Location map of the Ryukyu islands (Nansei islands). The island groups are labeled from northeast to southwest: Ōsumi, Tokara, Amami, Okinawa, Daitō (positioned to the east, isolated in open ocean), Miyako, Senkaku, and Yaeyama. Japan's southwestern coastline appears in the upper right corner, and Taiwan's distinctive elongated form occupies the lower left, with its central mountain spine rendered in yellow-brown relief. The Chinese coastline is partially visible along the far left edge. https://en.wikipedia.org/wiki/Ryukyu_Islands#/media/File:Location_of_the_Ryukyu_Islands.JPG
