Description

Mount Aka is a stratovolcano. This mountain is a center of the Yatsugatake-Chūshin Kōgen Quasi-National Park.

Stratovolcano Tall, conical volcano built up by many layers of hardened lava and other ejecta

A stratovolcano, also known as a composite volcano, is a conical volcano built up by many layers (strata) of hardened lava, tephra, pumice and ash. Unlike shield volcanoes, stratovolcanoes are characterized by a steep profile with a summit crater and periodic intervals of explosive eruptions and effusive eruptions, although some have collapsed summit craters called calderas. The lava flowing from stratovolcanoes typically cools and hardens before spreading far, due to high viscosity. The magma forming this lava is often felsic, having high-to-intermediate levels of silica, with lesser amounts of less-viscous mafic magma. Extensive felsic lava flows are uncommon, but have travelled as far as 15 km (9.3 mi).

Yatsugatake-Chūshin Kōgen Quasi-National Park

Yatsugatake-Chūshin Kōgen Quasi-National Park is a quasi-national park on Honshū in Japan. It is rated a protected landscape according to the IUCN. The park includes the Yatsugatake Mountains and the surrounding lava plateaus: Tateshina plateau, Kirigamine, and Utsukushigahara. It straddles the border between Nagano and Yamanashi prefectures. Mount Aka is the highest point in the park at 2,899 m. The volcanoes of the Yatsugatake mountains erupted from the middle of the Fossa Magna (ja) and spread skirts of lava south, east and west. Lake Matsubara, Shirakoma Pond, and Lake Shirakaba attract tourists to the region for boating, skating, and camping. Utsukushigahara is a lava plateau at the northern end of the park and offers views of the Northern Alps. The extensive lava plateau of Kirigahara is popular for hiking. There are also a number of onsens in addition to the hotsprings at Tateshina. The park was designated a quasi-national in 1964.

Climbing route

There are several routes to reach to the top of Mount Aka. The most popular route is from Minoto. It takes about four and half hours.
