Otari Village, located in Kitaazumi District in northwestern Nagano Prefecture, is a beautiful mountain village known for its spectacular natural environment and exceptionally heavy snowfall. In winter, the village is transformed into a vast landscape of snow, attracting skiers and snowboarders from Japan and around the world. From spring through autumn, the scenery changes dramatically, offering opportunities for hiking, trekking, hot-spring bathing, nature exploration, and discovering the history of the old mountain roads.
With its rugged mountains, clear rivers, alpine wetlands, traditional villages, and historic routes, Otari offers a quieter side of the Japanese Alps. It is an ideal destination for travelers who want to experience Japan’s mountain culture and pristine nature away from major urban centers.
Otari Village lies at the northwestern edge of Nagano Prefecture, with the Himekawa River flowing through its central valley. The eastern part of the village extends into the Myoko-Togakushi Renzan National Park, where mountains of the Kubiki Range rise to around 2,000 meters. Among them is Mount Amakazari, standing at 1,963 meters and recognized as one of Japan’s famous 100 mountains.
To the west lies the Chubu-Sangaku National Park, where the mountains of the Hakuba Range rise to around 2,500 meters. Few villages in Japan are associated with two national parks in such a concentrated area, making Otari an exceptional destination for mountain and nature enthusiasts.
The village is also located along the Itoigawa-Shizuoka Tectonic Line, one of Japan’s major active geological fault zones. Its steep terrain and complex geology have historically contributed to landslides and mountain slope collapses. Today, extensive disaster-prevention measures and engineering works can also be seen as part of the region’s relationship with its mountainous environment.
Approximately 88 percent of Otari’s total area is covered by forest, while cultivated land accounts for less than three percent. The extensive forests have been recognized as a Forest Therapy Base, offering visitors an environment where they can slow down and reconnect with nature. Tsugaike Kogen, one of the village’s best-known mountain resort areas, is another symbol of Otari’s spectacular natural setting.
Otari is surrounded by mountains that provide excellent opportunities for hiking, trekking, photography, and alpine sightseeing. The landscape changes with altitude and season, from lush forests and mountain streams to alpine plants and snow-covered peaks.
Mount Hakuba-Norikura is known for its alpine vegetation in summer and winter sports in the snowy season. The changing landscape makes it an attractive destination throughout the year.
Mount Tengu is a scenic mountain area suitable for nature walks and photography. Nearby, Mount Amakazari rises to 1,963.2 meters on the border between Nagano and Niigata prefectures. Its distinctive twin-peaked summit is often called the “Cat’s Ears”. On clear days, hikers can enjoy views extending toward the Sea of Japan.
Mount Korenge stands on the Nagano-Niigata prefectural border and forms part of the magnificent Northern Alps landscape. Mount Hieda, meanwhile, is remembered for the major Hiedayama landslide of 1911, an important event in the geological and disaster-prevention history of the area.
The Himekawa River and its tributaries, including the Matsukawa, Nakanigawa, and Kusukawa rivers, provide Otari with abundant water resources. The village’s rivers and mountain streams contribute to the rich forests and agricultural landscapes found throughout the valley.
The Urakawa Super Underground Sabo Dam is particularly notable as Japan’s first large-scale underground-channel-type erosion-control dam. It demonstrates how the local community has developed innovative ways to manage the powerful natural forces of the surrounding mountains.
Otari is also home to beautiful mountain lakes and ponds such as Hakuba-Oike Pond, Kazafu-ike Pond, and Kamaike Pond. Each takes on a different character with the seasons, from fresh green foliage in spring and summer to brilliant autumn colors reflected on the water.
Tsugaike Nature Park is one of Otari’s most spectacular natural attractions. Located inside Chubu-Sangaku National Park at an elevation of approximately 1,900 meters, the park contains extensive high-altitude wetlands surrounded by the mountains of the Northern Alps.
Wooden boardwalks make it possible to explore the wetlands while minimizing the impact on the fragile alpine environment. During summer, hundreds of species of alpine plants bloom across the landscape, creating a colorful contrast with the rugged mountains.
The journey itself is part of the experience. The Tsugaike Gondola and Ropeway provide an aerial route toward the park, allowing visitors to watch the forests and mountain slopes change as they climb higher.
