A Tokyo court in Japan has reached an important legal decision in a lawsuit filed on the grounds that renowned anime voice actor Kenjiro Tsuda's voice was used without authorization.

A Legal Recognition That Is a First in Japan

This ruling, delivered on Wednesday, marks the first official instance in Japan where the human voice has been placed under legal protection and voice rights have been recognized.

Unauthorized Voice Use on Social Media

Voice actor Kenjiro Tsuda, known for prominent roles such as Kento Nanami in the series Jujutsu Kaisen, had resorted to legal action after an anonymous TikTok account generated unfair profits using an AI clone of his voice.

Reasoning Behind the Court Panel's Decision

Presiding Judge Aya Takahashi stated in the court records that the unauthorized use of the voice constituted a clear violation of personality rights and publicity rights.

Status of the Request to Delete Videos

Although the court ruled that the use of the voice clone was an infringement of rights, it rejected the request for the deletion of the videos because the relevant TikTok account had already been shut down previously.
