Shuto Inomata, a 25-year-old member of the eight-member idol group timelesz, was arrested by the Metropolitan Police Department on September 19 on suspicion of assault. According to investigators, Inomata struck the face of an acquaintance, a woman in her 20s, during an argument inside a car parked at a convenience store in Tokyo’s Koto Ward.
Police say the alleged incident took place on the night of September 18. According to reports, the woman told convenience store staff that she had been hit, and employees and witnesses called emergency services on her behalf. Inomata has reportedly told investigators that their hands “made contact” during the argument, disputing the characterization of a deliberate blow. The Metropolitan Police Department has not released further details as the investigation continues, and no charges have been formally filed at this stage.
News of the arrest broke Friday afternoon and spread quickly across Japanese social media, with many users saying their first instinct was to assume the report was fake given Inomata’s profile as a member of one of the country’s best-known idol acts. As of this writing, timelesz’s agency, STARTO ENTERTAINMENT, has not issued a public statement addressing the arrest or Inomata’s status within the group.
Who is Shuto Inomata?
Inomata joined timelesz in February 2026, becoming a member without going through the years-long “Junior” trainee system that has traditionally served as the entry path into groups under Japan’s top idol agency. Unlike most of his groupmates, he was reportedly recruited from outside that usual pipeline, a move fans and commentators at the time framed as part of an effort to bring new faces into a group carrying the legacy of the agency’s decades-old talent system.
timelesz is the rebranded name of the group formerly known as Sexy Zone, one of the agency’s longest-running idol units, which adopted its new name and an expanded lineup as part of a broader relaunch. Inomata’s addition earlier this year was among the highest-profile changes to come out of that relaunch, and he had performed with the group’s full eight-member lineup at live shows since joining.
Even before Friday’s arrest, Inomata had drawn some scrutiny online. Around the time his membership was announced, photos purportedly showing him with a former girlfriend circulated on social media, which a number of fans pointed to afterward as an early sign of trouble. In the hours after the arrest, an edit to his Wikipedia page claiming he had already been removed from the group also circulated on social media, though no such announcement has actually been made by the agency.
Reaction and What Comes Next
The arrest has generated heavy discussion online, with commenters expressing shock that a member of such a prominent group would be implicated in a criminal case, while others noted that idols affiliated with major Japanese agencies rarely resume full promotional activity after an arrest of this kind. No decision on Inomata’s participation in upcoming timelesz activities has been announced publicly.
Investigators are continuing to question Inomata and the woman involved as they work to establish the full circumstances of the altercation. JAPUZI will update this story as more information becomes available.
Author’s Comment
I’ll admit it: my first reaction to this headline was the same as half of Japanese Twitter — I actually checked whether it was a fake account. A newly added member of one of STARTO’s flagship groups getting arrested over an alleged parking-lot altercation just months after debuting is the kind of plot twist you can’t script. Japan’s idol industry loves selling the idea that its stars are chosen for character as much as looks, and stories like this are an uncomfortable reminder that a debut isn’t a background check. I have zero interest in playing judge and jury off a police blotter and a rumor-mill Wikipedia edit — that’s what the actual investigation is for. What I will say is that agencies have gotten very good at making scandals quietly disappear, so don’t be surprised if this whole story goes strangely silent within a few weeks.
