The patchy distribution of the vegetated patterned ground in the Pinus pumila shrub zone and the very limited distribution of the sorted patterned ground above the Pinus pumila limit are characteristics in Mt. Shirouma-dake, Northern Japan Alps and Taisetsu Volcanic Massif, central Hokkaido. This distribution pattern is largely different from those in the European and Himalayan mountains. In Japanese mountains, the lower periglacial zone in which vegetation-covered solifluction lobes mainly occur is completely lacking. The zone above the Pinus pumila limit in Japanese mountains correspond to the middle periglacial zone in the European and Himalayan mountains where both sorted and partly vegetation covered patterened ground occur.
