Lake Kussharo
Lake Kussharo is Japan's largest caldera lake, stretching approximately 20 kilometers north to south, and the largest freshwater lake that freezes over on its entire surface. Mt. Mokoto, which created Lake Kussharo, is known for its volcanic eruptions that covered the entire Hokkaido region with its ash in ancient times.
If you dig into the sandy beach along Lake Kussharo, you'll find warm hot spring water bubbling up! It's such a unique experience, so definitely check out the 'Sunayu' area if you visit!
