Details Since the former Ashio copper mine was situated in the upstream area of Kusaki Dam, there was concern about the inflow of heavy metals such as copper and zinc to the reservoir. For that reason, Kusaki Dam installed water quality analysis facilities in the management office, and they are monitoring water quality such as the heavy metal concentration in the dam reservoir every single day.

He just used his mouth to hold the brush and started painting of flowers and other stuff available nearby. As his paitings were full of passion but soft feeling, many viewers were astonished how vivid his paintings were. Sometimes there were chains of buses driven to this museum just to see those paintings.
