It is a pond deep in the mountains where groundwater from Lake Mashu springs up. It is called 'Kaminoko' (Child of God) Pond due to a legend that it is formed from the underflow water of Lake Mashu (Kamuy-to = Lake of the Gods).

What makes Lake Mashu significantly different from other lakes is that it has no rivers flowing into or out of it. Despite this, its water level does not change even in spring when a large amount of snowmelt flows into it. This is because the lake causes underflow water to spring up in the surrounding area, such as at Kaminokoike Pond. The underflow water at Kaminokoike Pond gushes out at a rate of 12,000 tons per day. It is a small pond with a circumference of 220m and a depth of 5m, and the water is so clear that you can see the bottom distinctly.

The water temperature is low, at 8°C year-round, and fallen trees lie submerged in the blue water like fossils, without rotting. The sight of Dolly Varden trout with their vermilion spots swimming between them is a mysteriously beautiful spectacle.
