The summit of Ontake is shown here with the Northern Japan Alps on the horizon. Norikura, another Holocene volcano, forms the broad massif in the mid-distance. Ontake is constructed within a largely buried 4 x 5 km caldera. Ichinoike in the foreground is one of a series of small craters at the broad summit.
