Iwaya Cave

"A stone cave located at the top of a mountain (commonly called ""Iwaya-san"") in the back of Shukunegi, Sado City. Geomorphologically, it is a sea-eroded cave, but it is sometimes called ""Iwaya Cave"" because oyster shells used to adhere to it. It is also known as a sacred site where Buddhist monks built Magaibutsu (Buddha statues in cliffs and rocks), 88 Buddhist statues, and a Kannon-do hall in the cave."
