Mount Asahi: A volcano in the Daisetsuzan Volcanic Group and the highest mountain in Hokkaido. Its summit crater and fumaroles are the group’s best-known active volcanic features.
Daisetsuzan National Park: A national park in central Hokkaido encompassing the Daisetsuzan mountains. The volcanic group lies within this protected mountain landscape.
Mount Kuro: A volcanic peak in the Daisetsuzan range, known for its accessible summit area. It is one of the distinct peaks within the volcanic group.
Japan Meteorological Agency: Japan’s national agency for meteorological, seismic, and volcanic monitoring and warnings. Its volcano observatory tracks activity and issues alerts for Mount Asahi.
Ohachidaira: A broad volcanic crater in the central Daisetsuzan range. Its caldera-like form records explosive activity within the volcanic group.
Hokkaido: Japan’s northernmost main island and its largest prefecture. The Daisetsuzan volcanoes occupy Hokkaido’s central highlands.
Mount Hakuun: A peak in the Daisetsuzan range near Mount Asahi. Its proximity to Asahi places it among the group’s central volcanic landmarks.
Volcanic alert level: A graded public warning system indicating activity and access restrictions at Japanese volcanoes. Alert levels guide access to active areas of the Daisetsuzan group.
Fumarole: An opening that emits steam and volcanic gases from heated ground. Fumaroles around Mount Asahi reveal ongoing heat beneath the group.
Stratovolcano: A steep-sided volcano built from alternating layers of lava and fragmented volcanic material. Several peaks in the group are understood through this common volcano form.
