The Jinzū River (神通川, Jinzū-gawa or Jintsū-gawa or Jindzū-gawa) is a river that flows from Gifu Prefecture to Toyama Prefecture in Japan. The upper reaches of the river in Gifu are called the Miya River. It is 120 km (75 mi) in length and has a watershed of 2,720 square kilometres (1,050 sq mi).
The official name for the river is "Jinzu Gawa" (written じんづうがわ (Jinzū-gawa or Jindzū-gawa)) according to the Geospatial Information Authority of Japan and Japan Coast Guard. [1] However, the pronunciation of the name has variations, including じんずうがわ (Jinzū-gawa) and じんつうがわ (Jintsū-gawa). [2] [3]
The Jinzū River flows from a source at 1,626 metres (5,335 ft) on the slopes of Mount Kaore in Takayama, Gifu Prefecture and meets the Takahara River at the border between Gifu and Toyama Prefectures. [4] The upper reaches of the river in Gifu Prefecture are also called the Miya River (宮川, Miya-gawa). [4] From the border it flows generally north and empties into Toyama Bay on the Sea of Japan. [4] It's drainage basin covers an area of 2,720 square kilometres (1,050 sq mi). [4]
It once meandered through the city of Toyama, but the new waterway was constructed in the west of the city to avoid floods. Toyama City Hall and other governments are located on the reclaimed land of the old river.
The river was polluted with cadmium due to mining and caused the itai-itai disease in the downstream towns around World War II. [5]
The Japanese Navy cruiser Jintsū was named after this river. [6]

Itai-itai disease was the name given to the mass cadmium poisoning of Toyama Prefecture, Japan, starting around 1912. The term "itai-itai disease" was coined by locals for the severe pains people with the condition felt in the spine and joints. Cadmium (Cd) poisoning can also cause softening of the bones and kidney failure. Effective treatments involve the use of chelators to promote urinary excretion of Cd. The cadmium was released into rivers by mining companies in the mountains, which were successfully sued for the damage. Remediation efforts in the affected region have been ongoing since 1972 and were mostly complete as of 2012. Monetary costs of the cleanup have been paid for in part by Japan's national government, Mitsui Mining, and the Gifu and Toyama prefectural governments. Itai-itai disease is known as one of the Four Big Pollution Diseases of Japan.
