Yonaguni, Okinawa Prefecture, Kyūshū Region, Japan

🇯🇵 Yonaguni, one of the Yaeyama Islands, is the westernmost inhabited island of Japan, lying 108 km from the east coast of Taiwan, between the East China Sea and the Pacific Ocean proper. The island is administered as the town of Yonaguni, Yaeyama Gun, Okinawa, and there are three settlements: Sonai, Kubura, and Higawa. It is known for billfish fishing and as a diving spot. In 1987, divers discovered the Yonaguni Monument, a rock formation that some believe may be man-made.

It is also home to two Ryūkyūan writing systems, pictographic "kaida-di" (also used on Ishigaki and Taketomi islands where it is called "kaida-ji") and the symbols used to indicate family names, "dāhan" (also used on Ishigaki Island where they are called "yāban").

History Presently, the oldest confirmed ruins are the ruins in Tuguru Beach. 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 centre 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: Yonaguni was 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 (Yonagunian language: Irinzati) on the western edge of the island, there is a monument inscribed with the words: "The westernmost point in Japan". • The western third of the island is not part of Japan's air defense identification zone or flight information region; instead, it sits in Taiwan's air defense identification zone and flight information region. (Please refer to the article on Yonaguni Airport for more details.) • 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 108 km (67 mi) and therefore closer than Ishigaki, which is 118 km (73 mi) away. For further comparison, Yonaguni is much closer to Taipei (the capital of Taiwan) at approximately 160 km (99 mi) than its own capital (Tokyo), which is about 2,000 km (1,243 mi) 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. Rivers • Tahara River (Okinawa).
