Fatal Express Train Collision at Shin-Kanuma Station

On August 20, a Tokyo-bound Spacia X limited-express train on the Tobu Nikko Line struck maintenance workers at Shin-Kanuma Station in Kanuma, Tochigi Prefecture. Four men in their 50s and 60s—three workers and a supervisor—were killed. Approximately 50 passengers aboard the six-car train were unharmed. The train was approaching the platform when it collided with the crew clearing vegetation.

Japan’s railway system is internationally recognized for its safety and punctuality, and fatal accidents involving passenger trains are rare. Maintenance work on active lines follows a “lookout” protocol: a designated staff member monitors approaching trains, signals workers with a flag, and the driver confirms the warning by sounding the horn before proceeding.

Tobu Railway Co. said the driver received a flag signal indicating the line was clear and sounded the horn before entering the station. The company has not confirmed whether the lookout’s warning reached the workers in time. The operator announced cooperation with the Tochigi prefectural police and fire department in the ongoing investigation.

Eyewitnesses on the train reported hearing a “strange noise” followed by an abrupt emergency brake application and a station announcement that staff were investigating the source of the noise. Passengers were held on the train for several minutes while the incident was assessed. Fire department officials told AFP that three of the victims were trapped under the train and one was on the platform when responders arrived.

Sources differ on the exact composition of the work crew. Some outlets describe a seven-person crew (four fatalities, three survivors), while others mention six workers present (four fatalities, two survivors). The role of the lookout personnel at the moment of impact remains unclear; investigators have not yet determined whether the flag signal was properly communicated to the workers. No definitive cause has been established, and the investigation is ongoing.
