The Tokyo District Court ruled that the unauthorized use of AI‑generated voices that closely resemble a performer’s voice can infringe the performer’s right of publicity. The decision came from a lawsuit filed by well‑known voice actor Kenjiro Tsuda against the operator of TikTok after more than 180 videos used AI‑cloned versions of his voice without permission.
According to newsonjapan.com, the court found that using a performer’s voice to attract customers or viewers without consent could constitute an infringement of publicity rights. The plaintiff, voice actor Kenjiro Tsuda—known for roles in series such as *Jujutsu Kaisen*—identified more than 180 TikTok videos that featured AI‑generated speech sounding like his own.
The ruling emphasized that publicity rights protect the commercial value of a person’s identity, and for the first time in Japan, the court explicitly recognized a voice as part of that protected identity. The decision does not automatically ban all AI voice‑cloning, but it signals that commercial exploitation without permission may be unlawful.
The article notes that modern voice‑cloning applications can generate a convincing replica after a user records roughly 50 predetermined sentences. Some services now offer multilingual voice conversion, allowing a Japanese‑recorded voice to speak English, Chinese, or other languages while retaining the original vocal characteristics.
Developers argue that the technology could benefit professional voice actors by enabling them to produce multilingual content without learning new languages, and it can also help individuals who have lost speech due to illness by recreating their own voice for communication. However, the court’s decision highlights the tension between legitimate uses and unauthorized commercial exploitation.

یہ کیوں اہمیت رکھتا ہے۔
The judgment expands Japan’s publicity‑right framework—traditionally limited to names and facial images—to include vocal identity. As AI voice‑cloning tools become cheaper and require only a few dozen recorded sentences, the ruling creates a legal precedent that could curb large‑scale commercial exploitation of celebrity voices on platforms such as TikTok, YouTube, and emerging metaverse services. It also forces developers to consider consent mechanisms and may legislative updates to address AI‑generated likenesses more broadly.
The precedent may influence how Japanese courts handle future AI‑generated likeness disputes, potentially extending protection to facial deep‑fakes, synthetic text, and other biometric reproductions.
Content platforms will likely need to strengthen verification and takedown procedures for AI‑generated audio, which could increase moderation costs and affect user‑generated content ecosystems.
The ruling could encourage industry groups and voice‑actor unions to negotiate licensing frameworks for AI‑generated voice usage, similar to music‑rights licensing models.
Legislators may feel pressure to codify AI‑generated voice protections, providing clearer guidelines for developers and reducing reliance on case‑by‑case litigation.
