Mount Asahi (旭岳 Asahi-dake?) is the tallest mountain in Hokkaidō, Japan. Part of the Daisetsuzan Volcanic Group of the Ishikari Mountains, it is located in the northern part of the Daisetsuzan National Park.

The mountain is popular with hikers in the summer and can be easily reached from Asahidake Onsen via Asahidake Ropeway.

Sugatami Pond, directly below the peak, is famous for its reflection of the peaks, snow, and steam escaping from the volcanic vents.

History

Sulphur was once mined in the fumarolic areas.[2]

Geology

Mount Asahi is an active stratovolcano that arose 3 kilometres (1.9 mi) southwest of the Ohachi-Daira caldera.[2] The Japan Meteorological Agency gave the region rank C[4] in volcanic activity. In addition to the main peak, there is a smaller volcano emerging from the southeast shoulder of the mountain, Mount Ushiro Asahi or Rear Mount Asahi (後旭岳 Ushiro-Asahi-dake?). It is a stratovolcano 2,216 metres (7,270 ft) in height.[2] The volcano consists mainly of andesite and dacite.[4] That is Holocene volcanic non-alkali mafic rock less than 18,000 years old.[3]

Eruptive history

There is no historical record of the eruptions of Mount Asahi. Tephrochronology and radiocarbon dating have determined the following events:[2]

  • 3200 BC ± 75 years, Asahi Soria deposit, corrected radiocarbon dating, explosive eruption
  • 2800 BC ± 100 years, As-A tephra, corrected radiocarbon dating,explosive eruption and phreatic explosions
  • 1450 BC ± 50 years, As-B tephra, uncorrected radiocarbon dating, explosive eruption and phreatic explosions
  • 500 BC ± 50 years, Ash-b tephra, tephrochonology, explosive eruption and phreatic explosions and debris avalanches
  • 1739, tephrochronology, explosive eruption and phreatic explosions with possible eruption of the central vent and radial fissures

Mount Asahi currently exhibits steam activity in the form of fumaroles.[4]
