Nagano Onsen in Madarao Kogen
The Madarao Onsen, nestled in Madao Kogen in the northern Nagano mountains, provide a number relaxing hot spring options that perfectly complements the resort’s famous ski slopes.
Located across various accommodation facilities at Madarao Mountain Resort, these onsen hot springs offer the ideal way to soothe tired muscles after a day of skiing, snowboarding, or hiking. The mineral-rich waters are known for their therapeutic qualities, helping to ease fatigue, improve circulation, and provide a sense of deep relaxation. Unlike larger, busier onsen towns, the Madarao onsen have a cosy and welcoming atmosphere, with baths that let visitors unwind in a more intimate setting.
In winter, soaking in steaming hot waters while surrounded by snowy landscapes is an unforgettable experience. During summer, the Madarao onsen provides a refreshing retreat after outdoor adventures. Madarao Onsen is not just a place to bathe, but a cultural experience that connects you with Japan’s timeless tradition of hot spring bathing.

Beyond Madarao Kogen | Onsen Trips
Beyond Madarao Onsen
There are several fine public onsen in the near vicinity, although many of these require the use of a car. These include:
Madarao no Yu
At Madarao No Yu visitors can enjoy a relaxing mountain onsen located more than 1000 metres above sea level. This facility is only a five minute drive below Madarao Kogen Ski Area. There are both inside and outside baths available. Opening hours are 10 am – 8 pm. See website.
Yutaki Onsen
Yutaki Onsen is a simple alkalescent hot spring located on the banks of the Chikuma River – on Route 117 below Nozawa Onsen. This family-run establishment could quite possibly be the best bargain in the area. For only three hundred yen you get your choice of the indoor bath or magnificent rotemburo (outside onsen). The change of each season is uniquely distinct and you’ll be hard-pressed to find a better deal. Opening hours are 10 am – 9 pm (last entrance 8:30 pm). See website.
Hokuryu Onsen
Hokuryu Onsen in Iiyama City is famous as the site of the historical Kosuge Inner Shrine and also home to a forest therapy road. In the midst of this abundant natural landscape, the Bunka Hokuryukan hotel sits on the banks of the area’s heart-shaped Lake Hokuryu. From the outdoor hot spring (rotemburo), guests can look out over Northern Nagano’s spectacular five peaks of the Hokushin region and the Sekita mountain range plus enjoy views of the Chikuma River from above. The facility maintains separate bathing times for men and women. Opening hours are 11 am – 5 pm. See website.
Togari Onsen
Togari Onsen has two well known rotenburo (outside pools). Just a minute away from the Togari Onsen Ski Resort’s Orion slopes, Nozomi No Yu includes outdoor hot spring baths with a view of the gorgeous natural landscape. Akatsuki No Yu is located a short walk from the Pegasus slopes at Togari. Both of the outdoor baths are a great place to relax and enjoy views of the natural landscape. The water is said to promote beautiful skin, as well as easing muscle soreness, body aches, and stress-induced tension. During the winter, they are especially good for some post-skiing relaxation. Opening hours are 11 am – 9 pm. See website.
Maguse Onsen
Note: Sadly Maguse Onsen is closing from November 24, 2025.
Take a journey to the tiny hot springs of Maguse Onsen, perched high on the cliffs across the valley from Madarao in Kijimidaira Village. Ride up the winding roads that lead to this scenic location, then enjoy a relaxing, healing soak in one of the town’s onsen, or hot springs. At an altitude of 700 metres, you won’t find many hot spring baths in Japan so far above sea level, and few will offer the breathtaking scenery to be had at Maguse Onsen. It’s lofty location provides such an expansive view that people come from far and wide to soak in the bath while taking in the view. The indoor bath is made of hinoki (Japanese cypress) which lends a simple, natural contrast to the outdoor one which is made of cut stone. Makes an ideal after-ski expedition – great for soaking away any sore muscles. More info here.
Toyoda-mura Onsen Koen Momiji-so (phone 0269-38-3030) is situated between Kijimadaira and Madarao. It’s open 10:00 – 20:00 (closed Wednesdays). Adults are ¥500 and children ¥350.
Local town onsen scattered around the area are also available and quite inexpensive but usually consist of only one smallish bath. You will also need to bring your own toiletries and towel. Look for the the onsen symbol (as above) on maps and signs when seeking onsen.
