Tochigi robbery-murder: Police probe SNS 'dark job' link in high school student case
NHK reports that a male high school student, arrested as the perpetrator in a Tochigi Prefecture robbery-murder, initially applied for an unregulated part-time job via social media, leading to the recruitment of accomplices and contact with suspected instigators.

Japanese police are investigating the origins of a violent robbery-murder in Uwakawa Town, Tochigi Prefecture, after determining that the crime may have been triggered by a high school student’s application for an illegal 'dark job' through social media. The incident, which resulted in the death and injury of a family of three, has led to the arrest of six individuals, including the student identified as the physical perpetrator.
According to reporting by NHK, the arrested male high school student initiated contact with other suspects after applying for what is known as a 'yami-baito' or 'dark job'. These terms refer to unregulated or illegal part-time work advertised online, which authorities note can sometimes serve as a gateway to criminal activity. This initial application reportedly served as the catalyst for recruiting three other high school students and establishing communication with a couple suspected of acting as masterminds or instigators.
The investigation has confirmed that the six individuals arrested in connection with the case had no prior acquaintance with the victims. The victims, a family of three, were attacked at their residence in Uwakawa Town. Police are currently examining the extent of involvement of the three additional high school students recruited through the social media channel and the specific roles played by the couple suspected of directing the operation.
While the male high school student has been arrested as the individual who carried out the physical attack, the exact nature of the 'dark job' application and how it directly facilitated the planning of the robbery-murder remains under police review. Authorities are treating the couple suspected of being masterminds with caution, noting that their full involvement and exact roles are still part of the ongoing investigation.
The case highlights the potential dangers of unregulated online job markets, where illegal activities can be disguised as legitimate part-time work. Police continue to gather evidence to determine the full scope of the conspiracy and the motivations behind the recruitment of minors for what has now been classified as a robbery-murder.
