Lake Onneto
Learn the Secret of Hokkaido’s Lake Onneto
Located at the westernmost edge of Akan-Mashu National Park, Onneto is a mysterious lake whose name means “old swamp” or “large swamp” in the Ainu language. This beautiful dammed lake was formed when lava from an eruption of Mt. Meakan blocked the flow of the nearby Rawan River. The lake is about 2.5 km in circumference and reaches a maximum depth of about 10 meters.
One of Onneto’s most captivating features is the way its surface color changes depending on the season, weather, and viewing angle. The lake can appear as a clear blue, emerald green, or deep dark blue, creating breathtaking scenery that fascinates all who visit.
From the observation deck on the western lakeshore, you can enjoy a panoramic view of Onneto with Mt. Meakan and Mt. Akan Fuji as a stunning backdrop. Well-maintained walking trails surround the lake, allowing you to fully immerse yourself in the untouched primeval forest and the unspoiled nature of Hokkaido.
Whether you seek serene landscapes, unique natural phenomena, or a peaceful escape into nature, Onneto Lake offers an unforgettable experience in the heart of Hokkaido.