Located near Tsugaike Nature Park at an elevation of around 1,900 meters, the Tsugaike Visitor Center introduces visitors to the area’s alpine plants, wildlife, and natural environment. Exhibits, quizzes, a rope-climbing activity, and live cameras provide an accessible way for visitors of different ages to learn about the mountain ecosystem before exploring the park.
The Tsugaike Gondola and Ropeway form a mountain transportation route with a total length of approximately 5,320 meters. The journey combines the gondola lift “Eve” with the Tsugaike Ropeway, carrying visitors toward Tsugaike Nature Park while offering expansive views over the forests and Northern Alps.
Mount Amakazari is one of the most distinctive peaks in the Otari area. Rising to 1,963.2 meters, it straddles the border between Nagano and Niigata prefectures and is one of Japan’s celebrated 100 mountains.
The mountain’s twin summit resembles the ears of a cat, giving rise to its charming nickname, “Cat’s Ears.” The summit provides dramatic views of the surrounding mountains and, when weather conditions are favorable, the distant Sea of Japan.
Amakazari Kogen Campground is located within Myoko-Togakushi Renzan National Park and serves as a base for climbing Mount Amakazari. The campground offers 42 auto-camping sites, making it suitable for travelers exploring the mountains by car.
Visitors can enjoy outdoor activities such as barbecues and campfires, as well as the distinctive experience of bathing in a drum-can bath surrounded by nature.
Kamaike Pond lies at an elevation of approximately 1,190 meters and is surrounded by an impressive beech forest. A walking trail of about 2 kilometers circles the pond, making it an accessible destination for enjoying the forest scenery.
In spring and early summer, fresh green leaves surround the clear water, while autumn brings brilliant foliage. The reflections of the surrounding forest and mountains on the surface of the pond create some of Otari’s most photogenic seasonal landscapes.
Otari is one of Japan’s designated Special Heavy Snowfall Areas, and its abundant winter snowfall is one of the defining features of the village. The deep snow creates ideal conditions for skiing and snowboarding while transforming the mountain landscape into a spectacular winter wonderland.
Tsugaike Mountain Resort is one of the best-known ski areas in the village and attracts skiers and snowboarders from Japan and overseas. Its broad mountain terrain and abundant snowfall make it a major winter destination in the Hakuba area.
Hakuba Norikura Onsen Ski Resort offers terrain suitable for a wide range of skiers, from beginners to experienced riders. Its location near hot-spring facilities also makes it possible to combine a day on the slopes with a relaxing bath.
Hakuba Cortina International Ski Resort is particularly well known for its abundant snowfall and high-quality powder snow. The resort’s deep winter snow attracts powder enthusiasts looking for an authentic Japanese mountain experience.
Together, these three ski resorts form a major part of Otari’s winter tourism industry and have helped establish the village as an internationally recognized snow destination.
Otari is home to several hot-spring areas, providing an ideal way to relax after hiking, skiing, or exploring the surrounding mountains. Otari Onsen and Himekawa Onsen are among the best known, while Shimosarise Onsen and Kuruma Onsen offer additional opportunities to enjoy traditional Japanese bathing culture.
The combination of snow-covered mountains, outdoor activities, and natural hot springs is one of the defining attractions of a stay in Otari.
Michi-no-Eki Otari is located along the historic Chikuni Kaido road and introduces visitors to local foods and products from the village. Travelers can enjoy dishes prepared with local ingredients, including Otari-grown Koshihikari rice cooked in a traditional wood-fired hearth.
The roadside station also features Miyama no Yu, a natural hot spring with water supplied directly from the source, making it a convenient place to combine local cuisine with a relaxing bath.
Otari has played an important role in the history of transportation through the Japanese Alps. During the medieval period, the area formed part of Chikuni-no-sho, a medieval estate, and later became an important stopping point on the Chikuni Kaido, also known as the Salt Road.
The route connected Matsumoto with Itoigawa and was used to transport salt and seafood from the Sea of Japan toward inland regions. Merchants, pack-animal handlers, travelers, and local residents all moved along this demanding mountain route, making it an important economic and cultural link between inland Shinshu and the coast.
During the Edo period, Chikuni Post Town developed as one of the important stations along the Salt Road. The Chikuni Guard Station, operated by the Matsumoto Domain, was established here to control and monitor traffic along the route.
Today, historical facilities and reconstructed buildings allow visitors to imagine what life was like when the Salt Road was an important artery of trade.
