Intense energy is popping up from under the clefts of rocks all around you. Phreatic explosions are taking place right under your feet. Welcome to Owaku-dani Valley! It must have been so scary for the ancient people who lived near here in the Hakone mountain ranges. Even now I experience a kind of helpless feeling when I see this eerie view. Why? I think it’s because we can’t do anything in the face of the sudden destructive power of Mother Earth.
