Interpol Issues Red Notice for Key Suspect in Tochigi Robbery-Murder
International law enforcement efforts have intensified following the issuance of an Interpol Red Notice for 48-year-old Kazuhiko Masuda. Japanese authorities identified Masuda as the primary suspect in a high-profile robbery and murder that occurred last month in Kaminokawa, Tochigi Prefecture.
The Incident and Investigation
The investigation centers on a violent incident on May 14, which resulted in the death of a 69-year-old woman at her residence. Following extensive inquiries, the Tochigi prefectural police department and the National Police Agency have moved to coordinate with international partners to secure Masuda’s apprehension.

According to investigative sources, the criminal operation was allegedly orchestrated through a highly anonymous messaging application. Masuda is suspected of recruiting Kaito Takemae, 28, to carry out the crime by promising him a significant financial reward. Following the robbery, Kaito Takemae, his 25-year-old wife, Miyu, and four 16-year-old boys were arrested in connection with the case.
International Manhunt
The trail for Masuda led investigators to Narita International Airport, where he departed for China three days after the incident. Authorities believe he has since traveled to Southeast Asia, where he is thought to maintain regional connections.
In response to his flight, the Tochigi police department officially placed Masuda on a wanted list on May 29. The Japanese Foreign Ministry issued a formal passport return order on Wednesday, June 3, 2026, to restrict his ability to travel further. The subsequent issuance of the Interpol Red Notice elevates the case to an international priority, allowing Japanese investigators to seek direct support from foreign law enforcement agencies to locate and detain the suspect.
Key Takeaways
- Suspect Identified: Kazuhiko Masuda, 48, is the primary target of an international search.
- Legal Action: Interpol has published a Red Notice, and the Japanese Foreign Ministry has revoked his passport.
- Criminal Network: Investigators believe the crime was coordinated via an anonymous messaging app, leading to the arrests of six other individuals.
- Current Status: Masuda is believed to be in Southeast Asia after transiting through China following the May 14 incident.
Moving Forward
As the investigation continues, the focus remains on tracking Masuda’s movements across Southeast Asia. Japanese authorities have indicated that once his specific location is confirmed, they plan to dispatch a specialized team to work alongside local authorities to facilitate his return to Japan. The case highlights the ongoing challenges Japanese law enforcement faces in combating crimes organized through digital platforms that exploit anonymous communication to recruit participants.
