Suspect in Custody

The Shizuoka Prefectural Police arrested a 38-year-old man at the scene. He is currently being charged with attempted murder. While police believe he acted alone, his motive remains unclear. Local residents expressed shock, noting that the area is typically quiet and safe.

Violent crime is historically rare in Japan, but this incident follows a string of high-profile attacks, including the 2022 assassination of Shinzo Abe. The nation continues to grapple with occasional stabbing rampages despite having some of the world's strictest weapon laws.
