The men were among five foreigners engulfed in Sunday's avalanche, which took place at about 2:30 p.m. (0530 GMT) on the eastern slope of Mount Hakuba Norikura in the ski resort, a police spokesman said.

"The rescuers are now trying to come down to the mountain base with the bodies," the spokesman added, saying police would need time to pinpoint details of the victims, such as their nationalities.

Media said one was Austrian and the other American, however.

The other three skiers had climbed down the mountain on their own on Sunday, the spokesman said. The five were skiing in two separate groups on the mountain, which is 2,469-m (8,100-ft) high.

Weather authorities had issued an avalanche warning for the area, following heavy snowfall in the past few days.
