Warm, Mineral-Rich Hot Spring Waters
The waters of Kamibayashi Onsen include sodium-calcium chloride springs and sulfate springs. The source temperature is approximately 68°C, making the spring naturally hot.
These mineral-rich waters have traditionally been valued for their warming and therapeutic qualities. They are associated with relief from conditions such as neuralgia, muscle pain, joint pain, sensitivity to cold, and chronic skin disorders, and the hot spring has also been used as a destination for toji, the traditional Japanese practice of extended hot spring bathing for rest and recuperation.
After bathing, the skin may feel pleasantly smooth and moisturized, while the warmth of the water helps create a deeply relaxing experience in the mountain environment.
Jigokudani Monkey Park
One of the most famous attractions near Kamibayashi Onsen is Jigokudani Monkey Park, located approximately 30 minutes on foot from the hot spring area.
The park is internationally known for its wild Japanese macaques, which can be seen soaking in natural hot springs, particularly during the snowy winter months. Watching wild monkeys relax in steaming thermal water while snow covers the surrounding mountains has become one of the most distinctive winter scenes in Japan.
For overseas visitors, the combination of a traditional mountain hot spring and the unique wildlife of Jigokudani makes Kamibayashi an especially interesting base for exploring northern Nagano.
Kamibayashi Fudoson
At the far end of the hot spring settlement stands Kamibayashi Fudoson, a sacred site associated with mountain religious traditions.
A traditional fire-walking ritual known as Sendayaki is held here by practitioners of Shugendo, a Japanese tradition of mountain asceticism. Participants walk across hot embers as part of a religious ceremony.
The surrounding atmosphere offers a glimpse of the area’s long connection with mountain worship. Away from the main tourist routes, this quiet sacred space provides an opportunity to experience a different aspect of Japanese spiritual culture.
Connections with the Nagano Winter Olympics
Next to the hot spring area was formerly the Kamibayashi Ski and Snowboard Park, where the snowboard halfpipe competition was held during the 1998 Nagano Winter Olympics. The facility is no longer in operation, but the wider Shiga Kogen region remains one of Japan’s major winter sports destinations.
During the snowy season, skiers and snowboarders gather throughout the surrounding mountains. The area’s abundant snowfall, high elevation, and extensive ski terrain have made Shiga Kogen internationally known as a winter resort.
Shrines, Temples, and Cultural Attractions
At the lower end of the hot spring settlement stands Amakawa Shrine, a local place of worship with a long history. Onbashira, sacred wooden pillars associated with traditional shrine festivals in Nagano, are erected on the shrine grounds, and powerful portable shrine processions can be seen during festival periods.
The surrounding area also contains museums, galleries, and folk-culture facilities. These places offer visitors opportunities to explore the region’s artistic traditions and local history alongside its hot spring culture.
Senjukaku: A Classic Japanese-Western Hotel
Kamibayashi Hotel Senjukaku
Kamibayashi Hotel Senjukaku is a prestigious long-established hot spring hotel built in the early Showa period by the Nagano Electric Railway group.
The hotel’s architecture combines Japanese and Western design, creating an elegant atmosphere that reflects the history of modern tourism in Nagano. Spacious guest rooms and facilities including a heated swimming pool provide a comfortable setting for a longer stay.
Surrounded by the natural beauty of the mountains, the hotel offers a chance to enjoy the changing scenery of Shiga Kogen while experiencing the refined atmosphere of a historic mountain resort.
The Beginning of Kamibayashi Onsen
The history of Kamibayashi Onsen as a modern resort dates back to 1902, when Kobayashi Tamisaku, a wealthy landowner from Sarashina, in what is now Nakano City, developed the area as a private villa and hot spring retreat.
The development of the area soon became closely connected with the history of tourism and skiing in Shiga Kogen.
The Beginning of Ski Culture in Shiga Kogen
In 1913, a German couple staying in the area enjoyed skiing here. Their visit is regarded as an early milestone in the development of skiing culture in Shiga Kogen.
What began as an unusual mountain activity gradually developed into a major winter tourism tradition, eventually helping transform the surrounding highlands into one of Japan’s best-known ski destinations.
Tohei Kozu and the Development of the Resort
In 1928, Tohei Kozu, the founder of Nagano Electric Railway, established a hot spring hotel in Kamibayashi.
The following year, Lieutenant Olaf Helset, coach of the Norwegian Olympic team at the St. Moritz Winter Olympics, visited the area. He reportedly praised the landscape as the “St. Moritz of the Orient.”
This recognition helped accelerate tourism development in Shiga Kogen and contributed to the region’s growing reputation as a mountain resort with international potential.
A Retreat for Famous Figures
Kamibayashi Onsen attracted many prominent visitors over the decades, including members of the Japanese imperial family, military figures, writers, politicians, and other cultural figures.
Among those associated with the area were the future Emperor Showa, who visited while still Crown Prince, Puyi, the last emperor of China’s Qing dynasty, and Prince Takamatsu.
Kobayashi Tamisaku actively invited writers and artists to stay in the area, helping Kamibayashi develop a reputation not only as a place for hot spring relaxation but also as a retreat for literature and the arts.
