Takahara River

The Takahara River (高原川) 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.
