The Toga Dam is a gravity dam on the Togagawa River (a tributary of the Shō River) near Omaki village about 11 km (6.8 mi) southeast of Shogawa in Toyama Prefecture, Japan. It was constructed between 1941 and 1943. The dam diverts water to the 17.6 MW Omaki hydroelectric power station 4.3 km (2.7 mi) to the west on the Shō River. It was commissioned in 1944.^[1]
