Overview: Yambaru in the north of Okinawa Island was registered as a UNESCO Natural World Heritage site in July 2021. Its forests are home to numerous indigenous species such as the Okinawa rail, a flightless bird, and the Okinawa Ishikawa's frog, arguably the most beautiful frog in Japan. Since ancient times, the forest has supported people's lives and they've protected the forest in return. Now that the forest has natural heritage site status, tourist numbers are likely to rise. We'll find out how Yambaru's forest with its rare ecosystem and vast diversity can be preserved and passed down to future generations.
