Japan's northernmost major island - Hokkaido. Stretching out into the sea on the island's east coast is the Notsuke Peninsula. It is 26 kilometers long, but just 20 meters wide at its narrowest point. Made from sand carried on the ocean currents, its shape is gradually changing. Here lies a paradise for both birds and wild animals. When the wind is just right, fishermen can take countless riches from the sea. During the winter, the temperature remains below zero for months on end. Everything is frozen by the snow and icy winds. Over the years, people have continued to live here, despite the harsh conditions. This is the story of a peninsula surrounded by snow and ice.
