toward AI Voice Protections
According to AUTOMATON, Ogata joined a Ministry of Justice review meeting in May 2026 to discuss unauthorized AI voice generation. She has consistently argued that AI-generated voice copying without consent should be stopped.
That discussion has now led to progress. On July 27, 2026, the Ministry of Justice approved a draft framework that could treat unauthorized AI-generated voice copying and monetized use as an infringement of publicity rights. The proposal would place voices, alongside a person's name and likeness, under legal protection.
The issue has already reached the courts.
Voice actor Kenjiro Tsuda, whose credits include Jujutsu Kaisen's Kento Nanami and Yu-Gi-Oh!'s Seto Kaiba, filed a lawsuit against TikTok operators over AI-generated videos that allegedly copied and monetized his voice. The content reportedly generated ¥500K to 750K ($3.1K to $4.7K USD) per month.
AI Voice Cloning Debate Spreads Across Gaming
Ogata's stance aligns with concerns voiced across the gaming industry.
Voice actor Wes Johnson, known for his work in Bethesda games including The Elder Scrolls and Fallout, noted in a post on X that actors must protect their voices and likenesses, arguing that using an actor's voice for AI-generated mods without consent is wrong. Canadian-American voice actress, Jennifer Hale, has also urged responsible AI policies, while several members of the Baldur's Gate 3 cast criticized AI voice cloning during the 2024 BAFTA Games Awards.
The debate is no longer limited to AI companies. Voice actors are also raising concerns about individual modders and content creators.
For many performers, the central issue is consent, regardless of who creates or profits from the AI-generated voice.
