According to his complaint, as reported by Jiji Press, Nikkei and the Asahi Shimbun, an account run by an unidentified person posted at least 188 short videos on urban legends, the occult and trivia between July 2024 and September 2025, narrated in a voice modelled on his; the account had about 210,000 followers, videos averaged 1.47 million views, and his side says the poster earned 500,000 to 750,000 yen a month from TikTok's view-based payments. Viewers commented that the voice sounded like him. He argues this infringes his right of publicity and the Unfair Competition Prevention Act by passing the videos off as his narration. TikTok's operator denies that the voice is shown to be his, calls it a generic male voice, says the account and videos were deleted after the suit was filed and asks for dismissal; the poster reportedly said online that the voice was made by training AI on a friend's voice.
