Jigokudani is the hot spring source for Noboribetsu Onsen, one of the top hot spring areas in Hokkaido. Experience first-hand why people call this canyon Jigoku (hell in Japanese) Valley. The mountain terrain, crowned with billowing steam and punctuated by the aroma of sulfur, is both unique and spectacular. The walkway features natural foot baths at the Oyunuma River where the hot springs from Lake Oyunuma meet up with the river and provide a place to heal your weary feet. In October, the white steam harmonizes beautifully with the autumn colors of the trees for a truly awe-inspiring sight.
