The Senkaku Islands (尖閣諸島), also known as the Diaoyu Islands or Diaoyutai Islands (simplified Chinese: 钓鱼岛及其附属岛屿; traditional Chinese: 釣魚台群島), are a group of uninhabited islands controlled by Japan in the East China Sea. They are located roughly due east of mainland China, northeast of Taiwan, west of Okinawa Island, and north of the southwestern end of the Ryukyu Islands.
Since the transfer of administration from United States to Japan in 1971, ownership of the islands by Japan has been disputed by the People's Republic of China and the Republic of China (Taiwan). The Chinese claim the discovery and control of the islands from the 14th century. Japan controlled the islands from 1895 until her surrender at the end of World War II. The United States administered them as part of the United States Civil Administration of the Ryukyu Islands from 1945 until 1972, when the islands reverted to Japanese control under the Okinawa Reversion Treaty between the United States and Japan.
