On August 20, 2026, four maintenance workers, aged between 50 and 60, were killed at Shin-Kanuma Station in Tochigi Prefecture when they were struck by a Tobu Railway Spacia X express train. The workers were performing vegetation control and herbicide application on the tracks at the time of the collision.

Initial reports indicated a potential breakdown in safety communication. Although a lookout had signaled to the driver that the tracks were clear, the workers remained on the line. While approximately 50 passengers were on the train, no injuries were reported among them, though service on the Tobu Nikko Line was suspended.

By August 22, Tochigi Prefectural Police had launched a special investigation into suspected professional negligence resulting in death. Authorities conducted searches of the offices of Tobu Construction (Tobu Kensetsu), a group company of Tobu Railway. Investigators are questioning site supervisors and the lookout, who reportedly signaled the train was ‘safe’ to proceed even while workers were still on the tracks.

New details suggest a breakdown in communication between lookouts, specifically that a relay lookout was unable to communicate with the primary lookout responsible for signaling the train. The train driver reported seeing a signal indicating workers had cleared the tracks and subsequently sounded the horn. The Ministry of Land, Infrastructure, Transport and Tourism has issued a warning to Tobu Railway as police analyze seized safety manuals and contracts to determine if safety management protocols were insufficient.
