Tokyo Metropolitan Police have arrested Hikaru Sato (佐藤光), 25, who was known as "Uni" in the "Toyoko" area beside the Toho building in Shinjuku's Kabukicho district, on suspicion of filming an obscene video of a high school girl. The Sankei Shimbun reported that the Juvenile Development Division made the arrest on suspicion of violating the Child Pornography Prohibition Act, and described Sato as a resident of Shinjuku with no known occupation.

He is suspected of filming the girl with his smartphone at a hotel in Kabukicho in November 2025 and saving the video. The Sankei Shimbun gave the date as the evening of November 23 and described the girl as a 17-year-old high school student; Livedoor News said she was 16, and Nippon TV said she was 16 at the time. [ 1 , 3 , 6 ]
According to Livedoor News, the video shows the girl appearing drunk and records Sato saying cough medicine "is not bad for the body" as he gets her to take pills; the outlet said the offence is believed to have taken place during an overdose. Nippon TV, citing investigators, said the phone seized by police shows him holding about six pills in his hand and trying to get her to take them, with audio such as "OK, let's go. Take them." [ 1 , 3 ]
The case came to light in February 2026 during a street-guidance sweep in Toyoko, when officers stopped Sato and the girl as they walked from a hotel district. Nippon TV reported that he told officers he had the approval of the girl's parents and that they bathed together but did not have sex. Officers who checked his phone found the video in a hidden folder, the broadcaster said. [ 1 , 3 ]
Sato has admitted the allegation, according to the reports. Nippon TV said he told police he filmed it "while overdosing at the hotel", that he knew she was 16 and that he knew it was illegal, but that spending a long time in Kabukicho had weakened his sense of ethics and risk management. The Sankei Shimbun reported a similar statement. [ 3 , 6 ]
Sato began going to Toyoko about five years ago, according to Livedoor News and the Sankei Shimbun. The Sankei Shimbun said he streamed the voices of young people gathered there on an internet programme, and Livedoor News said some girls had called him "the emperor of Toyoko". [ 1 , 6 ]
