Yoronjima

, also known as Yoron, is one of the Amami Islands. The island, 20.8 km2 (8 sq. mi.) in area, has a population of approximately 6,000 people, and is administered as the town of Yoron, Kagoshima. Much of the island is within the borders of the Amami Guntō National Park. Yoronjima is the southernmost of the Amami Islands and is located approximately north of Hedo Point, the northernmost point of Okinawa Island, and south of the southern tip of Kyushu. The island is an elevated coralline island with a highest point above sea level. The coast of the island is surrounded by a coral reef. Yoronjima has a humid subtropical climate (Köppen climate classification Cfa) with very warm summers and mild winters. Precipitation is significant throughout the year, but is somewhat lower in winter. The island is subject to frequent typhoons. It is uncertain when Yoron Island was first settled. It was ruled by the Aji nobility from the 8th century onwards. From 1266 it was part of the Hokuzan Kingdom until its incorporation into the Ryukyu Kingdom in 1416. The samurai force from Satsuma Domain went around Yoron on their way to Okinawa during the 1609 Invasion of Ryukyu, after which its incorporation into the official holdings of that domain was recognized by the Tokugawa shogunate in 1624. Satsuma rule was harsh, with the inhabitants of the island reduced to serfdom and forced to raise sugar cane to meet high taxation, which often resulted in famine. After the Meiji Restoration the island was incorporated into Ōsumi Province and later became part of Kagoshima Prefecture. Following World War II, along with the other Amami Islands, it was occupied by the United States until 1953, at which time it reverted to the control of Japan. When Okinawa was governed by the United States, Yoronjima was the southernmost island Japanese mainlanders could go to for vacation, and it became a tourist spot. Tourism is still a large part of the local economy, with numerous resorts offering water sports and other activities.
