Toyama Prefecture might be known among international travelers for its impressive walls of snow found in the “Snow Corridor,” but tucked just a few miles away are many more hidden gems in the surrounding area. The nearby bay provides fresh seafood Toyama is known for, and the Unazuki Onsen area inside the Kurobe River Valley is full of gorges, perfect in the summer for active adventures like rafting and canyoning. “Onsen” means hot spring in Japanese, and Unazuki Onsen is of course dotted with its namesake, full of luxe hot springs. After testing your endurance in the river rapids, Kurobe offers the chance to take a reviving soak, admire the scenery on the Torokko Train, and then sample all of the local specialty cuisine, before drifting off to the sounds of the mountains.

Born between the sea and the mountains, read on to find out about all Kurobe has to offer!

Kurobe Gorge Guide: Why This Toyama Canyon Belongs on Your Japan Itinerary

Kurobe City (黒部市) has found a little fame from the high walls of snow popular with visitors looking for some good Instagram shots, but travelers who admire the snow and then get out of town don’t even know what they’re missing.

Toyama is in the Chubu Region of Japan, in the central part of Japan’s main island of Honshu, with the western border taken up by the coast of the Sea of Japan. We can thank the sea, and especially Toyama Bay, for the abundant fresh seafood found around the prefecture! But the Unazuki Onsen area also provides Kurobe with gloriously steamy hot springs, bursting forth from the mountain crags. All this geological variation makes for deep ravines, and the rivers running through those are a great place to try canyoning. Take the Kurobe Gorge Railway’s Torokko Train around the area to explore, and we’re pretty sure you’ll be pleasantly surprised by how much fun this unassuming region can be.
 

How to Get to Unazuki Onsen (Kurobe Gorge): Trains, Times & Costs

Unless you’re already at the Toyama Airport, the easiest way to get to Kurobe is probably via shinkansen (a.k.a. bullet train), which will get you there in no time.

Taking the Hokuriku Shinkansen Line to Kurobe-Unazuki Onsen Station (黒部宇奈月温泉駅)

From Tokyo Station	2 hours 20 minutes	11,860 yen
From Kanazawa Station	35 minutes	4,020 yen
From Toyama Station	12 minutes	2,940 yen

From the shinkansen station you have to take one more train ride to get to the main Unazuki Onsen area. Cross the street to get to Shin-Kurobe Station on the Toyama Chihou Railway line, and take that for another 30 minutes or so (round-trip discount ticket: 1,100 yen). The way over is quite picturesque, including the retro train itself, so enjoy the ride! You’ll eventually want to get off at Unazukionsen Station.

(Note: it’s a bit confusing, but the shinkansen station where you transfer is “Kurobe-Unazuki Onsen Station”, and your final destination is just “Unazukionsen Station”.)

From Toyama International Airport, the easiest route is just to take the airport bus to Toyama Station, and then go the shinkansen route from there. The whole trip should cost you about 3,370 yen, although all of these prices are subject to change.

To Truly Enjoy the Village of Unazuki Onsen, Go for a Ryokan

When you’re spending time in a little Japanese town like this, it’s the perfect opportunity to stay at a local ryokan-style traditional hotel. Ryokan are set up to help you make the most of the nearby hot springs, local gourmet specialties, and beautiful views!

Unazuki Onsen Togen Ryokan

During our visit, we lived it up by staying the night at Togen Ryokan, a ryokan set up for convenient access when touring Unazuki Onsen. Not wanting to waste any chances to enjoy Kurobe to the fullest, we took advantage of the private open-air baths available for rent, and the premium kaiseki ryori multi-course meals on offer. It was lots of fun getting to try all the local specialties in Toyama; we wholeheartedly recommend it. 

If you’d like to see for yourself what Togen Ryokan is like, they have a variety of rooms available. Some come with standard beds, and others are like this Japanese-style tatami room, made for families or groups, with lots of places to sit and a great view of the river. If you’re still doubting the comfort of these rooms, just know that most have fragrant tatami floors, 70% of them come equipped with state-of-the-art massage chairs, and all of them have yukata available in a few different sizes, for relaxing in around the hotel. We were certainly pretty comfortable!

Why Choose a Ryokan? Reason #1:
Enjoy your own private hot spring bath!

