The Daisetsuzan Volcanic Group (大雪山系, Daisetsu-sankei, also called Taisetsu-zan) is a volcanic group of peaks arranged around the 2 kilometres (1.2 mi) wide Ohachi-Daira (御鉢平, Ohachi-daira) caldera in Hokkaidō, Japan. In the Ainu language it is known as Nutapukaushipe (which means "the mountain above the river"),[2] Nutaku Kamushupe, or Optateske.[3] These peaks are the highest in Hokkaidō. The group lends its name to the Daisetsuzan National Park in which the volcanic group is located.
