[Lake Onneto in Ashoro] Onsen and Hot Falls Can Be Enjoyed, too
August 26th, 2014
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. As for the Lake Onento, Cherry blossoms can be enjoyed in a spring, fresh green can be enjoyed in a summer, fall foliage can be enjoyed in an autumn, especially, the lake is famous as one of best places to see the fall foliage in Hokkaido.
4 walking paths, Western Lake Onneto Course (オンネトー西コース), Eastern Lake Onneto Course (東湖岸コース), Onneto Hot Falls Course (湯の滝コース) and Meakan Onsen Course (雌阿寒温泉コース), are built, the Western Lake Onneto Course is about 2.2 km from the Onneto Observation Deck via the Onneto Lookout to the Onneto Campsite, and it takes about 40 minutes on foot. The Eastern Lake Onneto Course is about 1.9 km from the the Onneto Campsite to an entrance of the Lake Onneto, and it takes about 40 minutes on foot. The time it takes to go a round trip is around 80 minutes. The Onneto Hot Falls Course is about 1.4 km, and it takes about 30 minutes on foot. As for the Meakan Onsen Course, I do not know it in detail. 2 trails, Meakan Onsen Course (雌阿寒温泉コース) and Onneto Course (オンネトーコース), are built, and the Meakan Onsen Course is about 3.3 km from the Meakan Onsen to the Mt. Meakandake, and it takes about 2 hours on foot. The Onneto Course is abouy 4.2 km from the Onneto Campsite to the Mt. Meakandake, and it takes 2.5 hours on foot. By the way, Story of Onneto (オンネトー物語), an experiencing nature event, is held in late September.
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.

Lake Akan (阿寒湖) is a caldera lake in the northern part of Kushiro city, and the Akan means "Immovable" in Ainu language. In Akan Mashu National Park, the perimeter of the lake is about 25.9 km. The maximum water depth is 45 m. The lake is well-known for growing Lake Ball (Marimo). Old Lake Akan was dammed by eruptions of Mt. Oakandake (雄阿寒岳) 10,000 years ago, and 3 lakes, the Lake Akan, Lake Panketo (パンケトー) and Lake Penketo (ペンケトー) were born. Trees such as Yezo spruce, Abies sachalinensis, Painted maple and Mongolian oak grow naturally around the lake, and the lake side is covered with the primeval forest. 24 types of wild animals such as Brown bear and Yezo deer and 65 types of wild birds such as Black woodpecker inhabit, and the lake has been designed as a wetland under the Ramsar Convention since 2005.
