"The massive On-take stratovolcano, the second highest volcano in Japan, lies at the southern end of the Northern Japan Alps. On-take is constructed within a largely buried 4 x 5 km caldera and occupies the southern end of the Norikura volcanic zone, which extends northward through Norikura volcano to Yake-dake volcano. The older volcanic complex consisted of at least four major stratovolcanoes constructed from about 680,000 to about 420,000 years ago, after which On-take was inactive for more than 300,000 years. The broad, elongated summit of the younger edifice is cut by a series of small explosion craters along a NNE-trending line. Several phreatic eruptions from On-take post-date the roughly 7300-year-old Akahoya tephra from Kikai caldera. On-take's first historical eruption took place in 1979. A non-eruptive landslide in 1984 produced a debris avalanche and lahar that swept down valleys south and east of the volcano. Ascent of the 3063-m-high On-take is one of the major objects of religious pilgrimage in central Japan."  -Smithsonian Volcano Archive
