Kurobe Gorge is an Unexplored Region That Can Only be Reached by Trolley Train!

The Kurobe Gorge trolley train runs along the Kurobe River from Unazuki Station to Keyakidaira Station in Kurobe City. The tracks span 20.1km, and it takes about 1 hour and 20 minutes to traverse it one way. There are many highlights of Kurobe Gorge along this railway! This guide will introduce you to spots where you can fully enjoy the unexplored wilderness and a hidden hot spring. Then, the hot spring resort "Unazuki Onsen," which makes a great vantage point for seeing the vast nature of Kurobe Gorge, will also be introduced. Please enjoy it along with your trolley train trip.

An Unexplored Region Discovered Due to the Construction of Power Plants on the Kurobe River: The History of the Kurobe Gorge and Railway

The Kurobe Gorge Railway is affectionately known as the trolley train. There is a long history before trains started running in the unexplored area of Kurobe Gorge. This area, which was off-limits to people in the past, has a steep river and receives plenty of rainfall, making it a suitable topography for building hydroelectric power plants. In 1923, the trolley train tracks were laid to serve as a railway for transporting construction materials. Although the construction work was extremely challenging, several power plants were successfully built up the Kurobe River, including Yanagawara, Kurobe River No. 2, Kurobe River No. 3, and Kurobe River No. 4. Among them, the Kurobe River No. 4 Power Station is commonly called “Kuroyon,” and is still talked about as one of the greatest construction projects of the century. The trolley trains used to transport materials continued to run to serve the local people in their day-to-day lives, but gradually, tourists began to ride them as well. In 1953, the trolley train transitioned to passenger transport under the name "Kurobe Railway," and tourism in Kurobe Gorge began to prosper.

Kurobe Gorge, One of Japan's Most Famous V-Shaped Gorges

Kurobe Gorge, one of the most famous V-shaped gorges in Japan, is deeply carved into the Northern Alps. It is also one of Japan's Three Major Gorges and one of Japan's Top 100 Unexplored Regions. The Kurobe Gorge originates from Mount Washiba in the center of the Northern Alps and forms a steep, deep V-shaped gorge in the upper and middle reaches of the Kurobe River, which is 86 km long and flows down 3,000 m in altitude.

Although the area is covered with deep snow in winter, it is crowded with tourists from mid-April to the end of November when the trolley train operates. The untouched nature and seasonal valleys seen from inside the car are truly spectacular views, especially during the autumn leaves when the entire canyon turns bright red and yellow, which is the best season.

A Trolley Train Running through Nature

A trolley train runs through the magnificent valley from mid-April to the end of November. There are two types of passenger cars, and it's fun choosing one to match your mood and reason for travel.

Regular passenger car
An open type with no windows. The rows of seating are for four people each. Fares only. You can feel the wind blowing through the car, listen to the murmuring of the Kurobe River, and enjoy the spectacular scenery.

Relaxing passenger car
A type with windows that can be opened and closed. The seats are convertible cross seats that seat three people in a row. Regular fare plus 530 yen. You can enjoy your trip in peace, and depending on the time of day, there are barrier-free passenger cars with large entrances and exits.

All seating capacity is fixed, so everyone can sit and enjoy the trip. The canyon can be chilly even in summer, so if you're going to take a regular passenger car, it's best to bring a jacket!

Enjoy the Spectacular View from the Window of the Trolley Train!

The best part of riding a trolley train is enjoying the spectacular scenery from the windows! Along with the clear waters of the Kurobe River, you can enjoy fresh greenery in spring and fiery autumn leaves in autumn. On the way there, the best viewing spots are concentrated on the right-hand side in the direction of travel, so be careful where you sit. In addition, the on-board announcement will introduce you to the highlights of Kurobe Gorge. Enjoy the spectacular views while listening to the wonderful narration by Shigeru Muroi, a native of Toyama Prefecture!


Between Unazuki Station and Kuronagi Station

As soon as you leave on the first train from Unazuki Station, you'll find many things to see!

  • Yamabiko Bridge

    Yamabiko Bridge

    Immediately after leaving Unazuki Station, there is a crimson iron bridge you’ll first cross. The height above the mountain stream is about 40 meters, and when you look down from the train, you can't help but cheer! The name comes from the fact that the sound of trains crossing the iron bridge can be heard in the hot spring town, similar to an echo, or “yamabiko” in Japanese.

