Kenjiro Tsuda, the acclaimed Japanese voice actor behind iconic anime characters like Seto Kaiba in Yu-Gi-Oh! and Kento Nanami in Jujutsu Kaisen, has reportedly taken legal action against TikTok over the alleged unauthorized use of an AI-generated replica of his voice.
According to reports emerging from Japan, Tsuda filed a lawsuit at the Tokyo District Court accusing the platform of allowing monetized content creators to distribute videos narrated with an AI voice that closely imitates his signature tone and delivery.
The lawsuit claims that one TikTok account uploaded nearly 200 videos using the AI-generated narration. Tsuda’s legal team alleges that the account profited from the content, reportedly earning hundreds of thousands of yen monthly through monetization.
Lawyers representing the veteran actor argue that the AI voice imitation violates his publicity rights and unfairly exploits the years of work and recognition attached to his vocal identity. They also warned that unchecked AI replication could create long-term risks for voice actors and performers whose likenesses can now be digitally reproduced without consent.
TikTok’s Japanese operator has reportedly denied the claims, arguing that the narration in question was merely a “generic male voice” and not a direct reproduction of Tsuda’s performance or identity.
The lawsuit is already being viewed as a potentially landmark case in Japan’s growing conversation around artificial intelligence and intellectual property. As generative AI tools become more accessible, entertainment industries worldwide are increasingly grappling with questions surrounding consent, compensation, and ownership of digital likenesses.
Kenjiro Tsuda remains one of Japan’s most recognizable voice talents, widely celebrated for his performances in major anime franchises including Yu-Gi-Oh!, Jujutsu Kaisen, Tokyo Revengers, Chainsaw Man, and Attack on Titan. His deep, commanding voice has become a defining part of many fan-favorite characters over the years.
