is a mountain located near the town of Higashikawa, Hokkaido and the tallest mountain on the Japanese island of Hokkaido. It is part of the Daisetsuzan Volcanic Group of the Ishikari Mountains, located in the northern part of the Daisetsuzan National Park.
Its native Ainu name is Kamui-mintara, which means "the playground of the gods".
The mountain is popular with hikers in the summer and can be easily reached from Asahidake Onsen via Asahidake Ropeway. During winter, the mountain is open for use by skiers and snowboarders.
Sugatami Pond, directly below the peak, is famous for its reflection of the peaks, snow, and steam escaping from the volcanic vents.
Sulphur was once mined in the fumarolic areas.[2]
Mount Asahi is an active stratovolcano, 2291m (7,516feet) in height that arose 3km (02miles) southwest of the Ohachi-Daira caldera. The Japan Meteorological Agency gave the region rank C in volcanic activity. The volcano consists mainly of andesite and dacite, Holocene volcanic non-alkali mafic rock less than 18,000 years old.[3] In addition to the main peak, there is a smaller volcano emerging from the southeast shoulder of the mountain, .
Whilst there is no historical record of the eruptions of Mount Asahi, tephrochronology and radiocarbon dating have determined the following events:
Mount Asahi currently exhibits steam activity in the form of fumaroles.[4]
