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.

It is a royal farm house built about 280 years ago, and has been spared the war disaster of the Okinawa War to completely leave the private house structure of the Ryukyu Dynasty period. Since he was a local head of state around the year of Kyoho 10 (1720), he also has a stately status as a form of a shabby house. Other features include kitchens with low roofs to use the attic called tungwa for storage, and pig huts called fools. The influence of medieval Japanese houses and Chinese architecture can be seen everywhere, telling the life of a wealthy farmer in the Ryukyu period.

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.
