Viewing Kurobe Dam

Dam Observation Deck

The Observation Deck offers views of the dam, of course, but also of the Northern Japan Alps. From Kurobe Dam station there is an underground passage that climbs 220 steps, taking about 10 minutes to reach the deck. The deck is also accessible via an exterior staircase that allows you to enjoy changing views as you climb. You can see a pulley and bucket that was used to carry concrete during construction, half way up this route. There is a spring on the deck providing cool fresh water for your refreshment.

Water Discharge Observation Deck

There is a barrier free observation point, suitable for wheelchair and stroller users, close to the discharge area.

New Observation Area

You can see the water discharge right before your eyes at the new observation area, accessible from the staircase below the discharge viewing stage.

Dam Crest

You can appreciate the magnitude of the dam by taking a leisurely stroll on its crest.

Wheelchair users and those concerned about walking have no need to worry.

When negotiating the stairs and vehicles at each station, please feel free to contact a member of staff for assistance. If you have any other concerns, please do not hesitate to contact us.

Attractions around Kurobe Dam

Dam Lake Trekking

Enjoy a leisurely walk along this mountain path beside the lake. The route crosses a suspension bridge in addition to a paved promenade and sloped sections. The 3-kilometer course takes about 1 hour to walk. Proceeding further along the path you will find a large 800- or 1,000-year-old tree, also named “Kurobe”. Why not go and receive the power of this tree, which takes about 8 adults to encircle hand in hand.

Enjoy the Trolley Bus

In the middle of the trolley bus route connecting Ogisawa Station and Kurobe Dam Station, you can see a fracture zone, illuminated by a blue light. Although the trolley bus covers this 80-meter section in no time, this was the hardest part of the tunnel’s construction. A feat of civil engineering construction in its time, the tunnel finally broke through after seven months of struggle.

About the “Fracture Zone”

In May 1957, about 1,600 m from the tunnel entrance, 660 liters/second of ice cold groundwater and a large amount of sediment gushed into the tunnel. In this fracture zone, fine cracks in the bedrock had created a soft strata that stored the groundwater. The excitement and drama of the tunnel breakthrough here was captured in novel and film.

Kuroyon Memorial Room

Located on the 3rd floor of the Kurobe Dam Rest House, this room exhibits construction materials and models detailing the construction of the dam. Additionally there is a continuous screening of the movie “Kuroyon Story”. (Entrance is free of charge)
