Akkeshi-ko (厚岸湖) is a brackish lake near Akkeshi in Hokkaidō, Japan. The wetlands of Lake Akkeshi and Bekanbeushi Marsh (別寒辺牛湿原) have been designated a Ramsar Site.
Lake Akkeshi, 11m deep at its deepest point, is fed by the Bekanbeushi River (別寒辺牛川) and adjoins Akkeshi Bay. It is surrounded by salt marsh, fens, and bogs.
Since the lake does not freeze, Whooper swans and ducks winter there. The White-tailed Eagle and Steller's Sea Eagle also visit. There is a 381ha Japanese Crane sanctuary.
Sustainable use 
Fishing and the aquaculture of oysters and clams occur in the lake.
