August 26th, 2014

Lake Onneto

Lake Onneto (オンネトー) in Akan Mashu National Park (阿寒摩周国立公園) is a dammed lake born by an eruption of Mt. Meakan (雌阿寒岳) in Ashoro town. The Onnneto means "Aged Marsh" or "Large Marsh" in Ainu language. The perimeter of the lake is about 2.5 km, and the maximum water depth is about 10 m, and the lake is not so large. The Lake Onneto is one of the three major secret lakes together with Lake Ocotanpe (オコタンペ湖) and Lake Shinonome (東雲湖) in Hokkaido. Because colors of water look azure blue and emerald green depending on seasons, places, directions of wind and weather, the lake is called "Goshikinuma (五色沼 * Marsh turning into 5 colors)", and it is said that the colors of the water is the most beautiful in Hokkaido. It seems to look beautiful in particular if weather is bad. The water turning into 5 colors is acid with ph 6, and fishes can not inhabit, but only Uchida Crawfish (内田ザリガニ) and Yezo Salamander (エゾサンショウウオ) inhabit in the water. Creatures seem to be able to adapt to harsh environment.

The Lake Onneto is in Ashoro town, but the distance is around 50 km away from the center of the Ashoro, and the distance is around 20 km away from Akako Onsen Resort (阿寒湖温泉街), so a convenience store is not built around here. But Onneto-Chaya (オンネトー茶屋) is around here, and tourists can have a lunch there. There are the Mt. Meakandake, the Mt. Akanfuji, the Lake Onento, Onneto Observation Deck (オンネトー展望デッキ), Onneto Hot Falls (オンネトー湯の滝), Onneto Campsite (オンネトー野営場), Onneto Lookout (オンネトー展望台), Meakan Onsen (雌阿寒温泉), Kagami Swamp (鏡沼), Ao Swamp (青沼), Aka Swamp (赤沼) and Rawanbuki Field (ラワンブキ観賞ほ場) around here, and trails and walking paths are built, too.

Story of Onneto
Lake Onneto

In case of hiking, the visitors should bring water of 500 ML-1 L. I regretted not to drink the water. You had better bring an insect repellent because a lot of gnats or horseflies try to bite your skin in a summer. In addition, bears seem to appear, so you had better bring bear-avoiding bells, too. You should prepare extra underwears and work gloves, and I sweated gallons. You may be tired because of a difference of elevation, so you had better wear comfortable shoes. In a winter, the road is cloed, so visitors can make a snowshoe trip from the Meakan Onsen. I think that the snow lake is beautiful, too.
