[Junsainuma Swamp in Nanae] Water Shield Grows in Freshwater Swamp
Junsainuma Swamp (蓴菜沼) is a freshwater swamp in Nanae located in the northern part of Hakodate city, and the 3rd largest lakes in Onuma Quasi-National Park. The perimeter of the swamp is about 7.3 km, and the maximum water depth is 4.6 m. As its name suggests, the swamp was named after harvesting the water shield. The water shield means "The Junsai" in Japanese. It is located in the western part of National Route 5, walking paths and spring water called Gozensui spring (御膳水) as sightseeing spots are in Junsainuma Swamp Area. But it seems that the spring water is not drinkable. Smelt pond fishing can be enjoyed in a winter. A parking lot, a public restroom and buckwheat noodle restaurant "Gozensui" are built at the site. The buckwheat noodles are popular, too. Admission free. The parking lot is free of charge.
Onuma Quasi-National Park
Onuma Quasi-National Park (大沼国定公園) is a quasi-national park at the foot of Mt. Komagatake (駒ヶ岳) in the southern part of Hokkaido, and is between Nanae town, Shikabe town and Mori town. Its area is 9,083 ha. The park has been designated as the quasi-national park since 1958, and 2 million tourists come. It consists of the Mt. Komagatake of 1,131 m elevation, an active volcano, Lake Ounma (大沼湖), Lake Konuma (小沼湖), Junsai Swamp (蓴菜沼), and beautiful scneries are highlights. The Onuma Quasi-National Park has been chosen as one of The 3 New Views of Japan (新日本三景) together with Miho-no-Matsubara (三保の松原) in Shizuoka prefecture and Yabakei (耶馬渓) in Oita prefecture since 1915. It is also famous for fall foliage, and has been chosen as one of The 100 Best Fall Foliage Spots in Japan (日本紅葉の名所100選). When the Mt. Komagatake erupted from 50,000 to 30,000 years ago, a river was dammed by flowing mud flood, and those lakes were created. Wetlands have been registered under the Ramsar Convention since 2012, and wild waterfowls such as Goose and Duck rest their wings on the surface of the lake. Article is here
Look of Junsainuma Swamp
Wooden paths and a small gazebo were supposed to be built along the lakeshore, and the Gozensui spring were supposed to gush out at the gazebo. When I visited here, the wooden paths were broken, and entering the wooden paths was prohibited. So I suppose that The Junsainuma may be seen only from the lakeshore near the public restroom.
