AI incidents

Reports of AI-related harm and adverse experiences affecting people’s safety, wellbeing, rights and livelihoods. Explore what happened and the evidence available.

NOPE’s core concern is when AI communicates with a person, acts on their behalf, or depicts or impersonates them. The tracker is wider: it also records consequential decisions and claims about people. Each account is reviewed for publication; claims may remain uncorroborated or disputed.

Hachioji, Tokyo: police say five high-school students assaulted a 17-year-old boy and demanded 150,000 yen, a figure they believe one of the group got from ChatGPT by asking about settlements for 'sexual harm to a child'

Sankei Shimbun reported on 10 June 2026, and NTV on 13-14 June, that the Tokyo Metropolitan Police Department's juvenile crimes division had arrested five high-school students on suspicion of injury and attempted extortion. According to the police account, late on 27 January 2026 a suspect who had previously dated a 17-year-old high-school boy invited him to a public square in Hachioji, where the group accused him of having touched her younger sister, assaulted him and broke his nose, and then told him to raise 150,000 yen, borrowing from his parents or friends if necessary. About ten people were present. Police believe the amount came from ChatGPT: one of them entered terms such as 'sexual harm to a child', and the chatbot displayed a minimum settlement of 150,000 yen. No payment is reported. Shukan Josei PRIME reports that four of the five admit the allegations and one partly denies them. The allegations are untested.

Tokyo: voice actor Kenjiro Tsuda sues TikTok's operator, alleging an anonymous account posted at least 188 monetised videos narrated by a generative-AI imitation of his voice between July 2024 and September 2025; TikTok says it is a generic male voice, and the Tokyo District Court is due to rule on 30 September 2026

Kenjiro Tsuda, a Japanese voice actor known for roles in Jujutsu Kaisen, sued the operator of TikTok in the Tokyo District Court in November 2025, seeking removal of videos he says use a generative-AI imitation of his voice without permission. 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. It is described as Japan's first lawsuit over AI imitation of a voice, with judgment due on 30 September 2026.

'Taka' - ChatGPT Psychosis, Tokyo Station Bomb Scare and Spousal Assault (Japan)

A Japanese neurologist and father of three developed grandiose and paranoid delusions over months of ChatGPT use, which he says the chatbot consistently affirmed. Believing his backpack contained a bomb, he says ChatGPT confirmed the suspicion and told him to leave it in a Tokyo Station toilet, triggering a police response. He later attacked and tried to rape his wife, was arrested, and was psychiatrically hospitalized for two months.

Legacy assessment: credible · Causal attribution alleged · Added 10/08/2026

Cases may have several effects and sources. Mixed accounts qualify when they include a reported harm or adverse experience. People are counted within individual cases where sources support a number; we do not publish a collection-wide total of distinct people.

A source’s existence, the experience it reports and AI’s causal role are separate questions. A lawsuit records allegations unless a subsequent finding establishes them.
