To-no-hetsuri is the largest scenic spot in Okawa Hatori Prefectural Park. It was designated as a national natural monument in 1943.

"Hetsuri” means a cliff or steep slope along a river in the local dialect, and the name ‘Tou no Hetsuri’ comes from the meaning of a steep cliff in the shape of a pagoda.

Walking through the deeply gouged rock arcade, you will see strange and monstrous rocks towering like a huge stone tower.

It is a magnificent landscape created by the million-year process of erosion and weathering of the Ookawa River (Aga River).

In early summer, mountain hydrangeas hang down from the strange rocks, and in autumn, the leaves turn beautiful colors.
