Tokyo District Court recognizes voice as protected personality right

A Tokyo District Court ruling on September 30, 2026, has established that a person's voice can be protected under publicity rights as a ‘symbol of individual personality’. The decision arose from a lawsuit filed by voice actor Kenjiro Tsuda, who sought the removal of unauthorized videos on TikTok that utilized generative AI to mimic his voice.

While the specific claim was dismissed because the content had already been deleted, the court's legal reasoning carries significant weight. The ruling suggests that the commercial value derived from a person's unique vocal characteristics—developed through training, emotional nuance, and performance—is a protectable interest. This comes amid growing concerns regarding generative AI's ability to produce unauthorized vocal clones that can be used for advertisements or social media content without the original speaker's consent or knowledge.
