History [edit]
In the 12th century, it was incorporated to the Ryūkyū Kingdom.[citation needed] In the 17th century, it was incorporated into the Japanese han of Satsuma. By 1879, the island was formally incorporated into Japan.
Until the early 20th century, Yonaguni was part of the larger Yaeyama village, which included the neighboring Yaeyama Islands. In 1948, it became an independent village. From 1945 to 1972, it was occupied by the United States and was then returned to Japan to form a part of Okinawa Prefecture.
On May 4, 1998, a part of the island was destroyed by a submarine earthquake.
As a result of increased tensions between Japan and China/Taiwan over the disputed sovereignty of the Japanese-controlled uninhabited Senkaku/Diaoyu/Tiaoyutai Islands which are located roughly 80 nautical miles north-northeast of the Yonaguni Islands, Japan intends to station 100 troops on Yonaguni to counter a perceived threat from Chinese forces.[2][dated info]
Notable features [edit]
Yonaguni is known in Japan for the hanazake, a 120-proof rice-based distilled beverage (awamori) produced only on the island.
The island is also the only natural habitat of a distinctive horse breed, the Yonaguni horse.
Yonaguni is a popular attraction for divers because of the large numbers of hammerhead sharks that gather in the surrounding waters during winter.
Yonaguni Monument [edit]
In the 1980s, local divers discovered a striking underwater rock formation off the southernmost point of the island. This so-called Yonaguni Monument has staircase-like terraces with flat sides and sharp corners. Although the majority of the academic society regard the rock formation as natural joint, Masaaki Kimura, a professor of seismology in University of the Ryukyus and some media believe it is an artificial (or artificially modified) structure engraved or built 2,000 to 3,000 years ago.[3]
Patrick D. Nunn, Professor of Oceanic Geoscience at the University of the South Pacific, has studied these structures extensively and notes that the structures below the water continue above and are slate that "has been fashioned solely by natural processes" and that "there seems no reason to suppose that they are artificial."[4]
Transportation [edit]
