Lake Kussharo (屈斜路湖)
Lake Kussharo is located in the Akan National Park in Eastern Hokkaido. It is the largest caldera lake in Japan and also the largest freshwater lake in Japan to freeze over completely in winter. On the south side the Wako Peninsula juts out and in the lake is Nakajima Island. It is said that about 500 swans migrate to the lake during the winter months and it is a popular spot to take photos.

Hokkaido Areas

Not just a prefecture but an island of its own, Hokkaido is the most northerly prefecture and island of the Japanese archipelago. Arriving in Hokkaido, which is rural and bursting with breathtaking nature, means entering a world where vast national parks, towering mountains, and natural hot springs can be found at every turn. Come December, these natural splendors freeze over and morph into a winter wonderland.
