Shikaribetsu Group
"Shikaribetsu volcano consists of a group of andesitic-to-dacitic lava domes west and south of Lake Shikaribetsu in central Hokkaido. The youngest domes, which were mapped as Holocene (Japan Association of Quaternary Research, 1987), were constructed along a ENE-WSW line south of the lake. The age of the latest eruptions is not known precisely, but is less than 20,000 years (Nakano et al., 2001-). The largest dome, Higashi-Nupukaushinupuri, was built at the SW, breached end of a horseshoe-shaped crater. Two or more large debris-avalanche deposits extend to the south."  -Smithsonian Volcano Archive
