Story : In this episode, our stage is a popular tourist destination that is also registered as a "UNESCO Global Geopark", Lake Toya. The caldera lake that was created 110,000 years ago creates a myriad of breathtaking views. In the lake and surrounding rivers, the spawning of Masu salmon can also be seen, and they, along with many other fish, develop healthily thanks to the nutrients provided by the volcanic ash. In this program, we will witness the rare footage of wild animals that capture their ecology, and our host Charlotte Kate Fox will also go on a hike around the surrounding area.
