Tokyo police arrested three men for their alleged roles in a planned robbery at a precious metals buying office in Shinjuku Ward [1].
The arrests signal a continuing crackdown on organized theft rings in Japan. Authorities are investigating whether the suspects belong to "Tokuryu," a loosely organized, anonymous, and fluid criminal group that coordinates high-stakes crimes through encrypted messaging [1], [3].
Among those detained is 20-year-old Masago Yamaguchi [1]. The suspects were found in possession of police batons and tear gas spray, tools typically used to incapacitate victims and security personnel during a heist [1], [2].
According to investigators, the group targeted a precious metals dealer in Shinjuku to steal valuables [1], [2]. The incident occurred in May 2026 [1]. While these three men were recently apprehended, police had already arrested six other individuals identified as executors in the same case [1].
Some of the suspects are linked to Handa City in Aichi Prefecture [1]. The Metropolitan Police Department is working to determine the full hierarchy of the operation and whether the group had successfully scouted the target location before the intervention [1].
Police said the suspects were wandering the area near the target office when they were intercepted [2]. The investigation remains ongoing as officials seek to identify further accomplices who may have provided logistics, or intelligence, for the planned crime [1].
“Police are investigating whether the suspects belong to "Tokuryu," a loosely organized, anonymous, and fluid criminal group.”
The involvement of 'Tokuryu' groups represents a shift in Japanese organized crime, moving away from the rigid hierarchy of traditional Yakuza toward decentralized networks. By recruiting young 'executors' via social media for specific tasks, these groups minimize the risk of total network collapse if one cell is captured. The arrest of nine total suspects in this single plot underscores the scale of coordination required for these modern heists.
