Surrounded by mountains, Matsumoto City has a wealth of hot spring sources. Among them, Shirahone Onsen (白骨温泉) tops the list with its picturesque natural scenery and cultural elements. Putting its somewhat scary name aside, you will surely be enchanted by the onsen town’s charm!
Shirahone Onsen is located at the foot of the northern Japanese Alps. With Kamikōchi at its north and Norikura Kōgen just a 20-minute drive away, the onsen town is well-known to the Japanese, but not many foreign travelers are aware of its existence.
The milky hot spring has a weak acidity that is gentle to your skin. Drinking the hot spring has many health benefits as well, including better blood circulation to the digestive system and relieving constipation.

Where Did the Onsen Town Get its Scary Name from?
If you read some Japanese/Chinese characters, you might be scared off when you see the onsen resort’s name because “白骨” can literally mean white bones. How it got its horrifying name has something to do with the minerals in the hot spring.
The onsen at Shirahone is initially transparent. However, because it contains hydrogen sulfide and calcium, it turns cloudy when the spring comes into contact with the air.
The hot spring source was discovered in the Kamakura period (1192 – 1333). As time passed, people started seeing white lime crystalized on the surface of the wooden boat placed above the hot spring. So the region was named Shirafune (白船), meaning white boat.
Somehow, before you realize it, Shirafune becomes Shirabone…(´▽｀*)
Hot Spring Fountain and Hot Spring Porridge (温泉粥)
Consuming a slight amount of white sulfur and carbonic acid can improve blood flow in the digestive organs. This means your organs will function better, and thus, it is effective in relieving constipation.
In Shirahone Onsen, two onsen fountains are installed for public use to make it more convenient for everyone to obtain the hot spring to drink. Furthermore, at many ryokans and restaurants, you can taste Shirahone Onsen’s specialty, the hot spring porridge (Onsen-gayu, 温泉粥)!
Apparently, the rotten egg smell of the sulfur-based onsen will disappear after the hot spring is cooked!
If you stay overnight at Shirahone Onsen, the ryokan will most likely serve you Onsen-gayu for breakfast (=ﾟωﾟ)ﾉ.
Shirahone Onsen Sanjūsan Kannon (白骨温泉三十三観音)
The first attraction closest to the Shirahone Onsen bus stop is the 33 Kannon Bodhisattva statues.
Just steps away in the large car park to the right of the bus stop, the statues made in the Edo period (1603 – 1867) are placed opposite the public toilets. They were offered by the guests who had benefited from the hot spring’s medical property to show their appreciation.
In the past, when medical resources were limited, most Japanese relied on hot springs to cure wounds and recover from illness. It was said that if you indulge in the hot spring for three days in a row, you won’t catch a cold for the next three years!
Ryūjin Falls (竜神の滝)
Ryūjin means ‘a dragon god’ in Japanese. So you might be expecting something really magnificent. But betraying your expectations, the word ‘elegant’ is probably more suitable to describe this waterfall.
Just a 2-minute walk from Shirahone Onsen Sanjūsan Kannon, Ryūjin Falls flows smoothly over the moss-covered limestone slope next to the prefectural road. Consisting of strings of water falling across the wide rock surface, the waterfall is a spiritual spot where the dragon god who looks after the water lives.
While you might not find the 20-meter tall waterfall impressive, if you include the limestone caverns on the rock surface and the greenery that the water flows over, it is a gorgeous picture that nature has painted for us.
Apart from the early spring’s fresh green and the vivid fall, the best time to adore Ryūjin Falls is between January and February, when it becomes an icefall.
Again, different from our stereotype, the frozen Ryūjin Falls look more like stalagmites in limestone caves than a large ice curtain. If you walk directly below it, you might worry that those sharp icicles will drop on you…
Tsuitooshi Tunnel and Kansuikei Valley (隧通し・冠水渓)
Walking further down for around 5 minutes from Ryūjin Falls, One of the spots in Shirahone Onsen that almost all tourists will visit is the natural wonder, Tsuitooshi Tunnel, and Kansuikei Valley.
Due to the continuous erosion by the Yu River (湯川), a tunnel was formed at the bottom of a limestone cliff. The mountain stream that flows out of the 6 meters tall and 20 meters long tunnel is named Kansuikei. Standing at the bridge above the river, watching the dynamic water flow out of the tunnel, you will feel the mighty power of nature!
From the closest car park/Shirahone Onsen stop, the narrow promenade is built along the Kansuikei River. You might not realize it, but the bus stop where you came from is actually just at the top of the tunnel!
Important: The earthen road is slippery, especially after rain. It is best to trek on it with a pair of sneakers. Also, be aware the observatory is aging.
How to Get to Tsuitooshi Tunnel and Kansuikei Valley
The trailhead is located around 100 meters away from the bus stop, Shirahone Onsen (白骨温泉) or Shirahone Onsen Tourist Center (白骨温泉ご案内処). Facing the bus stop/Tourist Center, you need to follow the road at your right (prefectural road).
Hot Spring Spout Mounds and Spherical Limestones (Funtōkyū・Kyūjō Sekkaiseki, 噴湯丘・球状石灰岩)
今日から北アルプスの線状凹地を掘る調査。リーダーのT先生以下、メンバーが松本集結。まずは白骨温泉の噴湯丘や石灰華を見学。凹凸のある地形で崩壊地形と紛らわしい。 pic.twitter.com/4hcMsnzkBi

