In the Karasawa cirque (36°17'N, 137°40'E) of the Hotaka massif, observations of the perennial snow patch, especially its size, were taken from 1968 to 1976. The size at the end of every ablation season ranged from 104 to 105 m2, and its average was 5.7 × 104 m2. Snow ablation from May 3 to October 10, 1976, is about 12.5 m in snow depth. The snow patch consists of two parts : the stratified layers due to snow falls, in which several ice layers are found, and disturbed layers due to debris of avalanche.
