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.

In spring 2021, Shinji High School in Shimane Prefecture, western Japan, set up the first class in the prefecture solely for students with foreign roots. As well as regular subjects, they get special support in an extra one titled "Understanding Japanese." The area's foreign population has surged in recent years. While elementary and junior high schools offer language support, there is hardly any at high schools, so several students have had to give up on studying or pursuing their ambitions. We follow four Japanese Brazilian students at the school as they take a step toward their dreams.
