Lake Onneto

Onneto Lake is a part of Akan National Park in Ashoro, Hokkaido. "Onneto" means old pond or big pond in the aboriginal Ainu language. The lake with a circumference of 2.5 km was created when the river was dammed up due to the volcanic eruption of Mt. Meakan-dake. Due to high acidity levels, fish can’t live in the lake but ezo salamander and crawfish can.
Since the surface of Lake Onneto beautifully changes color from light blue to green and dark blue, depending on the time of day or the season, the lake is also called Goshikinuma. Along with Okotanpe Lake and Shinonome Lake, the lake is considered one of the three major mystery lakes in Hokkaido. For this reason, there are a lot of trails and camping sites along the banks.
In the southeast part of the lake, 800m tall and 300m fall "Onneto Waterfall" is located. This waterfall is unique because it is made of manganese oxide. It is an Important Natural Monument and had been selected as one of the Japan's top 100 geological features. Be sure to drop by if you visit Onneto.
