Imuta Pond

Japanese: 藺牟田池 - いむたいけ
Imuta Pond

Imuta is a crater lake of the Imuta volcano in Imuta, Kedoin-cho, Satsumasendai City, Kagoshima Prefecture. It is surrounded by mountains around 500 meters above sea level, such as Mt. Katashiro, Mt. Sanno, Mt. Funami, and Mt. Iimori. It is a nearly circular lake basin with an area of ​​about 0.6 square kilometers, a water surface elevation of 295 meters, and a diameter of about 1 kilometer. The maximum depth is about 3.5 meters, but the western third of the lake has become a marshland due to peat-forming plants such as reeds and Ampelia japonica, and floating islands can be seen here and there. Water shields float on the surface of the water, and the water is brown in color, making it classified as a humus-nutrient lake. The peat-forming plant community is a nationally designated natural monument. The surrounding area is also a prefectural natural park area. Nearby is the secluded Imuta Onsen, and on the west bank is the Kagoshima Workers' Rest Village. There is a bus service from JR Kawauchi Station. Imuta Pond became a Ramsar site in 2005.

鹿児島県薩摩川内市(さつませんだいし)祁答院町(けどういんちょう)藺牟田にある藺牟田火山の火口湖。片城(かたしろ)山、山王岳、舟見岳、飯盛(いいもり)山など標高500メートル前後の山に取り囲まれている。面積約0.6平方キロメートル、水面標高295メートル、直径約1キロメートルでほぼ円型の湖盆である。最大水深は約3.5メートルであるが、その西側3分の1は、ヨシ、ネビキグサ(アンペライ)などの泥炭形成植物により湿原化し、随所に浮島もみられる。水面にはジュンサイ類が漂い、水色は褐色で腐植栄養型の湖沼に分類される。泥炭形成植物群落は国指定天然記念物。またこの付近一帯は県立自然公園地区となっている。近くにはひなびた藺牟田温泉もあり、西岸には鹿児島勤労者いこいの村が設けられている。JR川内駅からバスの便がある。なお、藺牟田池は2005年(平成17)に、ラムサール条約登録湿地となった。
