Rocks that rear up offshore of an island or at the mouth of a bay are generally called Tachigami (standing god) Rock. People regard them as sacred objects of worship. Yonaguni Island’s Tachigami Rock stands up vertically in the sea south of the San-ninu Heights scenic spot in the southeastern part of the island. There is a legend that once upon a time, some young people hunting seabird eggs climbed up Tachigami Rock and then couldn’t get down. They prayed to the gods and were delivered safely back to San-ninu. The Tachigami Rock observation platform is a five-minute walk from the San-ninu Heights.
