Genbudo Cave (Genbu no Oiwaya)

This cliff with columnar joints on the left bank of the Kakkonda River was created by the cooling and hardening of magma flowing from the early eruptions of the Amihari volcanic group. The 70-meter-high cliff stretching 160 meters along the river is stunning! It was designated as a Special Natural Monument on February 19, 1953. Although some of the scenery was lost due to a collapse in 1999, the grand sight created by nature never ceases to amaze visitors who come to see it throughout the year. *The area 200 meters upstream and downstream of Genbudo Cave is dangerous and cannot be entered now.