  • Unazuki Lake

    Unazuki Lake

    An artificial lake created by the completion of the Unazuki Dam. The emerald green surface of the lake and the great nature of Kurobe Gorge are so beautiful that it makes you want to capture it in photos. There is a suspension bridge (monkey bridge) built to allow monkeys to cross to the other side of the lake, and if you're lucky, you might even see them crossing!

  • Shin-Yanagawara Power Plant

    Shin-Yanagawara Power Plant

    The beautiful appearance reminiscent of an old European castle floating on a lake is actually a canal-type hydroelectric power plant! It was built in 1993 to replace the Yanagawara Power Plant, which was submerged due to the completion of the Unazuki Dam.

Between Kuronagi Station and Kanetsuri Station

Once you pass Kuronagi Station, the natural beauty of the valley continues!


  • Atobiki Bridge

    Atobiki Bridge

    The blue iron bridge that you cross immediately after leaving Kuronagi Station. The bridge spans the steepest valley along the line, which is about 60 meters to the bottom of the Kuronagi River! It is called "atobiki” (which means “trail behind”) because climbers instinctively stepped back due to the depth of the valley. You can enjoy the thrilling scenery from the train window!

  • Dashiroppo


    "Dashiroppo'' can be seen behind the Dashidaira Dam, which is located a little before Dashidaira Station. The top of one large mountain is divided into six towering peaks. In the calm atmosphere of the gorge, the sight of the ridge cutting into the lake looks like an ink painting.

  • Nezumigaeshi no Ganpeki (“Rat-Preventer” Cliff)

    Nezumigaeshi no Ganpeki (“Rat-Preventer” Cliff)

    A large rock wall approximately 200 m high that can be seen from the area approaching Nekomata Station! It got this name because it is so steep that even a mouse chased by a cat could not climb it and had to turn back. During autumn, you will be fascinated by the beautiful autumn leaves on the rock surface.

Get off the Trolley and Experience an Unexplored Region!

After enjoying the scenery from the train window, let's get off the trolley train! The area around Keyakidaira Station, the last stop from Kanetsuri Station, is full of attractions such as spots where you can feel the great outdoors, secret hot springs, and opportunities to walk in unexplored areas. You cannot get off the train with a round-trip ticket, so if you want to go to a spot along the way, buy a one-way ticket to the first station you want to get off at.

Around Kanetsuri Station

You can also enjoy spots unique to this unexplored region around Kanetsuri Station.

  • Kanetsuri Riverbank

    Kanetsuri Riverbank

    From Kanetsuri Station, go down the stairs heading to the Kurobe River for about 10 minutes. Enjoy playing in the water on this riverbank! Cool off in the summer by soaking your hands and feet in the cool water. A hot spring also gushes here, and you can enjoy rock baths and footbaths.

  • Kurobe Mannen Yuki Observation Deck

    Kurobe Mannen Yuki Observation Deck

    The snow that falls on Mt. Meiken piles up in the valleys due to avalanches, and winter can sometimes arrive before all the snow from the previous winter has melted, hence the name "perpetual snow.” You can see the snow-covered valley up close to the observation deck on the opposite bank. The best time to visit is from around May to early summer. It’s about a 3-minute walk from Kanetsuri Station.


Kanetsuri Station Switchback, A Rare Sight in Japan-1

Kanetsuri Station Switchback, A Rare Sight in Japan

The Kurobe Gorge has precipitous cliffs. With slopes on both sides, Kanetsuri Station is very narrow – wide enough for only one train to pass at a time – so the station uses a method called "switchback" to switch between inbound and outbound trains. From the main railway, a train first moves into a track on the side and stops. When it departs, it backs up to reenter the main line and moves along. This “switchback” system, which is one of only a few in Japan, is a must-see not only for railway fans!

Around Keyakidaira Station

We will introduce the representative spots around Keyakidaira Station.

  • Sarutobi Canyon

(As the promenade is currently under repair, travelers cannot go to Sarutobi Canyon at this time.)


  • Okukane Bridge

    Okukane Bridge

    The vermilion-painted bridge that spans the main stream of the Kurobe River offers a spectacular view of Mt. Okukane and Mt. Meiken. The impressive scenery from a height of 34 meters will take you in. The contrast between the vermillion color of the bridge and the mountains seen from the rooftop observation deck of Keyakidaira Station is a must-see.

  • Hitokui Iwa (Man-Eating Rock)

    Hitokui Iwa (Man-Eating Rock)

    When you cross Okukane Bridge from Keyakidaira Station, you will see a sidewalk carved out of a rock wall. The rock surface looming overhead looks as if it will swallow people walking, making it very impressive! It is a popular photo spot.
