Distinguished from the surrounding area by its flatter land, Itaba no Dai Caldera contains waves and embankments called “lava waves” and “lava levees” that were formed by lava flowing out of Tsumakoi Pass Crater. Although neither seem particularly large, the lava waves reach about 2m and the lava levees about 5m. This area is the ideal spot to view the volcano as a whole. In addition, you can see many flowers, including erigeron thunbergii in spring, lilium auratum in summer, and swertia japonica in autumn.
