“Amami Oshima, Tokunoshima, Northern Okinawa Island and Iriomote Island” were registered as World Natural Heritage Sites on July 26, 2021.
The Ryukyu Archipelago has a distinct geological background in which the islands were formed through repeated separation and merging with the Eurasia continent. The islands today are recognized as an extremely important site for biodiversity conservation, where internationally rare endemic species such as the “Yanbaru-kuina” (Okinawa rail) and “Iriomote-neko” (Iriomote wild cat) inhabit and breed within the unique biological evolution reflecting the islands’ geological history.
