Two adjacent reservoirs face Milk Road (prefecture route 140). Enough parking space can be found along the road. The best season is winter. In the reservoirs, many kinds of ducks winter; Smew, Mallard, Spot-billed Duck, Shoveler, Teal, Garganey, Falcated Duck, Tufted Duck, and Pochard. In the surrounding park and forest, we can see Pale Thrush, Dusky Thrush, Long-tailed Rose Finch, Hawfinch, Varied Tit, and Rustic Bunting.