Ryokans often offer what are called “kashikiri onsen” (貸切温泉), literally hot springs for rent, where you can lounge in the luxurious hot water away from the rest of the guests. If bathing with strangers still makes you nervous (although you really shouldn’t worry about it in Japan), or you just want to spend some nice one-on-one time with a special someone, make sure you reserve your time slot for the kashikiri onsen as soon as possible. They’re also a good option for those of us with very obvious and hard-to-conceal tattoos, since tattoos are often frowned upon (or even banned) at Japanese onsen.

Togen Ryokan has three of these private baths available to rent, all for no additional charge.  The water here is mildly alkaline, which they say makes for beautiful skin post-bath! Just call the front desk to check availability, then pick up the keys and enjoy your soak.

(Available 15:00 – 22:00/7:00 – 10:00, 40 minutes at a time.)

If you want to really stretch out in a private bath, or you just want to rent one for up to eight people, check out Togen Ryokan’s larger open-air rental bath. This one requires a fee, 2,000 yen for 45 minutes, but hey, if not now then when? Treat yourself. To make sure you can reserve a spot, make your reservation at check-in.

(Available 15:30 – 23:15/6:00 – 9:45. 2,000 yen plus tax for 45 minutes. )

Why Choose a Ryokan? Reason #2:
Enjoy… the public bath!

If you want the true onsen experience, then you’ve got to spend some time in the public baths! Visiting a ryokan with hot spring facilities means you’re in for a pretty spectacular bathtime experience. Togen Ryokan has open-air baths built from hinoki cypress, and the warm wood gives off a pleasant aroma. Since the ryokan is right next to the river, you can watch the cold Kurobe River water rush by while feeling the hot spring water gently lap up around you.

In addition, there is also a boulder bath (岩風呂) and a special granite bath (御影石風呂) indoors.

(15:00 – 23:30 – rock bath open to men, granite bath open to women.
24:00 – 10:00 – rock bath open to women, granite bath open to men.)

The bath is lined with smooth stone, and the far corner has headrests letting you comfortably lie down in the water.

The ante-room provides all kinds of amenities, from nice face creams to blow-dryers. Just grab the towel from your room and you’re ready to go.

If you want to wear a colorful yukata, a little fancier than the ones provided for free, you can rent one for 500 yen. Once you’re fresh and clean and positively glowing from the hot spring water, do a yukata photoshoot!

Why Choose a Ryokan? Reason #3:
Indulge in a kaiseki multi-course meal.

Ryokan are known for offering really delicious multi-course traditional Japanese meals, so this ryokan staple is a great way to try some of Toyama Prefecture’s impressive agricultural specialties. We tried firefly squid (ホタルイカ), Toyama’s local variety of high-quality wagyu called “himi-gyu” (氷見牛), and very fresh abalone.

Top Things to Do Around Kurobe Gorge & Unazuki Onsen

Rich in clear water, fresh mountain air, and all the scenic geography to go with them, what’s the best way to explore all that Kurobe has to offer? Let us fill you in on how to check it all out.

Sightseeing in Kurobe: ① Canyoning in Kurobe Gorge

Blessed with deep canyons and hearty rivers, Kurobe has the perfect conditions for pushing yourself to the limits. Our recommendation? Canyoning. It’s an exhilarating way to explore the natural landscape.

Canyoning is something of an extreme sport, so you have to be accompanied by an expert. Canyoning tours are offered locally by J-WET Adventures, where the pros will coach you through the experience and make sure everyone has a good time. When you’re not entirely confident in your abilities, they’ll lend a helping hand and keep you safe! Read on to find out how to go canyoning yourself.

Sightseeing in Kurobe: ② Unazuki Dam Views

With so much water rushing along the Kurobe River, the dam was built as a hydroelectric power plant, to take advantage of the river’s energy. Unazuki Dam took years to build, and after a while the construction workers started to settle down nearby, breathing life into the Unazuki Onsen area. You could say that the town is now there thanks to the dam!

Walking to see the impressive dam is a 2.7 km (1.7 mile) walk from Unazukionsen Station (Google Maps), but you can also skip the trek and get a great view right from your seat on the Torokko Train that passes by.

Unazuki Onsen is also home to an aqueduct bridge, designed 90 years ago by the famous Japanese architect Bunzo Yamaguchi.

