World Natural Heritage
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.
Yanbaru, The Forest of Miracles
Iriomote Island, the last unexplored region in Japan
The ecosystem is home to many living organisms.
The Okinawa rail (iriomoteyamaneko) is found only in the Yanbaru region and the Iriomote wildcat is unique to Iriomote Island.
There are also examples of subspecies that are classified according to its region, such as the Okinawa tree lizard (inhabits Amami and various other Okinawan islands) and the Sakishima tree lizard (inhabits various Sakishima islands, excluding Yonaguni Island).
