Tsuda Kenjiro voice deepfake — Oct 2026

Voice actor Tsuda Kenjiro successfully challenged the unauthorized use of his likeness after a TikTok account utilized an AI-generated clone of his voice to narrate videos. The case highlights the growing legal recognition of vocal identity as a protected asset against synthetic media exploitation.

What happened

A TikTok account holder utilized AI technology to create a voice clone that closely mimicked Tsuda Kenjiro’s distinct, low-pitched voice. This synthetic voice was used to narrate a series of videos focused on ghost stories and conspiracy theories without the actor's permission.

Tsuda Kenjiro initiated legal action against the account holder, leading to a ruling by the Tokyo District Court. The court determined that the actor's voice possesses economic value and is legally protected under the "right of publicity." This ruling serves as a significant legal precedent in Japan, where unauthorized AI-generated content—including the theft of celebrity voices and portrait rights—has become increasingly prevalent. The incident underscores the necessity for strict consent protocols regarding the learning, generation, and commercial distribution of AI-synthesized vocal data.