The hidden attraction in Shirahone Onsen is the Water Spout Mounds and Spherical Limestones on one side of the road. If no signs are placed next to it, most people will walk straight past this Special National Natural Monument.
Because Shirahone’s hot spring contains rich calcium carbonate, a hill-like terrain is gradually formed as the precipitation of lime calcium carbonate continues. In the area, there are more than 100 such special terrains.
Although non of the hot spring spouts in Shirahone are active anymore, something unique to the town is the shape of such accumulates. Instead of a hill shape, the sediment close to Sirafuneso Grand Hotel (白船グランドホテル) is in the shape of a sphere with diameters from millimeters to four or five centimeters.
As a side note, it is said that the hot spring spouts in Shirahone Onsen were formed around 350 million years ago.
Although not marked on Google Maps, another place where you can see the special phenomenon is at the back of Ryokan Maruei (かつらの湯丸永旅館).
If you are interested, check with the ryokan staff.
Yakushi-dō (薬師堂)
On the ground of Shirahone Onsen Yumopto Saitō Ryokan (白骨温泉 湯元齋藤旅館), the small but gorgeous Yakushi-dō enshrines the Healing Buddha. Erected in 1702, the Buddha has been worshiped by visitors who came to Shirahone Onsen for the medical benefits of the hot spring. Nowadays, many tourists also come here to pray for health-related matters.
Tip: The doors of Yakushi-dō are normally closed. If you want to see the Healing Buddha, come on the 8th of June.
How to Get to Shirahone Yakushi-dō
Yakushi-dō and Shirahone Onsen Yumopto Saitō Ryokan are located at the far end of Shirahone Onsen. In front of the ryokan, there is a small hill. The worship hall is just at the top of 20 staircases.
From Shirahone Visitor Center, it is around a 15-minute walk.
The Accommodations in Shirahone Onsen
If your schedule allows, spend a relaxing night at Shirahone Onsen to enjoy all the onsen town has to offer. But before you hit that “book” button, here are a few things to watch out for:
- Not all ryokans can cater to special dietary requirements. If a ryokan can entertain the request, please inform them what you can’t eat.
- Many of Shirahone Onsen’s guestrooms don’t have a shower facility and/or bathtub. If you have booked one of those rooms, you will need to utilize the communal hot spring pools.
- Most Ryokans have thin walls. If you are sensitive to noise, it might be a better idea to stay at Shirafune Grand Hotel (白船グランドホテル).
- A few ryokans/hotels provide free pick-up and drop-off services (especially in winter). Please check with the ryokan if the service is available and book it with them in advance.
Awa no Yu Ryokan (泡の湯旅館)
Although Awa no Yu is located away from the town center, it is the ryokan that represents Shirahone Onsen. In fact, the biggest onsen pool in Nagano Prefecture is found at Awa no Yu!
If you have seen the Ghibli movie Spirited Away, you will get excited when you see how the hot spring fills the pool in the photo. Yes, it looks exactly the same as what was used in the anime, where the hot spring flows from long wooden box sections!
For more information about the ryokan, refer to our Awa no Yu article!
Konashinoyu Sasaya (小梨の湯 笹屋)
For those who want to enjoy a private outdoor onsen pool, Konashinoyu Sasaya, which isn’t too far away from Awa no Yu, is the ryokan you will want to spend a night in. Although only for 30 minutes, it is the only hot spring facility in Shirahone Onsen where daytime visitors can enjoy an open-air private onsen session!
When you check in, remember to reserve your 30-minute time slot to use the ryokan’s private onsen pool. The private space is open for reservation from the time you check in to 10 pm and from 5 am to 9:30 am.
Important: Remember to slide the sign before you go in, so it says “只今入浴中の為、しばらくお待ちください”. This is to notify people that you are inside. And please slide the sign back when you come out.
Just note that the private bath isn’t in the main building but in the annex a few meters away. This means on a rainy day, you might want to bring an umbrella with you if you don’t want to dash.
Tip: Remember to check with the staff if the drinks in the fridge in the resting space are still free.
Important: If you plan to stay at Konashinoyu Sasaya during the fall foliage season, make a reservation as early as possible to avoid disappointment. The ryokan receives bookings as early as one year in advance.
Making a Day Trip to Konashinoyu Sasaya
Important: Day trip bathing is currently suspended until further notice.

