On the morning of 11 November 2026, a fire broke out at a factory in Kunugizawa Nishi, Yamagata City, Japan, which the source identifies as a factory of Shachihata Engineering. According to the fire service, passers-by reported black smoke rising from the roof at about 10:00 and called the emergency number 119. The fire was extinguished about three and a half hours after the call. Rooftop solar panels and other items on the roof were burned. All employees evacuated and no one was injured. The source does not report the cause of the fire, the size of the solar array or the extent of the damage to the building.
Contributing factors
Not reported. The source does not give a cause for the fire or describe how it spread to the roof.
Lessons learned
- Rooftop solar arrays should be included in the fire risk assessment and pre-incident plan for any building, so that responders know where the panels and DC cabling are.
- Operators should keep current layout drawings and clearly marked DC isolation points for rooftop arrays and make them available to the fire service.
- Evacuation and roll-call procedures should be tested so that all staff are accounted for quickly when smoke is seen from the roof.
