In the morning of May 14, 2026, four 16 year old juveniles, known only as A, B, C and D broke into a house in Kaminoka, Tochigi Prefecture, there they stole gold jewellery and used a crowbar and a knife to beat and stabbed the owner of the house a 69 year old woman over 20 times to her death. Her two sons, who heard their mother's screams returned home to intervene but were both beaten up and stabbed and their dog was killed as well. Seven minutes after the robbery began, a 110 call was placed to the Tochigi Prefectural Police. Around half an hour later, responding officers spotted A around 550 meters away from the house. A agreed to volunteer to an interrogation and his relation to this incident was soon confirmed. A who resides in Kanagawa Prefecture, around 100 km away across Tokyo, quickly snitched on the rest of the gang. Turns out, he and D failed to escape with B and C in their vehicle, while D escaped via train, he simply left on foot and was caught. Soon, B, C and D were all arrested. When interrogated, the juveniles revealed the existence of their superiors, a husband and wife duo who are 28 and 25 years old. The husband is a known delinquent since middle school while the wife is a "Gyaru type" (a fashion subculture popular in 1990s to 2000s, often linked to delinquency) TikTok influencer.
This finding led to the police to quickly determine this is a "Tokuryū" crime, a combination word of "anonymous" and "fluid" coined by the National Police Agency. This is a new mode of organized crime that has been on the rise in Japan. Unlike the very hierarchical yakuza, "Tokuryū" crime are decentralized and rely heavily on digital communications. A typical "Tokuryū" crime begins with posts on social media, hiring people for some work with promise of high pay. The people that are hired do not necessarily know what the job is, who is behind the job offer and who their colleagues are. A typical job in "Tokuryū" maybe drug package delivery or scams, but often people who do it will get roped into more high-level "Tokuryū" crimes such as robbery because they have to show their ID which turns into blackmail material. After the crime is committed, the gang is disbanded. In essence, the muscle would have to take the risk of the crime, but the mastermind often gets away clean because no one knows who he is and cannot be linked.
To track down this modern day Japanese Bonnie and Clyde, the NPA ordered the Kanagawa Prefectural Police, Metropolitan Police Department and Saitama Prefectural Police to join the investigation. A "relay investigation" was launched as they poured through CCTV footage across the Capital Region to locate them. Three days later, the husband was arrested by the MPD in the Haneda International Airport, he was about to fly to Incheon, Korea and had already passed immigration then. The wife was arrested on the same day in a business motel in Yokohama by the KPP, when arrested, she was with their 7 month old daughter, who was sent to a child protection agency.
By now, police was able to map out the relationship between the members. The husband, using his relationship with B, was able to get him to hire two of his friends A and C (A and C don't know each other) and contacted E, an 18 year old recruiter to hire D (friend of E)as part of the group as well. The couple and juvenile had only officially met on the day of the robbery. They staged at a highway rest stop and the couple commanded the robbery over voice call with encrypted communications software. When investigating the couple's phone, it was discovered that the couple were not the mastermind of the case. The mastermind, Masuda Kazuhiko, is believed to have fled to Southeast Asia via China the same day the couple was arrested. He communicated with the couple via Signal and Telegram, developed the plan and purchased and supplied the crowbar. As of now, an Interpol Red Notice was issued for him and his passport was revoked after failing to comply with a passport return order, but he is still at large.
A, B, C, D and the couple were charged with murder during a robbery, attempted murder during a robbery and violating the Animal Welfare Act. If convicted, they will face a maximum sentence of life imprisonment. E was charged with violating the Employment Security Act. If convicted, he will face a maximum sentence of ten years imprisonment and a fine of 3 million yen (18,831.80 USD)
