Nozawa Onsen is one of northern Nagano Prefecture’s most historic hot spring destinations. Located in Nozawaonsen Village in Shimotakai District, the town spreads across the lower slopes of Mount Kenashi, an old volcano rising to approximately 1,650 meters.
For centuries, people have traveled to Nozawa Onsen to enjoy its abundant natural hot springs. Today, the village retains a traditional atmosphere, with narrow streets, wooden buildings, local inns, small shops, and a unique bathing culture that continues to be part of everyday life.
One of the distinctive features of Nozawa Onsen is the remarkable variety of its natural hot springs. Source temperatures range from approximately 42°C to 90°C, and different springs have their own characteristics.
Most of the waters are sulfur-rich hot springs, traditionally appreciated for their soothing qualities and gentle effect on the skin. Among the village’s springs, Kumanote-arayu is relatively cooler, making it a more comfortable choice for visitors who are new to Japan’s hot spring bathing culture or prefer spending longer periods in the water.
Oyu is the symbolic heart of Nozawa Onsen. Its elegant traditional architecture makes it one of the most recognizable buildings in the village.
Nozawa Onsen has 13 public bathhouses, all traditionally managed by local community groups known as Yunakama. The culture of visiting several bathhouses around the village, known as sotoyu meguri, remains an important part of the Nozawa Onsen experience.
The public bathhouses are primarily intended for local residents, but visitors are welcome to use them by making a small voluntary contribution. Experiencing these community bathhouses offers an opportunity to encounter a traditional aspect of Japanese hot spring culture.
The streets of Nozawa Onsen are narrow, winding, and often steep, creating an atmosphere that feels very different from a modern resort town. Traditional inns, small restaurants, and souvenir shops line the streets around Oyu and Ogama.
Walking through the village is part of the experience. Steam rising from the hot springs, wooden buildings, stone paths, and the sounds of local life create an atmosphere that reflects the village’s long history as a hot spring destination.
The eastern slopes of the village are home to Nozawa Onsen Ski Resort, one of Japan’s major ski areas. During winter, skiers and snowboarders from Japan and overseas gather here to enjoy the area’s abundant snowfall and high-quality powder snow.
Numerous pensions and accommodations are located around the ski resort, while a large concentration of traditional guesthouses can be found closer to the hot spring town. This makes it possible to combine a full day on the slopes with a relaxing soak in a natural hot spring.
The network of 13 public bathhouses is one of Nozawa Onsen’s defining attractions. Each bathhouse has its own character, and exploring them on foot provides a memorable way to discover the village.

For visitors who prefer more modern facilities, Furusato-no-Yu is a convenient day-use hot spring facility. Compared with the traditional public bathhouses, it offers more extensive facilities and is particularly suitable for families and travelers looking for a comfortable bathing experience.
Ogama is one of Nozawa Onsen’s most distinctive sights. Extremely hot water, reaching close to 100°C, bubbles up naturally from the ground.
In the past, the heat from Ogama was used to boil hemp and remove its outer fibers. Today, the hot spring water is used by local residents for cooking vegetables, preparing hot spring eggs, and other traditional purposes.
This connection between the natural hot springs and everyday life is one of the features that makes Nozawa Onsen different from many other resort-style hot spring destinations in Japan.
Because the water is extremely hot, access to the immediate area around the springs is restricted for visitors to prevent burns and accidents. However, the site can be observed from designated surrounding areas.
Ogama provides a fascinating glimpse into how generations of local residents have made practical use of the natural heat beneath the village.
According to tradition, the hot springs of Nozawa Onsen were discovered by the Buddhist monk Gyoki during the Nara period. By the Kamakura period, Nozawa Onsen was regarded as one of the Three Great Hot Springs of Shinano, together with Nagatoro-no-yu and Shinano-no-yu.
During the Edo period, the hot springs were also used as a place for recuperation by the lords of the Iiyama domain. Over the centuries, Nozawa Onsen developed into a community where bathing, local life, and hospitality became closely connected.
Nozawana is one of the foods most closely associated with Nozawa Onsen. This traditional vegetable has long stems and leaves that are commonly preserved by pickling.
According to local tradition, the vegetable originated from seeds brought back from Kyoto by the head priest of Kempyoji Temple during the Edo period. Over time, it became deeply rooted in the local food culture.
In autumn, local residents can be seen washing freshly harvested nozawana using the hot spring water at places such as Ogama and designated washing areas near the public bathhouses. This seasonal tradition has become one of the characteristic scenes of the village.
The nearest major railway station is Iiyama Station, served by the JR East Hokuriku Shinkansen and the Iiyama Line.
From Iiyama Station, the Nozawa Onsen Liner takes approximately 25 minutes to reach the village. Local Nagaden buses also connect Iiyama Station with Nozawa Onsen, with the journey taking approximately 40 minutes.
By car, Nozawa Onsen can be reached from the Toyoda-Iiyama Interchange on the Joshin’etsu Expressway via National Route 117. The distance is approximately 20 kilometers.
From the Kan-Etsu Expressway, another route is available from the Shiozawa-Ishiuchi Interchange via National Routes 353 and 117, covering approximately 70 kilometers.
Nozawaonsen Village has a sister-city relationship with St. Anton am Arlberg in Tyrol, Austria. This international connection reflects the village’s long-standing relationship with skiing and has also contributed to cultural exchange between Japan and Austria.
Nozawa Onsen is located in a mountainous area of northern Nagano known for heavy winter snowfall. The region is particularly popular for its light, dry powder snow, attracting skiers and snowboarders from around the world.
One of the great pleasures of a winter trip here is the combination of outdoor adventure and traditional bathing culture. After spending the day skiing or snowboarding, visitors can return to the village, warm themselves in a natural hot spring, and enjoy the atmosphere of a historic Japanese onsen town.
Nozawa Onsen offers much more than a place to take a bath. Its 13 community-run public bathhouses, steaming springs, historic streets, traditional inns, local food, and surrounding mountains together create a distinctive cultural experience.
Visitors can walk from bathhouse to bathhouse, discover the traditional uses of the hot springs at Ogama, sample local nozawana pickles, and enjoy some of Japan’s finest powder snow in winter.
With its combination of centuries-old hot spring traditions, mountain scenery, skiing, and authentic village life, Nozawa Onsen is a destination where travelers can experience a deeply rooted side of Japanese culture while enjoying the beauty of Nagano throughout the seasons.
