The Origin of the Name “Nishina”
The origin of the place name “Nishina” is not certain, but one widely discussed theory connects the two characters used in the name with the area’s landscape. The character “ni” is thought to refer to reddish-brown loam soil, while “shina” may refer to slopes or stepped terrain.
Many place names containing the character “shina” were found in the northern part of the ancient Shinano region, suggesting that the name may have originally described the area’s distinctive topography.
The name initially referred to the area around Nishina Shinmeigu Shrine, a shrine associated with the worship of Ise Grand Shrine. As the influence of the powerful Nishina clan, who served as local officials, expanded during later periods, the name came to refer more broadly to the surrounding region.
Lake Aoki: Crystal-Clear Water and Alpine Scenery
Lake Aoki is the northernmost and largest of the Three Lakes of Nishina. Its exceptionally clear water is one of its defining characteristics, with abundant spring water believed to emerge from the lake floor.
The lake sits at an elevation of approximately 822 meters, covers about 1.7 square kilometers, and reaches a maximum depth of approximately 58 meters. Its transparency can reach around 9.8 meters, making it one of the clearest lakes in Nagano Prefecture.
From the lakeshore, visitors can admire the Hakuba mountain range and other peaks of the Northern Alps. The scenery changes dramatically throughout the year, from cherry blossoms in spring and lush greenery in summer to brilliant autumn foliage and snowy winter landscapes.
Outdoor Activities on Lake Aoki
In summer, Lake Aoki becomes a popular destination for camping, canoeing, and stand-up paddleboarding. The peaceful surface of the lake is especially beautiful in the early morning, when the surrounding mountains can be reflected like a mirror.
Visitors can also enjoy a cycling route around the lake. In early summer, special cruises may offer the opportunity to see fireflies glowing around the lakeshore, creating an enchanting nighttime experience.
Lake Kizaki: A Friendly Lakeside Recreation Area
Lake Kizaki is the southernmost of the Three Lakes of Nishina. Compared with the other two lakes, it has a wider range of tourism facilities and is particularly well suited to visitors looking for recreational activities.
Because parts of the lake are relatively shallow and the water is comparatively warm, Lake Kizaki becomes lively during summer. Visitors can enjoy water-based recreation and swimming while the surrounding mountains and forests provide a beautiful natural backdrop.
Hot springs, cafés, campsites, and accommodation are located around the lakeshore, making Lake Kizaki popular with families and groups. Fishing is also an important attraction, with anglers coming to catch species such as herabuna and smelt.
Seasonal Beauty of Lake Kizaki
From late spring into early summer, water lilies bloom across the lake, creating an atmospheric scene on the water. In autumn, colorful foliage is reflected on the lake surface, adding another layer of beauty to the surrounding landscape.
Lake Nakatsuna: A Quiet Lake of Reflections
Lake Nakatsuna is the smallest of the Three Lakes of Nishina. Its smaller scale contributes to its particularly peaceful atmosphere, making it an appealing destination for travelers who want to enjoy the lakes and mountains away from busy tourist areas.
The lake is known for its clear water and is especially popular among fishing enthusiasts. Herabuna fishing attracts repeat visitors and anglers from around Japan, while the calm environment makes fishing a relaxing experience.
Seasonal Highlights at Lake Nakatsuna
In spring, Oyamazakura wild cherry trees bloom along the shore, with their pink flowers reflected on the water. This picturesque combination has made the lake a favorite photography location.
Summer is ideal for enjoying the lake’s greenery and outdoor activities, while autumn brings colorful foliage reflected in the calm water. In winter, the lake can freeze over, allowing ice fishing for smelt when conditions permit.
The Nōgu River Connects the Three Lakes
The three lakes are linked by the Nōgu River. Beginning at Lake Aoki, the river flows through Lake Nakatsuna and then into Lake Kizaki before eventually joining the Takase River.
This interconnected water system is an important part of the region’s natural geography. As the river passes through the lakes, sediment settles and the water is naturally moderated, helping to maintain relatively stable water flow even during periods of rainfall.
The Nōgu River also plays an important role in local agriculture. Its water is used for irrigation, supporting farmland extending from Omachi City toward Ikeda Town.
Water levels can also be regulated at the Lake Kizaki water gate, allowing the river and lakes to contribute to the agricultural and everyday needs of the surrounding communities.
A Destination for Four-Season Outdoor Recreation
The Three Lakes of Nishina offer activities throughout the year. Camping, fishing, canoeing, SUP, cycling, and lakeside walks are popular during the warmer months, while winter brings opportunities for snow sports and, under suitable conditions, ice-based activities.
The area is also a rewarding destination for photography. Reflections of the Northern Alps, cherry blossoms, autumn foliage, mist, snow, and changing skies create dramatically different scenes depending on the season and time of day.
Because the three lakes are relatively close together, travelers can easily visit more than one in a single trip and experience their different atmospheres.
Protecting the Natural Environment
The natural beauty of the Three Lakes of Nishina depends on the quality of their water and surrounding ecosystems. In recent years, concerns about water pollution and other environmental pressures have highlighted the importance of enjoying the lakes while respecting and protecting their natural environment.
For visitors, simple practices such as taking all waste home, avoiding unnecessary disturbance of wildlife, and following local rules for fishing and outdoor recreation help preserve these landscapes for future generations.
Discover the Different Personalities of the Three Lakes
The Three Lakes of Nishina share the same mountain setting, but each offers a distinctive experience.
Lake Aoki is the place to admire exceptionally clear water, dramatic Northern Alps scenery, and outdoor adventures such as SUP, canoeing, camping, and cycling.
Lake Nakatsuna offers a quieter atmosphere, beautiful reflections, cherry blossoms, and a long-standing fishing culture. It is particularly appealing to travelers looking for peaceful scenery and a slower pace.
Lake Kizaki has a more recreational character, with campsites, hot springs, cafés, water activities, and fishing facilities that make it especially accessible for families and groups.
A Lakeside Journey Through the Northern Alps
The Three Lakes of Nishina form one of the most distinctive natural landscapes in the Omachi area. Their waters, connected by the Nōgu River, reflect the surrounding mountains and forests while supporting local agriculture, recreation, and wildlife.
Spring cherry blossoms, cool summer waters, autumn colors, winter snow, fishing, camping, canoeing, SUP, cycling, and even firefly viewing offer different ways to experience the region throughout the year.
For travelers exploring the Northern Alps, visiting all three lakes provides a chance to experience several sides of Shinshu nature in one journey. From the crystal-clear waters of Lake Aoki to the quiet reflections of Lake Nakatsuna and the lively recreational atmosphere of Lake Kizaki, the Three Lakes of Nishina offer a memorable combination of mountain scenery, outdoor adventure, and peaceful lakeside landscapes.
