8 Beautiful Onsen in the Japanese Alps (Winter & Summer)

Northern Japanese Alps Onsen - Hakuba Yari Onsen Goya

In Japan, you can visit thousands of great hot springs, but one of the most rewarding onsen experiences is the soak in a remote mountain hot spring in the Japanese Alps after a long hike. I have already written a post about beautiful hot springs in the mountains, but I also wanted to write one just about beautiful onsens in the Japanese Alps.

If you are looking for onsen deep in the Japanese Alps Hakuba Yari Onsen Goya in Nagano and Takamagahara Onsen in Toyama are your best choices. Mikurigaike Onsen is Japan’s highest onsen, while Hakuba Highland Hotel and Renge Onsen Rotenburo are more accessible hot springs in the Japanese Alps.

Below you will find a good mix of secret onsen and more accessible onsen located in the Japanese Alps. Since Japan’s Alps stretch over several Prefectures and are divided into the Northern Alps (Hida Mountains), the Central Alps (Kiso Mountains), and the Southern Alps (Akaishi Mountains), I tried to find beautiful onsen in each mountain range, but most of my recommendations are located in Japan’s Northern Alps. Some of the onsens are only accessible in summer, but others you can also visit in the winter months.

1. Hakuba Highland Hotel (Northern Alps)

Northern Japanese Alps Onsen - Hakuba Highland Hotel

Location: Hakuba, Near Nagano & Matsumoto, Nagano Prefecture

General Information: Hakuba Highland Hotel (白馬 ハイランド ホテル) is an onsen hotel located in the renowned winter ski resort Hakuba Happo-One Snow Resort. The resort is near Mount Shirouma, one of the major peaks in the Hida Mountain range of Japan’s Northern Alps and the 26th tallest mountain in Japan. For many Japanese hikers, the mountain is extremely high on their to-climb list. It is one of the few peaks that have snowfields all year round and if you descend via the slopes of Yarigatake you can soak or stay at Hakuba Yari Onsen, one of the highest natural onsen in Japan.

Onsen near the Northern Alps: The hotel’s gender-separated onsen facilities feature an indoor bath, a 10-meter wide open-air bath, and a private onsen bath with beautiful views of the Japanese Alps. Since the hotel welcomes day-trippers you can soak in the hot spring located at a height of 700 meters above sea level even as a non-staying guest. You can come here all year round and soak from 11:00 – 20:00 o’clock. In winter you will be surrounded by snow while in autumn you can see colorful fall colors.

Private Onsen: If you are staying overnight you can also rent the private onsen. The rental fee is 3,000円 (about $30 or 25€) and you can soak for 50 minutes.

Access: From the nearest JR station, Hakuba Station, the hotel is a 15-minute walk away. From Nagano, you can get there in 90 minutes if you take the bus. Matsumoto is a 1-hour train ride away.

Price: 700円 (about $7 or 6€), but each month on the 26th it is only 400円

General Information: Hakuba Yari Onsen Goya (白馬 鑓 温泉 小屋) aka Hakuba Yari Onsen Hut is a natural onsen right in the middle of the Hakuba Yarigatake mountain range in the Northern Alps. The only way to get there is a 5-hour climb all the way up to 2,100 meters above sea level. While the hike isn’t too dangerous or too steep and can be done by beginners, you definitely need to be prepared and can’t head out without proper hiking gear.

Onsen in the Northern Alps: Hakuba Yari Onsen is a natural sulfur hot spring with superb views of the Hida Mountains. At an elevation of 2,100 meters above sea level, it is one of the highest onsens in all of Japan. The hot spring facilities feature an Ashiyu, a women-only indoor bath, and a unisex outdoor bath. From 20:00 – 21:00 the open-air bath is exclusively for women, though, and men can use the indoor bath instead. I am not the only one who thinks that this onsen is one of the coolest in all of Japan, right?

Season: The best season for hiking is from late-July to mid-September. In 2020, the hut might open later than usual because of the renovation work of the hot spring. You will find the exact dates on their webpage.

Access: 5-hour hike from Sarukura, one of Hakuba’s climbing trail entrances, and the summit of Mount Shriouma. Sarukaru is a 30-minute bus drive from Hakuba. For safety reasons, you should arrive at the mountain hut before 4 pm.

Price: 500円 (about $5 or 5€). Staying overnight at the hut will cost 7,500円 (about $68 or 60€) per person without meals or up to 11,000円 (about $100 or 89€) per person with dinner and breakfast. When you check-in you can also order a lunch box for the next day for an additional 1,300円 (about $12 or 11€).

5. Takamagahara Onsen (Northern Alps)

Northern Japanese Alps Hot Spring - Takamagahara Onsen

Location: Deep in Japan’s Northern Alps, Toyama Prefecture

It is nestled deep in the mountains and can only be reached if you embark on a 4-day hiking round-trip through the Chubu Sangaku National Park and Japan’s Northern Alps. Be warned that this is not a hike you should choose to do as a beginner. Besides strength and stamina, you also need to be able to read and forecast the mountain weather. But if you get to the onsen, you will be rewarded with a small milky blue hot spring bath.

Onsen deep in the Northern Alps: The onsen has covered baths for each gender and a mixed outdoor bath. As you can see this onsen does not offer the most luxurious onsen experience, but I am sure that is exactly what you are looking for, right? Surrounded by only rocks, alpine trees, the sound of nature, and a few yellow plastic buckets, you can dip into the natural open-air hot spring bath 2,100 meters above sea level and revitalize for the intense 2-day hike back to the civilization.

Season: Hiking is possible from somewhen in July to late October. The opening dates of the mountain huts differ each year depending on the weather.

Central Japanese Alps Onsen - Komakusa No Yu Hot Spring

Location: Hayataro Onsen, Near Matsumoto, Nagano Prefecture

General Information: Komakusa No Yu Hot Spring  (こまくさ の 湯) is a local hot spring spa at the foot of Japan’s Central Alps. It is really close to the Kiso Moutain Range and the Komagatake Ropeway that will bring you right up to Senjojiki Cirque – one of the most scenic spots in the Central Alps. If you want to get to the summit of Mt. Kiso-Komagatake, the highest peak in the Kiso Mountain Range, it will take you about 2 hours from the cirque. There is also a 1-hour trail around the cirque with beautiful views of Japan’s Central Alps. It is also possible to hike up to the cirque, but it will take 6 – 8 hours.

Onsen near the Central Alps: Komakusa No Yu is a hot spring day spa and one of the 10 onsens of the Hayataro Hot Spring Village.

Bathing is possible from 10:00 – 21:00 o’clock, except for the 2nd and 4th Wednesday of a month. If you are looking for an onsen to stay overnight I would recommend Nagomi No Yuyado Nakayama. They have really nice cypress baths.

Hey. I'm Alex. I've been living in Japan since 2015. Before moving to Tokyo, I traveled through Japan for 7 months to visit all 47 prefectures. Traveling and staying in Japan has been so much fun and such an incredible experience that I decided to write about it. I noticed there isn't a lot of information about hot springs and onsen towns in Japan, so I'm focusing on this topic. Hopefully, my articles will help you to get the most out of your trip and to fully enjoy your time in Japan! Alex
