Yuki Kaji, the voice actor behind Shinji Ikari in Neon Genesis Evangelion, has publicly condemned AI voice cloning technology, calling the practice "heartbreaking" and demanding intervention from the Japanese government.
Kaji's statement reflects growing anxiety within the voice acting community over synthetic voice technology that can replicate performer vocal patterns without consent. The actor expressed frustration that meaningful action remains absent, saying it would be nice if "somebody did something, for once." His frustration points to a regulatory vacuum where AI companies continue deploying voice cloning tools while entertainment industry professionals lack legal protections.
The controversy extends beyond individual actors. Japan's voice acting industry, a cornerstone of anime production and localization, faces genuine disruption from generative AI. Unlike Western markets with stronger union representation through SAG-AFTRA, Japanese voice actors operate with fewer contractual safeguards against synthetic replacement. AI companies have already demonstrated the ability to clone voices from archived recordings, creating perfect replicas without performer permission or compensation.
Kaji's position carries weight. As the iconic lead voice in one of anime's most influential series, his statement signals that even A-list talent cannot assume protection from voice cloning. The concern transcends anime. Japanese game developers, who employ thousands of voice actors for RPGs, visual novels, and action games, could theoretically replace entire voice casts with synthetic alternatives at minimal cost.
The call for government intervention suggests voice actors view market forces alone as insufficient. Without regulatory frameworks establishing ownership rights over vocal biometrics and consent requirements for voice cloning, the technology will likely proliferate unchecked. South Korea and parts of the EU have begun exploring voice cloning regulations, but Japan has taken minimal action despite being a global center for voice performance talent.
Kaji's statement arrives as other entertainment figures internationally have raised similar alarms. The difference here: Japan's
