Troops and volunteers in Japan shoveled snow from roads and roofs on Sunday as the death toll from the country's heaviest snowfall on record rose to more than 60. Teams of troops tried to clear snow that had piled up to more than three meters in some of the worst-hit areas of Niigata prefecture and to re-open blocked roads in Nagano prefecture. Both areas are northwest of Tokyo. At least 63 people have died and over 1,000 injured since the unusually heavy snowfall began last month, Kyodo news agency said, citing a survey of local governments.
