Residents described the flames moving “in the blink of an eye.” Some had no time to pick up anything before leaving. The fire started on the evening of November 18, 2025, in the Saganoseki district of Ōita City, on the island of Kyushu, and it destroyed more than 170 buildings.
One person died. A woman in her 50s suffered mild burns. At least one person had been reported missing, and local authorities found a body presumed to be that person. Around 175 residents went to shelters, and up to 300 homes lost power.
Coverage describes it as Japan’s largest urban fire in nearly 50 years. Setting aside fires caused by earthquakes, the last one of this scale was in Sakata in 1976.
How it spread
Strong coastal winds drove the fire from narrow streets of old wooden houses up onto forested slopes. It even reached an uninhabited island more than 1 km offshore. About 48,900 square meters burned, roughly the size of seven football fields.
Residents said the tiny alleys and aging wooden buildings made it hard to get out and hard to fight the fire. More than 200 firefighters worked the blaze, and Self-Defense Force helicopters were sent in.
Response and recovery
Prime Minister Sanae Takaichi offered condolences and promised “maximum possible support.” Local and national governments are coordinating shelter, financial help and rebuilding aid. The neighborhood is a close-knit fishing community, and families there lost their homes.
The cause has not been determined. Investigators are looking at whether the fire was accidental or tied to weaknesses in how the neighborhood was built.
