Our stage this time is Mt. Tomuraushi in the very center of Hokkaido Prefecture. It's considered impassable during the harsh winter months, while the forest at its foot is good for trekking. Our program host, Charlotte Kate Fox, dons snow shoes and treks the forest covered with a blanket of snow. On her way to the waterfall that never freezes even during winter, she also observes snow crystals and bear claw scratches on a tree. In addition, we show you rare footage of Siberian flying squirrel and other animals dwelling in the forest.
