Surrounded by virgin forest trees such as beech and mizunara oak, Karikomi Pond is about 400 meters in circumference with a depth of 4.5 meters. Legend goes that a serpent living in Mt. Haku was confined (in Japanese, "karikometa") to the pond, which is where the name comes from. Although a stream flows into the pond, there is no area where the water can flow out of it; even so, that the water level of the pond always remains constant is a mystery. Bright-colored autumn leaves of maple, beech and rowan can be viewed from the end of October to the beginning of November, and the red leaves reflect on the shining surface of the pond, creating a spectacular sight.
