The volcanic Mt. Furanodake rises in the south of the Taisetsu Mountain Range with a diverse environment. The program host sets out on a hike through a deep forest, crossing streams and enjoying beautiful waterfalls. After 2 hours of walking, he reaches an open space. It is a marshland formed by rainwater collecting on top of the lava. Later, we show you some footage of Northern Pika that stores leaves in its den to survive the long winter in an alpine zone, where not many plants are able to grow.

Our stage this time is Lake Furen which is connected to the Sea of Okhotsk in eastern Hokkaido Prefecture. It is a brackish lake with a circumference of 65km. The program host canoes down the river that flows into the lake, and enjoys watching white-tailed eagles and other birds. In the marshland facing the sea, he also observes sika deer at close range. Later, we show you some footage of red-crowned cranes raising their young by the lake where tide ebbs and flows, as well as red fox feeding on fish left on the tidal flats.

Shimukappu is located almost in the center of Hokkaido Prefecture. It is an area that gets severely cold in winter, where the snow-covered deep forest stretches. The program host explores the forest on a fat bike, which can be ridden easily through snowy terrain. He enjoys the spectacular scenery and the fluffy fresh snow as if he were a little child again. Later, we also show you the life of Siberian flying squirrels, which congregate in large groups only during winter by building a nest inside the hollow of a tree trunk.
