Presently, the oldest confirmed ruins are the Tuguru Beach ruins. Due to the southern style stone tools found, it is thought that a culture influenced by Southeast Asia existed here at one time. After this point, the history of the island of Yonaguni is unclear, but in the Gusuku Era, settlements were formed on the top of the plateau. The Shima Nakamura Ruins are one example, and it is known for being the birth village of the famous woman chief, San’ai Isoba. From the time of the Ryūkyū Kingdom, Yonaguni prospered as a commerce center with Taiwan. Due to World War II, until it was placed under control of the United States Civil Administration of the Ryukyu Islands, the number of people involved in smuggling surged in the area. The population in 1947 had reached 12,000, but although Yonaguni became incorporated as a town, a crackdown on smuggling led to a sharp decrease in the population. Ishigaki and the surrounding towns and cities are discussing a merger, with the exception of Yonaguni which abstained, cutting the members of parliament from 12 in half, down to 6.
1522 Invaded by the Ryūkyū army and became a territory of the Ryūkyū Kingdom.
1872 The Ryūkyū Kingdom is abolished; in its place, the Ryūkyū Domain is established and the island becomes a territory of the Ryūkyū Domain.
1879 The Ryūkyū Domain is abolished and becomes Okinawa-ken.
1908 The island municipal system abolishes the magiri system, and the Ishigaki-magiri, Ōhama-magiri, and Miyara-magiri join the island of Yonaguni to become Yaeyama-son.
1914 Through a division of Yaeyama-son, the village of Yonaguni-son is formed.
1948 Yonaguni-chō is incorporated as a town.
Geography
Yonaguni is the westernmost part of Japan and is a midpoint between the island of Ishigaki and Taiwan. At Cape Irizaki on the western edge of the island, there is a monument inscribed with the words: “The westernmost point in Japan.”
The distance between the shoreline of Cape Irizaki on Yonaguni and that of Wushihbi Coastal Nature Reserve in Su'ao Township, Yilan County, Taiwan is and therefore closer than Ishigaki, which is away. For further comparison, Yonaguni is much closer to Taipei at approximately than its own capital, which is about away. Due to this it is attempting to establish closer relations with Taiwan, including attempting to set up easier access to and from cities in Taiwan, with irregular service to Hualien already established. Further cooperation has been opposed by the central government, thus the lack of further progress.
Kubura Junior High School – Japan’s westernmost school
Because there are no high schools on the island, students entering high school must attend on the Okinawa mainland or on the island of Ishigaki, and 100% of junior-high schoolers continue on to high school.
