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.

A waterfall with a height of about 20m appears when you drive about 5 minutes into the mountains from the National Highway No. 58 Ikuta intersection.

In front of the west port is the site of a phosphorous ore mining business that operated until 1950. The brick building was the place where the ore was dried, the building on the left was the storage building. Phosphorite, which was purified and dried here, was carried by a trolley to the western port and was carried out to the outside of Hokidaitō. Phosphorite mining operations reached their height before the war, and the island's population was over 2000, it said. It has been designated as a National Historic Site.
