Lake Onneto
Lake Onneto is a small, picturesque lake at the foot of Mt. Meakan, in the westernmost region of Akan-Mashu National Park. Its beauty and isolation attract many visitors. Lake Onneto is known as the “Lake of Five Colors.” Depending on the weather conditions and time of day, the water appears to change in color from light blue through shades of green to dark blue.
On the road that winds along the western shore of Lake Onneto, there is a wooden observation deck with unobstructed views of the water. From here, you can also see Mt. Meakan and Mt. Akanfuji in the background. There are four easy walking paths that start at the lake, with varying scenery and animal and plant life.
Down the road from the observation deck parking lot is Onneto Campground. The campground is a good base for the challenging hike up Mt. Meakan. It is open from June to October, when the road is accessible, and is equipped with a restroom and field kitchen.
Please be aware that in order to protect the lake’s ecological environment, canoeing, swimming, and other water sports are not allowed.
