Hokkaido Official Tourism Site HOKKAIDO LOVE!

Admire the breathtaking mirror-like reflection of Mt. Asahidake on the glass-like water, and the enchanting rainbow fountain that dances in the light.

Located upstream of the Chubetsu River in the Ishikari River system, this serene lake was formed by a multipurpose dam completed in 2007. Nestled at the foot of Mt. Asahidake, Hokkaido’s highest peak, the lake is cradled by deep forests and dramatic columnar jointed cliffs. These natural barriers shield the area from the wind. As a result, the lake often becomes a massive, perfect mirror. On calm days, the reflection of the snow-capped mountains against the crystal-clear surface offers a moment of profound stillness, broken only by the distant song of wild birds.

At Fukuro Pond on the eastern side, you will find a remarkable sight: a fountain reaching 14.8 meters high, powered entirely by natural water pressure from the Daisetsu Asahidake source. When the sunlight hits the mist at just the right angle, a vibrant spectacle known as the "Seven-Colored Fountain" appears, painting rainbows against the greenery. For those seeking adventure, the lakeside park offers a sandy shore where you can launch a canoe or SUP. Feeling the cool, pure water as you paddle through the panoramic scenery provides a refreshing connection to nature. In autumn, the surrounding forest transforms into a brilliant tapestry of red and gold, creating a fleeting harmony that lingers softly on the lake’s surface.
