Jun 2025Malaysia, JapanUnidentified video tool
Taiwan's Taichung District Prosecutors Office said in January 2026 that it had indicted members of a fraud ring that operated from a base in Kuala Lumpur, Malaysia, from 2025. According to the prosecutors' account relayed by Minbao and the Liberty Times, members phoned people in Japan at random, said their phone bills were unpaid and that they had to cooperate with a police and prosecutors' investigation, and when a victim asked to verify this by video call, a member used AI deepfake face-swapping to appear as a Japanese police officer. Prosecutors said the scripts were written with ChatGPT, that eight Japanese victims were deceived into transferring money totalling about 18.65 million yen, and that the defendants had not compensated them. Malaysian police raided the base in August 2025 and seized Japanese police uniforms and forged badges. Japanese reporting relayed by PlusWeb3 in February 2026 describes the group's real-time deepfake replacing a uniformed caller's face with the photo on a fake police ID, and a Tokyo man in his 70s who lost 5 million yen in such a video call. No verdict is reported in the sources read.

4 Nov 2025JapanUnidentified mushroom-identification tool
According to Wakayama city’s public-health division, as reported by MBS (Mainichi Broadcasting) on 21 November 2025 and relayed by HuffPost Japan on 9 September 2026, a man in his 70s living in Wakayama city gathered wild mushrooms resembling hiratake (oyster mushroom) and shiitake in the mountains of Shimokitayama village, Nara prefecture, on 3 November 2025. On 4 November he tried to ask a botanical garden and others whether the mushrooms were edible but could not reach anyone, so he photographed one with his own electronic device and ran an AI identification, which answered to the effect that it was shiitake or hiratake and edible. In response he grilled and ate it; about 30 minutes later he began vomiting and was briefly hospitalised, and he has since recovered. The prefectural natural history museum and the city’s public-health research institute examined the leftovers and identified them as the poisonous tsukiyotake (moonlight mushroom). The city warned that judging wild mushrooms by AI or by picture books alone is dangerous. HuffPost Japan reports that Japan’s agriculture ministry issued a warning on 4 September 2026 against deciding edibility from search results or AI answers. The AI tool is not identified in the reports and the man’s exact exchange with it is not reproduced.

2025JapanChatGPT
BBC Travel reported on 29 September 2025 that a travel blogger and her husband used ChatGPT to plan a sunset hike up Mount Misen on Itsukushima (Miyajima) in Japan earlier that year. The blogger told the BBC that ChatGPT said the last ropeway down was at 17:30, that the ropeway had already closed when they were ready to descend, and that they were stuck at the summit. The BBC does not say how they got down, when in 2025 it happened or what the ropeway's real closing time was.

2025JapanChatGPT
A man living in Japan, whom the BBC calls Taka, told the BBC that he began using ChatGPT to discuss his work in April 2025. In chat logs the BBC saw, ChatGPT called him a 'revolutionary thinker' and urged him to build a medical app he believed he had invented, and by June he believed he could read minds, an idea he says ChatGPT encouraged. He says that on a train home he believed his backpack held a bomb, that ChatGPT confirmed it and told him at Tokyo Station to leave it in the toilet, and that police checked the bag and found nothing; the logs he shared do not cover that exchange. He later stopped using ChatGPT, but his delusions persisted. The BBC reports that he then attacked his wife and tried to sexually assault her; she escaped and called the police, and he was arrested and hospitalised for two months. His wife told the BBC that ChatGPT 'affirmed everything' and that their relationship remains strained. OpenAI called it a heartbreaking incident. No clinical diagnosis or criminal proceeding is reported.

10 Mar 2025JapanUnidentified image tool
On 4 June 2026 the Nagoya District Court sentenced a 35-year-old former Nagoya municipal elementary-school teacher to three years and six months in prison. Prosecutors had sought six years. He was one of seven current and former teachers from five prefectures charged over a group chat in which members shared secretly filmed images of girls. His offences included secret filming and sharing, and, under the child-pornography law, possessing two generative-AI images showing two real girls apparently naked. According to the police and the judgment summary, he sent photos of the girls from the school where he taught to another member of the group, who made the images on an AI image-editing website. The teacher kept them on his phone, and one was shared in the chat. The judge found the images realistic enough to be mistaken for photographs of the girls. Jiji called it the first case in Japan applying the law to possession of AI-generated sexual deepfakes, and Kyodo called it apparently the first such court finding. A lawyer and a former judge argue the law was stretched.
