Nestled in the heart of the North Japanese Alps, the Kurobe Gorge Railway offers one of Japan’s most spectacular rail experiences. This tourist train winds through deep gorges, crosses vertiginous bridges and runs along an emerald river, revealing a wild landscape otherwise inaccessible without demanding hikes. Whether you travel in the spring to admire the young foliage, in summer for the cool mountain or in autumn for the flamboyant koyo, this detailed guide takes you step by step to organize your excursion on the Kurobe Gorge Railway, book your tickets and optimize your itinerary.
Presentation of the Kurobe Gorge Railway
The Kurobe Gorge Railway, also known as Kurobekeikoku Tetsudo, is a tourist line from Unazuki to Keyakidaira in Toyama Prefecture. Originally built to support the construction of hydroelectric dams in the Kurobe Valley, it is now open to travelers looking for spectacular alpine landscapes.
Long about 20 kilometers, the line crosses one of Japan’s deepest gorges. The open cars, characteristic of the train, allow you to take full advantage of the panorama. The experience is immersive: one feels the wind’s breath, the temperature variations and the impressive proximity of the steep cliffs.
Unless you plan a sustained alpine hike, it is the easiest and most comfortable way to get to the heart of the mountains in the north of the country.
Map and route of the line

The journey starts at Unazuki Station, easily accessible from Toyama. The train then climbs up the valley following the Kurobe River to Keyakidaira, the end of the line.
The main stations include:
Unazuki
Kuronnagi
Kanetsuri
Keyakidaira
Explore Keyakidaira and its surroundings
The Keyakidaira terminus is an ideal starting point for a short hike. Several trails allow to admire spectacular views of the gorge.
One of the most popular experiences is walking to a thermal spring in the nature. Swimming in an onsen surrounded by mountains offers an exceptional moment of relaxation after the journey by train.
Photographic enthusiasts will find unique perspectives here on the suspended bridges and the river.
How to access Unazuki
From Toyama you can reach Unazuki Onsen Station via the local Toyama Chiho Railway. The journey takes about 1 hour.
Toyama is served by the Hokuriku Shinkansen, connecting Tokyo, Nagano and Kanazawa. This excursion is therefore easily integrated into a route including the Japanese Alps, the Tateyama Kurobe Alpine Route or the Hokuriku region.
If you are staying in Kanazawa or Takayama, a day trip is possible, provided you plan your connections well.
Each stop offers access to hiking trails, panoramic bridges or thermal springs. The map of the Kurobe Gorge Railway highlights the many metal bridges hanging over the turquoise river, as well as the tunnels dug into the rock.
The entire journey takes about 1 hour 20 minutes in each direction. It is possible to get off at an intermediate station and then resume a subsequent train, provided you have a valid ticket.
A spectacular immersion in the Japanese Alps
The Kurobe Gorge is renowned for its steep landscapes, dense forests and impressive reliefs. Over the course, the train crosses more than 20 bridges and many tunnels.
In autumn, usually from late October to early November, the valley becomes a red, orange and gold mosaic. This is the most popular period and it is advisable to arrive early in Unazuki to avoid long queues.
In spring, snowmelt feeds the river, providing powerful flow and striking contrasts with rising vegetation. In summer, the freshness of the mountains is an excellent escape from the heat of large Japanese cities.
In winter, the line is usually closed due to climatic conditions.
The different types of wagons
The Kurobe Gorge Railway offers several categories of seats:
The standard cars open, very appreciated for the unobstructed view and authentic atmosphere
Semi-closed cars, providing partial protection against rain and wind
The first class cars, more comfortable, with front facing seats and panoramic windows
The surcharge for the first class remains modest compared to the standard ticket, and may be relevant if you travel outside the busy periods. However, for an immersive experience and photos without glass, open cars remain a preferred choice.
Hours and operating period
The line usually runs from April to November. Schedules vary according to season, with a higher frequency during the high season of autumn foliage.
It is recommended to consult the official timetables before your visit, especially if you integrate this tour into a wider itinerary including Takayama, Kanazawa or the Japanese Alps.
Reservation and purchase of tickets
One of the advantages of the Kurobe Gorge Railway is the relative simplicity of purchasing tickets.
You can:
Buy a ticket the same day at Unazuki station
Book online via booking platforms
Use the company’s official website
During peak periods, especially during the koyo, advance booking is strongly recommended.
The price for a standard seat between Unazuki and Keyakidaira is approximately 1,980 yen. The supplement for the first class is fixed regardless of the journey.
Japan Rail Pass does not cover this line as it is operated by a private company.
When to visit the Kurobe Gorge Railway
The best time depends on your priorities:
Spring for green landscapes and snowmelt
Summer for mountain freshness
Autumn for the spectacular foliage
Autumn remains the most sought after season. Weekends can be very popular. If possible, choose a weekday.
Check weather forecasts: in clear weather, colours and visibility are incomparable.
Exploring the Kurobe Gorge Railway is an intense immersion in the heart of the Japanese Alps, in a spectacular setting shaped by the river and the mountains. Easy access, affordable and memorable, this excursion is an ideal step to enrich a route in the Hokuriku region or the Northern Alps. By carefully planning your visit and choosing the right season, you will experience one of the most beautiful panoramic experiences by train in Japan.
