Overview: 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.
