Kurobe Dam Complete Guide (Toyama Prefecture) | Access, Highlights, Tourist Water Discharge, Clothing, Model Courses Thoroughly Explained
Kurobe Dam, located in the Kurobe Gorge surrounded by the steep mountains of the Northern Alps in the eastern part of Toyama Prefecture, is a massive dam boasting Japan’s greatest height. The construction work carried out from 1956 to 1963 was called “the construction project of the century,” and is known as a historical structure that was completed despite claiming 171 lives. The Kurobe Dam, with its overwhelming scale of 186m in height, 492m in crest length, and a total water storage capacity of 203 million cubic meters, is not merely a hydroelectric power generation facility, but serves as a major tourist attraction on the Tateyama Kurobe Alpine Route that traverses the Chubu Mountain National Park, attracting over one million domestic and international visitors annually as a spectacular natural scenery spot.
Basic Information and History of Kurobe Dam
Construction History Known as “the Construction Project of the Century”
Kurobe Dam is a hydroelectric power generation-exclusive dam constructed by Kansai Electric Power to resolve Japan’s postwar power shortage. At the time of construction, access to the Kurobe Gorge, called the unexplored region of the Northern Alps, was extremely difficult, and the tunnel excavation work for material transportation encountered crushed zones, with grueling work continuing in battle with massive groundwater.
This construction project, which was featured in the film “The Sun of Kurobe” and NHK’s “Project X,” involved a total of 10 million workers, took 7 years, and was completed at an enormous cost of 51.3 billion yen at the time (equivalent to several hundred billion yen in today’s value). Since its completion on June 5, 1963, Kurobe Dam has continued to support Japan’s power supply.
Specifications of the Dam with Japan’s Greatest Height
Kurobe Dam’s main specifications are as follows:
- Type: Arch concrete dam
- Dam height: 186m (Japan’s highest)
- Crest length: 492m
- Dam volume: 1.58 million cubic meters
- Total storage capacity: 203 million cubic meters
- Power plant output: 335,000 kW (Kurobe River Fourth Power Station)
The arch dome overflow type structure realizes a massive dam with minimal concrete by distributing water pressure to the rock formations on both banks. This technology is evaluated as world-class.

Attractions and Ways to Enjoy Kurobe Dam
Spectacular Tourist Water Discharge | Thrilling Power of Over 10 Tons Per Second
The greatest attraction of Kurobe Dam is the tourist water discharge releasing over 10 tons of water per second. Water forcefully released from a height of 186m creates a beautiful rainbow on sunny days, and this sight is called “Japan’s finest scenery.”
Basic Information About Tourist Water Discharge
- Period: June 26 to October 15 (varies slightly by year)
- Time: 6:00 a.m. to 5:30 p.m. (varies by period)
- Discharge volume: 10 to 15 tons per second

Best Timing to See a Rainbow
For the rainbow created by tourist water discharge, the sun’s position is crucial. Late morning (around 9:00 a.m. to 11:00 a.m.) is said to be the time when rainbows are most likely to appear. On clear days with little wind, you may even see a double rainbow.
Touring the Observation Platforms of Kurobe Dam
Kurobe Dam has multiple observation platforms, each offering views of the dam from different angles.
New Observation Platform (Kurobe Dam Station side)
Approximately 5 minutes on foot from Kurobe Dam Station. An excellent viewpoint for looking down at the dam from the front. The tourist water discharge can be seen up close, and it is popular as a spectacular photography spot.
Dam Observation Platform (Crest)
An observation platform reached by climbing 220 steps to the crest. From an elevation of 1,508m, you can see a panoramic view of Kurobe Lake and the Tateyama Range. On fine days, a magnificent panorama of the Shiritateyama Range unfolds.
Water Discharge Viewing Stage
The spot where you can experience the water discharge most closely. You may be splashed with water, so rain gear is recommended. The powerful sound and mist-like spray cannot be experienced anywhere else.
Kurobe Lake Cruise Ship “Garve” – Lake Cruise Experience
On Kurobe Lake, you can board the cruise ship “Garve,” which operates at Japan’s highest elevation. The view of the Tateyama and Shiritateyama ranges from the lake at an elevation of 1,448m is exceptional.

Best Season for Kurobe Dam Tourism and Clothing
Charm of Each Season
Spring (Mid-April to June)
Shortly after the opening of the Tateyama Kurobe Alpine Route, the “Snow Valley” at Murodo is the main attraction.

The tourist water discharge becomes full scale, and the probability of seeing rainbows increases. Popular as a summer resort, even when the plains experience extreme heat, the area around Kurobe Dam remains cool and comfortable. Alpine plants reach their peak season, and you can fully enjoy the natural environment.
Autumn (September to Early November)
The autumn foliage season is the highlight of Kurobe Dam tourism. From late September to mid-October, rowan and Dahurian birch trees turn color, and the area around Kurobe Lake becomes dressed in autumn colors. The tourist water discharge continues until mid-October, allowing you to enjoy the cooperation of autumn foliage and water discharge.
