The Tiao Yu Tai islands (called “Senkaku” in Japanese) are a group of eight uninhabited islands on the continental shelf, separated from the Liu Chiu islands by a deep underwater trench. These eight uninhabited islands and barren rocks have a land area of only 6.3 square kilometres. The islands are approximately 120 nm northeast of Taiwan, 200 nm east of the Chinese mainland, and 200 nm southeast of Okinawa. Most of the islets are clustered around the largest island, Uotsuri/Diaoyu, which covers roughly 8 hectares and lies 170 km northeast of Taiwan and 410 km west of Okinawa. Two outlying islets, Kobi-sho/Huangwei Yu and Akao-sho/Chiwei Yu, are located 31 km and 108 km from Uotsuri/Diaoyu Island, respectively. Diaoyu is at 25°45’N 123°29’E. The elevations of the highest points of islands: Diaoyutai 383 m, Beixiaodao 135 m, Nanxiaodao 149 m, Chongbeiyan 28 m.
