Early historical context

Records of these islands date back to as early as the 15th century. They were referred as Diaoyu in books such as Voyage with a Tail Wind (1403) and Record of the Imperial Envoy's Visit to Ryūkyū (1534). Adopted by the Chinese Imperial Map of the Ming Dynasty, both the Chinese name for the island group (Diaoyu) and the Japanese name for the main island (Uotsuri) both literally mean "angling

Angling is a method of fishing by means of an "angle" . The hook is usually attached to a fishing line and the line is often attached to a fishing rod.

The first reference to the islands in a book published in English was Edward Belcher

's 1848 account of the voyages of HMS Sammarang. Captain Belcher observed that "the names assigned in this region have been too hastily admitted." Belcher reported anchoring off Pinnacle Island in March 1845.

In 1870s and 1880s, the English name Pinnacle Islands was used by the British navy for the rocks adjacent to the largest island Uotsuri Jima/Diaoyu Dao (then called Hoa-pin-su); Kuba Jima/Huangwei Yu (then called Ti-a-usu); and Taishō Jima/Chiwei Yu. The name "Pinnacle Islands" is used by some as an English-language equivalent to "Senkaku" or "Diaoyu".

In 1900, when Tsune Kuroiwa, a teacher at the Okinawa Prefecture Normal School, visited the islands, he adopted the name Senkaku Retto , literally Pinnacle Islands, to refer the whole island group, based on the British name. The first official document recording the name Senkaku Retto was by the Japanese Ministry of Foreign Affairs in Nihon Gaiko Monjo (日本外交文書, Documents on Japanese Foreign Relations) in the 1950s. In Japanese, and were translations used for these "Pinnacle Islands" by various Japanese sources. Subsequently, the entire island group came to be called Senkaku Rettō, which later evolved into Senkaku Shotō.

The collective use of the name "Senkaku" to denote the entire group began with the advent of the controversy in the 1970s.

History under Japanese and US control

 processing plant on the islands with 200 workers. The business failed in 1940 and the islands have remained deserted ever since. The plots of land on the islands still technically belong as private property to Koga's descendants.

The islands were under US government occupation authority from 1945 until 1972. Since the islands reverted to Japanese government control in 1972, the mayor of Ishigaki has been given civic authority over the territory. The Japanese central government, however, has prohibited Ishigaki from surveying or developing the islands. On December 17, 2010, Ishigaki declared January 14 as "Pioneering Day". China condemned Ishigaki's actions.

Geography

The island group consists of five uninhabited islets and three barren rocks.

These minor features in the East China Sea are located approximately 120 nautical miles northeast of Taiwan, 200 nautical miles east of the Chinese mainland and 200 nautical miles southwest of the Japanese island of Okinawa.

 (which Japan accepted as part of the San Francisco Peace Treaty) required that Japan relinquish control of all islands except for "the islands of Honshū, Hokkaidō, Kyūshū, Shikoku and such minor islands as we determine", and they state that this means control of the islands should pass to China.

Japan does not accept that there is any ownership dispute, asserting that the islands are an integral part of Japan. Japan has rejected claims that the islands were under China's control prior to 1895, and that these islands were contemplated by the Potsdam Declaration or affected by the San Francisco Peace Treaty.

The controversy has at least two dimensions: (a) territorial sovereignty, which is a legacy of history; and (b) relevant jurisdictional rights and interests in maritime boundaries

China strongly protested, and demanded an immediate release of the Chinese fishermen. The crew was released on September 13, 2010, while the captain was held until September 24, and none were charged. The incident disrupted official and non-official exchanges and activities between the two countries.