Ushikata-juku is a historic building designated as a Nagano Prefectural Treasure and is the only surviving former pack-animal handlers’ inn along the Chikuni Kaido. The late-Edo-period building features a traditional thatched hipped roof.
Pack-animal handlers who transported salt and seafood through the mountains once stayed here with their animals. The building offers a rare glimpse into the practical realities of travel and trade in the Japanese Alps during the Edo period.
Chikuni-no-Sho Historical Museum recreates the site of a former checkpoint on the Salt Road. Traditional houses have been relocated and preserved, together with facilities associated with the old checkpoint and salt storage.
Exhibits introduce the people, trade, transportation, and everyday life connected with the Salt Road, helping visitors understand why this remote mountain valley once played such an important role in regional commerce.
One of the most rewarding ways to experience Otari’s history is to walk sections of the old Salt Road. The routes combine mountain scenery with stone monuments, historic sites, traditional villages, and cultural facilities.
The Chikuni Pass Salt Road Trail is a model walking route of approximately 9 kilometers between Tsugaike Kogen and the central Otari area. Along the way, travelers encounter stone Buddhist images, historic sites, local museums, and traditional mountain landscapes.
The route offers more than a hike through nature. It is an opportunity to follow the footsteps of people who once carried salt and seafood across the mountains and to experience the close relationship between transportation, commerce, and village life.
Chikuni Suwa Shrine stands quietly among the mountain settlements along the Salt Road. The shrine is known for its distinctive traditional festival featuring a performance called “Sasara-suri.”
Performers known as “Sasara-shi” wear unusual masks, including masks resembling the humorous face of a hyottoko, and perform distinctive movements as part of the local ritual tradition.
Along the Maeyama section of the Salt Road, more than 80 stone Kannon statues are gathered together at a historic site. The collection brings together statues representing the Saigoku, Chichibu, and Bando pilgrimage routes, creating a remarkable concentration of Buddhist stone images in the mountain landscape.
A statue of Kobo Daishi dating from 1858 also remains here, adding another layer of historical interest to this quiet roadside site.
Otari’s mountain communities preserve a variety of traditional festivals and local events that reflect the village’s history and close relationship with nature.
The Salt Road Festival invites participants to walk along sections of the historic Chikuni Kaido. Dressed in traditional-style clothing and accompanied by local cultural activities, the event brings the history of the old trade route to life.
The Hana Toro Festival is a summer event in which beautiful lanterns create a dreamlike atmosphere after dark. The soft lights add a magical dimension to Otari’s traditional mountain scenery.
Yuki to Hi no Matsuri, the Snow and Fire Festival, celebrates winter in Otari with the dramatic contrast of snow and fire. It is one of the village’s distinctive seasonal traditions and offers visitors a chance to experience local winter culture.
Held in autumn, the Otari Shin-Soba Festival celebrates freshly harvested local buckwheat. For travelers interested in Japanese regional cuisine, it is an excellent opportunity to enjoy soba while experiencing the atmosphere of a mountain community.
Spring brings melting snow, fresh greenery, and the return of mountain trails. Streams swell with snowmelt, while the forests gradually turn from winter white to vivid green.
Summer is the season for hiking, alpine flowers, trekking, camping, and exploring Tsugaike Nature Park. The cool mountain climate provides a refreshing escape from the heat of the cities.
Autumn transforms the beech forests and mountain slopes into brilliant shades of red, orange, and yellow. Kamaike Pond is particularly beautiful at this time of year, with the colorful forest reflected on its calm surface.
Winter covers Otari in deep snow and brings the village’s famous ski resorts to life. The combination of abundant powder snow, mountain scenery, and hot springs makes the season especially appealing to winter travelers.
Otari Village brings together many of the experiences that define the mountain regions of Japan: dramatic peaks, deep forests, alpine wetlands, clear rivers, traditional hot springs, historic roads, rural culture, and world-class winter sports.
From the alpine landscapes of Tsugaike Nature Park and the dramatic summit of Mount Amakazari to the historic Chikuni Kaido Salt Road, the village offers opportunities to experience both the natural and cultural heritage of the Japanese Alps.
Whether you visit for powder snow and skiing, summer mountain trekking, colorful autumn forests, traditional festivals, or a relaxing hot spring stay, Otari offers a deeply immersive mountain experience.
