Details for: Ontakesan
Massive On-take volcano is seen here from the NE with Kengamine, the summit peak, at the left-center. On-take is the second highest volcano in Japan and lies at the southern end of the Northern Japan Alps. The broad, elongated summit is cut by a series of small explosion craters along a NNE-trending line. On-take's first historical eruption in 1979 followed a lengthy period of quiescence. Ascent of the 3063-m-high On-take is one of the major objects of religious pilgrimage in central Japan.
