The Senkaku Islands, known as the Diaoyu Islands in China and the Diaoyutai Islands in Taiwan, are a group of uninhabited islands in the East China Sea, administered by Japan. They were historically known in the Western world as the Pinnacle Islands. The islands are located northeast of Taiwan, east of China, west of Okinawa Island, and north of the southwestern end of the Ryukyu Islands.
The islands are the focus of a territorial dispute between Japan, China, and Taiwan. China claims the discovery and ownership of the islands from the 14th century, while Japan maintained ownership of the islands from 1895 until its surrender at the end of World War II.
