The Kurobe dam (黒部ダム) or Kuroyon dam (黒四ダム) , Japan's largest dam, is on the Kurobe River in Toyama Prefecture on the island of Honshu. It generates electricity for the Kansai Electric Power Company. It stands 186 m high and holds 200 000 000 cubic meters of water. Its construction, completed in 1963 at a cost of 51 300 000 000 yen, claimed the lives of more than one thousand people.

A film, Kurobe no Taiyō (黒部の太陽; lit:Kurobe's sun), starring Yujiro Ishihara (the late brother of Tokyo governor Shintaro Ishihara), recounts the drama of the project.
