Site description Lake Komukeko consists of three major water bodies, and the largest part is connected to the sea by an artificial stream. Vast wetlands appear when tide is low. The sea and the lakes are divided by a coastal sand bar. Salicornia europaes is pretty in autumn on the lakeshore. The lake is surrounded by reed beds and outside of the reed beds are farmlands and woodlands. Two low water rivers flow into the lake. There is a floodgate at the entrance of Lake Shibunotsunai, but when there are storms, there is seawater intrusion into the lake. The lake is also surrounded by reed beds and farmlands.
