Thousands evacuate in Japan as forest fires close in on homes

Fires have scorched more than 730 hectares since breaking out on Wednesday
Two forest fires in Iwate Prefecture were burning for a fourth consecutive day on Saturday, marking one of the worst mountain wildfire disasters in decades, according to the ministry of agriculture, forestry and fisheries.

The fires have scorched more than 730 hectares (1,800 acres) since breaking out on Wednesday afternoon in two districts of Otsuchi.

The first blaze engulfed a mountainous area, followed by another about two hours later, roughly 10km (6.2 miles) away, near residential neighbourhoods.

Pictures showed a large column of smoke rising up in the sky near the town of Otsuchi as helicopters dropped water on the burning forest.

The fire could be smelled up to 30km away, residents have said.

"Ultimately, I do hope it'll rain," a resident in Otsuchi told public broadcaster NHK.

Eight buildings, including one residence, have been engulfed in fire, officials said, but no casualties have been reported.

Experts say seasonal dry weather, combined with layers of dried fallen leaves on forest floors, is a recurring trigger for wildfires in parts of Japan each year.

Taken together, the current blazes have burned the third-largest area on record in the country, according to media reports – behind a 2025 wildfire in Ofunato that consumed about 3,370 hectares, and the Kushiro fire of 1992, which burned around 1,030 hectares.

The Ofunato blaze early last year was the worst Japan had seen in more than half a century.

Scientists have long warned that climate change , driven by the burning of fossil fuels, will intensify and prolong periods of drought, creating conditions increasingly conducive to wildfires.
