Futenmagu

In the central part of the main island of Okinawa, in Ginowan City, Futenmagu is counted among the eight shrines of the Ryukyu and is the only shrine in Ginowan City. Its greatest feature is the mystical limestone cave inner shrine, about 280 meters long, spreading deep behind the halls. Animal fossils from about 20,000 years ago have been excavated from this cave, and in 1991 it was designated a Place of Scenic Beauty. Since ancient times the cave has been revered as a sacred site, and walking through it wraps you in a holy air. Its deities are the Kumano gods and the gods of the Ryukyu ancient faith, and it is known for wide-ranging blessings such as matchmaking, protection from misfortune, safe childbirth, and the granting of wishes, a leading power spot of Okinawa.
