TOKYO: Heavy snow battering northern Japan in the last two weeks has been blamed in 35 deaths nationwide so far, including people suffering sudden heart attacks or slipping while shoveling snow, government officials said Wednesday.

As of Wednesday, 15 prefectures have been affected, with the amount of snow piled up in the worst hit areas estimated to have reached 2 meters (6.5 feet).

The biggest number of snow-related fatalities, at 12 people, was reported in Niigata Prefecture, a rice-growing region in northern Japan, including a man in his 50s who was found collapsed on the roof of his home in Uonuma city on Jan. 21.

In Nagaoka city, a man in his 70s was spotted collapsed in front of his home and rushed to the hospital where he was pronounced dead. He is believed to have fallen from the roof while raking snow, according to the Niigata government.

Japan’s chief government spokesperson warned that, although the weather was getting warmer, more danger could lie ahead because snow would start melting, resulting in landslides and slippery surfaces.
