Overview
- Police are still seeking Kenji Oyama, 42, wanted in the killings of homeowners Sumie Tanaka, 74, and her daughter Chihiro, 52, in a Tatsuno City residence.
- Investigators say Oyama was stopped by officers on May 16 and reportedly told them, "I killed someone," a disclosure that has focused renewed scrutiny on why the encounter did not stop the later murders.
- Neighbors reported seeing a man matching Oyama’s description near the scene in the early hours of May 17, and police believe he may have stayed in the area before disappearing.
- Separately, Tokyo police on May 26 arrested 25‑year‑old Yusho Yamao, a member of a Sumiyoshi‑kai affiliated group, on suspicion of abducting people in Shinjuku to be sent overseas to work at fraud hubs.
- Other concurrent developments include an Economy Ministry delegation arriving in Moscow for talks, the Akagi family’s announcement of planned summer litigation over withheld Moritomo documents, a confirmed death of retail figure Toshifumi Suzuki, a Hokkaido bear sighting, and a two‑building fire in Fukuoka.
