Kurobe dam Toyama

There are about 3,000 dams in total in Japan. The water stored in dams is sometimes released to control floods or to maintain rivers.

But it’s not often that you get the chance to see a dam releasing water up close.

Every year, the Kurobe Dam in Toyama Prefecture, the tallest dam in Japan, releases water for a limited time. The Kurobe Dam’s water discharge is so large in scale that many tourists visit the dam to see the powerful sight.

This article is about the Kurobe Dam and its tourist water discharge event.


About Kurobe Dam

The tallest dam in Japan, Kurobe Dam

The Kurobe Dam in Toyama Prefecture is an arch-shaped dam built by Kansai Electric Power Company in 1963.

Built over seven years by 10 million people, the Kurobe Dam is the largest dam in Japan and is 186 metres high and 496 metres wide.

The construction of the Kurobe Dam was so difficult that it was even made into a film.

It currently generates enough electricity to power around 250,000 homes a year.


Kurobe Dam is a tourist attraction on the Tateyama Kurobe Alpine Route

The Kurobe Dam is one of the highlights of the Tateyama Kurobe Alpine Route, a mountain tourist route linking Toyama and Nagano prefectures. The Tateyama Kurobe Alpine Route is part of the Chubu Mountains National Park.

The Kurobe Dam can be visited from spring to autumn when the Tateyama Kurobe Alpine Route is open.

* In 2021, the Kurobe Dam will be open to visitors from 26 June to 15 October.


How to get to the Kurobe Dam from the Nagano side

There are two ways to get to the Kurobe Dam on the Tateyama Kurobe Alpine Route: from Tateyama Station in Toyama Prefecture, or from Ogisawa Station in Nagano Prefecture.

In 2021, the Kurobe Dam will be releasing water for tourism from 26 June to 15 October.

The water discharge event is for tourists, while the water release for power generation takes place in a separate area. It is quite a sight to see the water being released from the height of the 185 metre embankment, the highest in Japan, at a rate of over 10 tonnes per second.

You can see the massive water discharge up close from the new observation square and from the Rainbow Terrace below it.

Kurobe Dam has an artificial reservoir, called Lake Kurobe, which is covered with thick ice during the winter months, but during the summer and autumn months when it is open, you can take the “Tourist Boat Garbe” for a round trip around Lake Kurobe with views of the Tateyama Mountain Range.
