Camp Site Onneto Campground

Onneto Campground
Camp on banks of the enchanting Lake Onneto.

In the Ainu language, "Onneto" translates to "old, revered marsh." Lake Onneto is strikingly clear and its cerulean waters fluctuate in color, earning it another name, Goshikinuma ("five-colored marsh"). The reflection of Mt. Me-akan and Mt. Akan-fuji across its surface is one of the most spectacular sights in the park. A walking path fringes the lakeshore, and in the early summer, it is speckled in color with blooming rhododendrons and other wildflowers.

Onneto Campgrounds is located directly adjacent to Lake Onneto with trailhead access near the parking lot. About 1.7 kilometers from the camp site, you will also find the Onneto Yunotaki Falls where two streams of hot 40°C water flows from a height of 30 meters and blackish-brown manganese oxide deposits are left along the water's path. As the only place on earth where you can see manganese oxide above ground, this waterfall has been designated a Natural Monument.

Message from the Facility
The Onneto Campgrounds are situated right in the beautiful forest on the shores of Lake Onneto. My favorite thing about the lake is how the night sky gets reflected upon the water’s surface. It is filled with so many stars that it seems like they could come raining down any minute. I also recommend setting up a campfire and listening to the relaxing sound of the wind passing through the forest. The campgrounds serve as the perfect base for climbing Mt. Me-akan, one of the One Hundred Mountains of Japan, as well!
