Onigajo in Kumano is a magnificent natural wonder sculpted over tens of millions of years. Crustal uplift, prolonged weathering, and coastal erosion created massive rock walls stretching about 1.2 km, with layers of raised rock shelves, sharp and rugged formations, and sea caves of all sizes. They look as though they were carved by demons wielding giant axes, making for a visually stunning sight.
It is also one of the component sites of the Sacred Sites and Pilgrimage Routes in the Kii Mountain Range World Heritage Site and is designated as a National Place of Scenic Beauty and Natural Monument. Walking along the coastal trail, the deep blue Kumano Sea contrasts sharply with the dark gray rock walls. Waves crash against the shore with heart-pounding force, the sea breeze carries a salty scent, and beneath my feet are rocks worn down over the years. I carefully made my way along, gripping the rock wall as if walking on thin ice.
From the Oni-no-Miharashidai lookout, you can gaze out over the expansive rock terrace known as Senjojiki and other sights. With the sea and sky blending into one, you can feel the immense power of nature even more, inspiring a sense of awe. The legend of Sakanoue no Tamuramaro defeating pirates adds another layer of mystery and a rugged sense of history to this unusual rocky coastline. Exploring the entire area takes about 90 minutes round trip, so come and fully enjoy the extraordinary beauty created by nature.
