is the smallest ( long and between wide) and least populous (4,141,955 as of 2005) of the four main islands of Japan, located south of Honshu and east of the island of Kyushu. Its ancient names include ''Iyo-no-futana-shima'' (), ''Iyo-shima'' (), and ''Futana-shima'' (). The current name refers to the four former provinces that made up the island: Awa, Tosa, Sanuki, and Iyo. ==Geography== Shikoku island, comprising Shikoku and its surrounding islets, covers about and consists of four prefectures: Ehime, Kagawa, Kōchi, and Tokushima. Across the Inland Sea lie Wakayama, Osaka, Hyōgo, Okayama, Hiroshima, and Yamaguchi Prefectures on Honshu. To the west lie Ōita and Miyazaki Prefectures on Kyushu. The 50th largest island by area in the world, Shikoku is smaller than Sardinia and Bananal, but larger than Halmahera and Seram. By population, it ranks 23rd, having fewer inhabitants than Sicily or Singapore, but more than Puerto Rico or Negros. Mountains running east and west divide Shikoku into a narrow northern subregion, fronting on the Inland Sea, and a southern part facing the Pacific Ocean. Most of the 4.5 million inhabitants live in the north, and all but one of the island's few larger cites are located there. Mount Ishizuchi () in Ehime at is the highest mountain on the island. Industry is moderately well developed and includes the processing of ores from the important Besshi copper mine. Land is used intensively. Wide alluvial areas, especially in the eastern part of the zone, are planted with rice and subsequently are double cropped with winter wheat and barley. Fruit is grown throughout the northern area in great variety, including citrus fruits, persimmons, peaches, and grapes. Because of wheat production Sanuki udon () became an important part of the diet in Kagawa Prefecture (former Sanuki Province) in the Edo period. The larger southern area of Shikoku is mountainous and sparsely populated. The only significant lowland is a small alluvial plain at Kōchi, the prefectural capital. The area's mild winters stimulated some truck farming, specializing in growing out-of-season vegetables under plastic covering. Two crops of rice can be cultivated annually in the southern area. The pulp and paper industry took advantage of the abundant forests and hydroelectric power. The major river in Shikoku is the Yoshino River. It runs from its source close to Mount Ishizuchi, flowing basically west to east across the northern boundaries of Kōchi and Tokushima Prefectures, reaching the sea at the city of Tokushima. The Yoshino is famous for Japan's best white-water rafting, with trips going along the Oboke Koboke sections of the river. Shikoku has four important capes. Gamōda in Anan, Tokushima is the easternmost point on the island, and Sada in Ikata, Ehime the westernmost. Muroto in Muroto, Kochi and Ashizuri, the southern extreme of Shikoku, in Tosashimizu, Kochi, jut into the Pacific Ocean. The island's northernmost point is in Takamatsu, Kagawa. Unlike the other three major islands of Japan, Shikoku has no volcanoes. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Shikoku」の詳細全文を読む スポンサード リンク
