Among the islands of Yonaguni, which are surrounded by sheer cliffs, the east-south is the area with the most severe and masculine landscapes. It is dotted with strange rocks that have been created over time due to the rough open sea. Close to Higashizaki, there is the Sannine stand, which shows the fault, which is divided into several layers, as a rock face. From the observation deck, the warship rock, which looks like a warship as its name suggests, is still washed by the waves. About a five-minute walk from Saint-Ninudai, there is a standing rock with a legend that a young man who could no longer descend from the top of the rock was helped by God.