Sightseeing in Kurobe: ③ Kurobe Gorge Railway’s Torokko Train

When admiring the scenic views of Kurobe, you can’t miss the local Torokko Train. It gives you access to all the spots in Kurobe that you can’t even drive to, letting you see the hidden gems of the area.

This railway was built in 1923, and was originally used to carry cargo around the area, but opened for general passenger use after 30 years in 1953. The history of the shift from freight train to leisure railway is actually kind of an interesting story. While working on dam construction along the river, workers would ride the railway with the cargo to get to the construction sites. Looking around at the scenery while they rode, these construction workers happened to lay eyes on some particularly picturesque views, noting how beautiful the lay of the land was. These comments made their way to the wealthier residents of Kurobe, eventually becoming a topic of local gossip. The original cargo train was absolutely not set up for passengers, making it fairly dangerous, but the rumors of the scenery’s beauty rose to such a fever pitch that some of the upper class started to say “I don’t care if I die, I just have to see the scenery once in my life!” From that point, the area became a sightseeing destination. With such strong desire to gain access to the Torokko Train, starting so many years ago, it seems like the railway has always been the best way to view the local scenery.

Route Map from Unazuki Station to Keyakidaira Station

The Torokko Train runs a set number of times each day, so it’s a good idea to think about how you’re going to allot your time before you hop on (check the official timetable). The time between each of the stations is about 20 to 30 minutes, and the price of tickets depends on which kind of car you ride in. We recommend riding in one of the open-air passenger cars, where a one-way ticket from Unazuki Station to Keyakidaira Station will run you 1,980 yen (or 990 yen for children).

A straight shot from Unazuki Station to Keyakidaira Station lasts about an hour and ten minutes, but you can get off at each of the stations in between, and make a whole sightseeing day trip out of it. Let us tell you about some of the most beautiful natural scenery and onsen, and the best photo spots, you’ll find at each of the Torokko Train’s stations.

*Due to damage from the 2024 Noto Peninsula Earthquake, a portion of the Torokko Train route is currently out of service. While the railway works to restore service, passengers can still enjoy the ride from Unazuki Station as far as Nekomata Station.

① Unazuki Station (宇奈月駅)

Before you even get on the train, there are some cool spots around Unazuki Station! 

Just a five-minute walk from the station is the Yamabiko Observation Deck, where you can see the orange train and red bridge gleam in the sunlight, as the train passes through some lovely natural scenery. (If you’re carrying around any suitcases or heavy luggage, there are some lockers at the train station that we recommend you use to stash your bags first thing.)

② Kuronagi Station (黒薙駅)

As we mentioned above, the Unazuki Onsen area is of course known for its onsen, or hot springs. Water reaching temperatures above 90°C (194°F) gush forth from crevices in the ground. Near Kuronagi Station, you’ll find “Kuronagi Onsen” where you can soak in the steaming water while watching the river cut its way through the natural scenery. (Near Kuronagi Station you’ll also find Atobiki Bridge, which crosses Kurobe Gorge at its deepest and steepest point.)

Kuronagi Onsen, an outdoor open-air hot spring.

One thing to know about Kuronagi Onsen: it’s a mixed-gender hot spring! You’re totally welcome to wear a swimsuit in the water, if you feel more comfortable that way, but there will also be people in the nude there. If you’d prefer separate-gender hot springs, there are some indoors at the small ryokan next door.

(Kuronagi Onsen day pass: adults 700 yen, children 300 yen.)

Atobiki Bridge (後曳橋), seen over the seemingly bottomless valley.

③ Kanetsuri Station (鐘釣駅)

Near Kanetsuri Station you’ll find a river beach where you can dip into the running water and hang out on the sand, so it’s especially worth a stop in the summer. Along the river’s edge there are even spots where onsen water bubbles up, meaning you can surround one with some rocks and make yourself your own little private hot spring! (This area is just for local lodgers after 16:00.)

This station is also where you’ll find the Kurobe Mannen Yuki (万年雪), or “perpetual snow” bank.

Kurobe’s perpetual snow… also known as the “tiramisu”!

This time around, the river had flooded from heavy rain and water levels were too high for us to explore the river’s beach. Luckily, we still got to see the Kurobe Mannen Yuki, a snowbank that sticks around even through the heat of summer. The dust and debris that falls onto the snowbank really does look a bit like cocoa powder, doesn’t it? Stare long enough, and it starts to look good enough to eat… can you imagine a real tiramisu that big?