How to Get to Konashinoyu Sasaya

Ryokan Maruei (かつらの湯丸永旅館)
Similar to Awa no Yu next door, Ryokan Maruei is another ryokan with a mixed-gender outdoor bath. And yes, the female guests get to hide their bodies underneath the milky hot spring before they go past the long curtain into the outdoor area.
One thing to note is Ryokan Maruei’s outdoor bath is rather small. So you might still feel awkward even with the towels and hot spring blocking the view from others.
But, the great thing about Ryokan Maruei is a relatively more friendly price tag. And paying less doesn’t mean you will receive less than top-notch hospitality. The staff here do their best to look after their guests so that many visitors become a repeater after their first stay!
Tip: Please confirm with the staff if you can still rent out a private onsen pool.
How to Get to Ryokan Maruei
Ryokan Maruei is just opposite Awa no Yu. From the bus stop, Awanoyu (泡の湯), it is around a 2-minute walk.
Tsuribashi no Yado Sansuikan Yugawasō (つり橋の宿 山水観 湯川荘)
If you want to stay in a guestroom with a river view, Tsuribashi no Yado Sansuikan Yugawasō is the ryokan you will want to book a stay with. It is the only ryokan in Shirahone Onsen situated at the side of a river.
The ryokan also has three (two in winter) open-air and one indoor private onsen pool that you can rent out. All of them are free of extra charges to ryokan guests.
Important:
☛ If you plan to utilize the private onsen pools, remember to lock the door, so others know there is someone inside.
☛ Their guestrooms don’t come with a shower facility.
☛ The ryokan might not have English-speaking staff stationed. It would be helpful to the ryokan if you can speak basic Japanese.
Tip: If you want to enjoy your dinner in your room, check with the ryokan to see if they still can accommodate this request at an extra cost.
How to Get to Tsuribashi no Yado Sansuikan Yugawasō

Shirafunesō Shintaku Ryokan (白船荘新宅旅館)
Shirafunesō Shintaku Ryokan is one of the older ryokans in Shirahone Onsen. Opened in 1865, the ryokan’s public hot spring pool is made of Japanese cypress.
Located on high ground, the ryokan is surrounded by a forest, home to many wildlife, such as squirrels. Another rather unique thing about Shirafunesō Shintaku Ryokan is its dinner. Instead of rice, the staple food is soba noodles, which Nagano Prefecture is famous for.
Moreover, Shirafunesō Shintaku Ryokan is another hot spring facility where you can rent out one of their private onsen pools. When you check in, let the staff know you want to book the family bath Konashi (こなし). This is because Konashi has two small pools, one indoor and one outdoor. The other family pool Sumomo (すもも), only has an indoor pool.
Important: They currently cannot accommodate special dietary requirements.
