Cave Ikura

A limestone cave 1,200 meters long and with a total elevation difference of 90 meters located in scenic Ikura Gorge in Ikura, Niimi City, Okayama Prefecture. The entrance to the cave is on a 240 meter tall limestone precipice. The cave was formed by rainwater erosion and features such as a 50 meter tall waterfall and icicle-like stalactites give the cavernous spaces within it a mystical quality. Visitors can view some 30 rare and unusually shaped stones and rock formations that are both strange and beautiful, such as the “Silver Screen,” “Water Clothing,” and “Jellyfish Stone.” Arisa no Miya, a shrine dedicated to a woman who suffered unrequited love and who is now revered as a goddess granting worshipers luck in love and marriage, stands at the cave’s exit.