④ Keyakidaira Station (欅平駅)

Keyakidaira Station is the biggest of the stations inside the gorge, and inside the station building you can grab a bite to eat while you admire the view, and buy some souvenirs. All around the area are a number of spots with interesting views, and interesting names, making it a good place to take some fun pictures to remember the day by!

#keyakidaira

Our recommendation for a group photo spot is definitely right here! With the invigorating scenery of the gorge and Okukane Bridge in the background, we challenge you to take a truly insta-worthy shot.

#sarutobikyo

This spot’s name, Sarutobikyo (猿飛峡) literally means “monkey jumping gorge.” The distance between the two sides of the canyon are so close here, people have long believed that it’s where monkeys would jump across. There’s an observation platform right nearby.

#hitokuiiwa

This craggy overhang looks a little like an open mouth, making it feel like you might just get eaten up when you walk through. That’s where the name comes from, since “hitokuiiwa” (人喰岩) literally means “people-eating crag.”

#okukanebridge

The Unazuki Onsen area has three kinds of bridges: bridges for transportation, bridges for hydroelectric power, and then bridges for pedestrians. Okukane Bridge (奥鐘橋) is the third variety, and it’s there just for you to leisurely walk its length and admire the beautiful scenery of Kurobe Gorge.

#dinnerwithaview

While you’re more likely to eat lunch than dinner at Keyakidaira Station’s food court, you’ll still be able to see the scenery while you try out the local specialty of “black ramen.” After eating, head to the roof and take a moment to really appreciate your surroundings.

While riding the Torokko Train, you’ll probably notice a little tunnel following along the tracks. The train has long been used to get places that normal vehicles can’t, but that means that when winter rolls around and the train stops running, there’s no form of transportation in the area at all. Unfortunately for the maintenance workers doing their jobs at the gorge’s dams, that also cuts off standard deliveries of food supplies and newspapers.

During that part of the year, the delivery of necessary goods becomes the job of workers called “forwarders” (逓送さん). Even during the most relentless parts of winter, these forwarders hike through the tunnels all the way to their colleagues doing maintenance at the dams, carrying backpacks full of food and other supplies all the way there. Just one way, the trek takes about two hours! To this day, when winter comes, forwarders bring necessities on their own backs, hiking four hours round-trip. We have to say, thank you forwarders!

(The Torokko Train runs from April to November every year.)

Sightseeing in Kurobe: ④ Local Specialties for Foodies

When you visit Kurobe, don’t miss out on the seafood! The Kurobe region is right near Toyama Bay, where plankton is so abundant, you’ll find about 500 different kinds of fish in the area! There are also some varieties of seafood you’ll only find here, so you should definitely give them a taste.

Japanese Glass Shrimp (白エビ)

These shrimp can only be caught in Toyama Bay, which is why they’re sometimes called “The Treasure of Toyama.” When deep-fried, they make a satisfyingly crunchy snack that goes great with beer, but you can also find the small shrimp carefully peeled one by one, as delicately sweet and decadent sashimi.

Eating lunch at the Keyakidaira Station food court, we tried the glass shrimp curry. The shrimp lent the curry a lighter and more refreshing feeling than any hearty meat would have.

Firefly Squid

This variety of small squid can only be sampled in Hyogo or Toyama Prefectures, when in Japan. It can be prepared in lots of ways, including steamed, soy-pickled, stir-fried, and as sashimi. One of these dishes, firefly squid okizuke, is prepared by pickling the squid inside and out in a mix of sake and soy sauce. They say that if you try firefly squid okizuke on white rice, it’s so delicious you won’t need anything else to go with it! In addition, we recommend you try the much rarer dish of firefly squid shabu-shabu hotpot. You can find that particular entree at the ryokan we mentioned before, Unazuki Onsen Togen Ryokan.

Plan Your Unazuki Onsen Trip: Enjoy the Great Outdoors in Kurobe

Also known as “Japan’s Northern Alps”, only in Toyama Prefecture will you find the Torokko Train, where you can tour the beautiful natural scenery of the gorge. It’s a place fun to travel with friends or family, a place where you’ll find views so beautiful that you never get tired of looking, delicious food made from local agricultural specialties, and dynamic activities.

If all this made you think you’d also like to enjoy Toyama to the fullest, why not try a trip to Kurobe’s Unazuki Onsen?
