Map of the Okinawa Plate and its neighbouring plates (in French
The Okinawa Plate is a long narrow tectonic plate stretching from the northern end of Taiwan to the southern tip of the island of Kyūshū. To the east lies the Ryukyu Trench and the Pacific Plate. It is separated from the Yangtze Plate (often considered part of the Eurasian Plate) by a rift that forms the Okinawa Trough which is a Back arc basin.
