TOKYO: A massive crash in snowy weather has killed one person and injured 26 on an expressway in Japan as the country kicked off its end-of-the-year holiday season.

The Gunma prefectural highway police said Saturday that the pileup on the Kan-etsu Expressway late on Friday started with a collision between two trucks in the town of Minakami, about 160 km northwest of Tokyo.

A 77-year-old woman from Tokyo died, police said. Out of the 26 injured, five were reported to be in serious condition.

The crash of the trucks blocked parts of the expressway, and cars coming from behind them were unable to brake on the snowy surface. More than 50 vehicles were involved in the pileup, police said.

A fire erupted at the far end of the pileup, spreading to more than a dozen vehicles, some of which were completely burned. Nobody was injured from the fire, which was extinguished about seven hours later, police said.

A warning about heavy snow was in effect late Friday, when many Japanese started their year-end and New Year holidays.

Parts of the expressway remained closed for police investigation, removal and cleaning of the wreckage.
