Lake Kussharo
Circumference 57km, Nakajima Island floating in Japan's largest caldera lake
Lake Kussharo, with a circumference of 57km, is Japan's largest caldera lake and the largest lake within Akan-Mashu National Park. The name derives from the Ainu word "Kutcharo," meaning "a place where the lake becomes a river and flows out."
Standing on the lakeshore, you see Nakajima Island floating quietly beyond the blue water surface. From the south shore, Wakoto Peninsula juts out into the lake, its unique topography creating beautiful scenery. Around this lake formed by volcanic activity, hot springs bubble up everywhere, and rustic open-air baths dot the lakeshore. Immersing your hand in the lake water brings a pleasantly cool sensation, with only the sound of waves quietly echoing.
At this lake, the second largest in Hokkaido after Lake Saroma, you can enjoy activities such as canoeing and windsurfing. In winter, the omiwatari phenomenon sometimes appears on the lake surface, showing different expressions throughout the four seasons. You can spend time enveloped in magnificent nature, where the sulfurous scent of hot springs drifts and wild birds sing.
