Okunoyu is a small, mystical pond located near Lake Oyunuma in Noboribetsu, a short distance from Jigokudani (Hell Valley). This sulfuric hot spring features an emerald green color and bubbling waters, creating a visually stunning and somewhat otherworldly scene. The pond's surface temperature ranges from 75 to 85 degrees Celsius, so viewing is from a safe distance. It's easily accessible by car with parking available near Lake Oyunuma, or via a walking path from Jigokudani. The autumn foliage season offers particularly beautiful views. Be sure not to miss this unique natural attraction when visiting Noboribetsu.
