Takahara River (original) (raw)

The Takahara River (高原川, Takahara-gawa) has its source at Mount Norikura in the northern part of Gifu Prefecture, Japan, and flows into Toyama Prefecture, where it joins with the Jinzū River. It is a Class 1 River. The river was polluted with cadmium due to mining at the Kamioka mines (神岡鉱山 Kamioka Kōzan) and caused the itai-itai disease outbreak in downstream towns that began shortly before World War II.
