What is the Kurobe Dam?
The Kurobe Dam is one of Japan’s largest arch dams, located in the Northern Alps of Toyama Prefecture.
It was built at an elevation of 1,500 meters, and the dam body reaches a height of 186 meters.
Completed in 1963, it was constructed to generate electricity by harnessing the rapid flow of the Kurobe River.
Today, the Kurobe Dam is more than infrastructure — it’s a popular tourist destination visited by over one million people each year.
In particular, the sightseeing water releases held from late June to mid-October are breathtakingly powerful.
Rainbows sometimes appear during the releases, delighting visitors.
