Yonaguni Island

Yonaguni is the westernmost inhabited island of Japan, located in the Yaeyama Islands, and is administered as the town of Yonaguni, Yaeyama Gun, Okinawa. The island has a long and unclear history, with early human migration from Taiwan being a subject of scholarly debate, and the first written record of the island dating back to a 1477 Korean document. Yonaguni was incorporated into the Ryūkyū Kingdom in the 15th century and was formally annexed by Japan in 1879, and it has been occupied by the United States and returned to Japan several times. Today, the island is home to a coastal monitoring/early warning station with radar and other sensors, and there have been discussions to develop tourism in Yonaguni via a regular, direct ferry service from Taiwan.learn more on wikipedia
