The Liancourt Rocks, also known as Dokdo or Tokto ((:tokt͈o); , literally ''solitary island'') in Korean, and in Japanese, are a group of small islets in the Sea of Japan. While South Korea controls the islets, its sovereignty over them is contested by Japan. South Korea classifies the islets as Dokdo-ri, Ulleung-eup, Ulleung County, North Gyeongsang Province.〔 "Pursuant to Act 1395 amending Chapter 14-2, Ri-Administration under Ulleung County, Local Autonomy Law, Ulleung County, passed March 20, 2000, enacted April 7, 2000, the administrative designation of Dokdo addresses as 42 to 76, Dodong-ri, Ulleung-eup, Ulleung County, North Gyungsang Province, is changed to address 1 to 37, Dokdo-ri, Ulleung-eup, Ulleung County, North Gyungsang Province." "2000년 4월 7일 울릉군조례 제1395호로 독도리가 신설됨에 따라 독도의 행정구역이 종전의 경상북도 울릉군 울릉읍 도동리 산42～76번지에서 경상북도 울릉군 울릉읍 독도리 산1～37번지로 변경 됨."()〕 Japan classifies them as part of Okinoshima, Oki District, Shimane Prefecture. The Franco-English name of the islets derives from ''Le Liancourt'', the name of a French whaling ship which came close to being wrecked on the rocks in 1849. The Liancourt Rocks consist of two main islets and 35 smaller rocks; the total surface area of the islets is , with the highest elevation of found at an unnamed location on the West Islet. The Liancourt Rocks lie in rich fishing grounds which may contain large deposits of natural gas. == Geography == The Liancourt Rocks consist of two main islets and numerous surrounding rocks. The two main islets, called ''Seodo'' (; literally ''Western Island'') and ''Dongdo'' (; literally ''Eastern Island'') in Korean, and ''Ojima'' (男島; literally ''Male Island'') and ''Mejima'' (女島; literally ''Female Island'') in Japanese, are apart. The Western Island is the larger of the two, with a wider base and higher peak, while the Eastern Island offers more usable surface area. Altogether, there are about 90 islets and reefs, volcanic rocks formed in the Cenozoic era, more specifically 4.6 to 2.5 million years ago. A total of 37 of these islets are recognized as permanent land. The total area of the islets is about , with their highest point at on the West Islet. The western islet is about ; the eastern islet is about . The western islet consists of a single peak and features many caves along the coastline. The cliffs of the eastern islet are about high. There are two large caves giving access to the sea, as well as a crater. In 2006, a geologist reported that the islets formed 4.5 million years ago and are quickly eroding. 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「Liancourt Rocks」の詳細全文を読む スポンサード リンク
