The Tokyo District Court dismissed a lawsuit filed by voice actor Kenjiro Tsuda against TikTok regarding AI-generated voice cloning because the offending account was deleted. However, the court established a significant legal precedent by ruling that a human voice is protected under the right of publicity, potentially impacting future AI-related intellectual property litigation.
This ruling provides a critical legal foundation for talent and studios seeking to protect intellectual property against generative AI exploitation. By extending the right of publicity to vocal traits, the court has closed a significant loophole in Japanese law that previously focused only on names and likenesses. For the streaming and gaming sectors, this creates a clear path for litigation against unauthorized AI-generated content that mimics high-value voice talent. The decision aligns with recent Japanese Ministry of Justice reports suggesting broader legal protections for digital identity. Watch for whether this precedent leads to new licensing frameworks for AI voice models in the Japanese market.
The legal scrutiny of TikTok and Instagram Reels ads continues to grow as regulators examine platform accountability for content and user data. Similar efforts to protect digital likeness are currently moving through the U.S. legislative process. As the industry grapples with these challenges, AI voice cloning deepfakes have become increasingly easy to produce, heightening the urgency for such legal protections. This Tokyo court ruling serves as a landmark case for international intellectual property standards. Meanwhile, German voice actors strike over similar concerns regarding unauthorized AI training.
A Tokyo District Court has ruled that human voices are protected under the right of publicity, marking a legal first in Japan. The decision, stemming from a lawsuit by voice actor Kenjiro Tsuda, establishes that vocal characteristics symbolize personality, providing a vital legal framework for protecting talent against unauthorized generative AI exploitation.
The court ruled that a person's voice symbolizes their personality and that unauthorized use of a voice constitutes an infringement of the right of publicity, similar to portrait rights.
The lawsuit involved voice actor Kenjiro Tsuda, who identified 188 videos using his AI-cloned voice.
The claim against TikTok was dismissed because the specific account responsible for the offending videos had already been deleted.
According to the lawsuit, the videos using Kenjiro Tsuda's AI-cloned voice generated up to 750,000 yen in monthly revenue.
