A Waterfall Changed by History
According to historical accounts, a large boulder once stood at the lip of the waterfall, dividing the falling water into two streams. In 1813, when the Takada Domain transported felled timber downstream by floating it along the river, the force of the logs damaged the boulder. The rock was broken apart, leaving the single main waterfall that visitors see today.
The Origin of the Name “Naena”
Several theories have been proposed for the name Naena. One explanation is that the tremendous roar of the waterfall sounded like an earthquake. In older Japanese, the word “nawi” referred to an earthquake, and the name is thought to have gradually changed from “Nai no Taki” to “Naena Taki” and eventually “Naena Falls.”
Another tradition connects the name with agriculture. The water from the Seki River supplies rice fields in the Takada Plain downstream, and the waterfall’s name may have developed in association with the cultivation of rice seedlings.
A Spectacular Geological Landscape
Magnificent Basalt Columnar Joints
One of Naena Falls’ most striking features is the impressive columnar jointing visible in the basalt around the waterfall. The dramatic vertical rock formations were created by volcanic activity associated with Mt. Kurohime, where andesite lava flowed into and blocked the Seki River.
The angular columns of rock rise on both sides of the waterfall, creating a powerful natural frame for the falling water. For visitors interested in geology, these formations offer an opportunity to see the effects of ancient volcanic activity directly in the landscape.
Layered Lava Formations Along the Trail
Other interesting geological formations can be seen along the walking trail. In places, the lava appears to consist of many thin layers stacked on top of one another, known as platy joints.
Together with the columnar joints around the falls, these formations make Naena Falls more than a scenic viewpoint. It is also a fascinating place to observe the geological history of the northern Nagano and Myoko region.
Four Waterfalls Hidden within the Gorge
Although Naena Falls is generally regarded as a single waterfall, the gorge actually contains four successive waterfalls. The first waterfall is the main one visible to ordinary visitors, while the second, third, and fourth falls are much more difficult to reach.
Because access to these upper sections is challenging, most visitors experience Naena Falls from the main viewpoint. Even so, the dramatic gorge and powerful flow create an unforgettable impression.
Four Seasons of Mountain Scenery
The landscape around Naena Falls changes beautifully throughout the year. Spring brings fresh green foliage and abundant snowmelt, summer offers cool mountain air, autumn surrounds the gorge with brilliant colors, and winter transforms the landscape into a snowy scene.
The waterfall is particularly impressive in spring, when melting snow dramatically increases the volume of water. Autumn is another especially popular season, as red, orange, and yellow foliage contrasts beautifully with the white water cascading through the gorge.
Naena Falls in Japanese Culture and Local Life
Painted by a 19th-Century Literati Artist
Naena Falls became known as a subject of artistic appreciation during the 19th century. The literati painter Toyo Etsuchinjin created numerous works depicting the waterfall, helping spread awareness of its striking beauty.
A Natural Calendar for Rice Farming
For generations, the natural landscape around the waterfall has also been closely connected with agriculture. On Mt. Myoko, a distinctive snow formation known as the “Cow-Shaped Snow Pattern” appears as snow melts from the mountain slopes.
Together with the changing flow of Naena Falls, this natural phenomenon was traditionally used as a seasonal signal for the beginning of rice planting. When the snow melted in spring and the waterfall began flowing with greater force, local farmers would begin preparing their fields.
This tradition reflects a way of life in which people closely observed the rhythms of the mountains, snow, rivers, and fields.
Walking to the Waterfall
A Scenic Trail and Suspension Bridge
A walking trail leads from the parking area toward the waterfall. The walk to the observation point near the base of the falls takes approximately 15 minutes.
Along the way, visitors cross a suspension bridge, adding a touch of adventure to the journey. As the bridge sways gently beneath your feet, the increasingly powerful sound of the waterfall builds anticipation before the falls finally come into view.
Feel the Power of the Water Up Close
From the observation area, Naena Falls can be viewed from close range. The spray from the waterfall may reach visitors, allowing them to experience the force of the water not only visually but also through sound and sensation.
The combination of roaring water, towering cliffs, forest, and spray creates an immersive encounter with the natural power of the Japanese mountains.
The Best Seasons to Visit
Spring Snowmelt and Autumn Foliage
Spring and autumn are particularly rewarding times to visit Naena Falls. During the spring snowmelt season, water from the surrounding mountains swells the Seki River, making the waterfall even more powerful.
In autumn, the surrounding mountains become covered in brilliant foliage. The contrast between colorful leaves and the rushing white water creates one of the area’s most memorable landscapes.
A Cool Summer Escape
Naena Falls is also popular during summer as a refreshing escape from the heat. The forested surroundings provide shade and cool air, making the trail suitable for a relaxing nature walk.
Visitors can enjoy the sound of the river, the scent of the forest, and the songs of birds while exploring the area.
A Forest Therapy Destination
Naena Falls serves as one end of the Myoko Kogen Nature Trail, which is also recognized as a forest therapy route. Walking through the surrounding woodland offers a chance to slow down and reconnect with nature.
The sound of flowing water, the fragrance of trees, and birdsong create a peaceful atmosphere that makes the area particularly appealing to travelers seeking relaxation and a break from busy city life.
How to Reach Naena Falls
By Public Transportation
The waterfall is located approximately 8 kilometers west of Myokokogen Station on the Echigo Tokimeki Railway Myoko Haneuma Line.
From the station, visitors can use the Myoko City-operated “Buratto Myoko Sanroku” sightseeing loop bus. A transfer is required at Myoko Kogen Hot Spring Village.
During certain seasons, the Myoko Kogen Liner operated by Keinan Bus also provides a direct connection from Joetsu-Myoko Station on the Hokuriku Shinkansen.
By Car
By car, take the Myoko Kogen Interchange on the Joshinetsu Expressway and follow Niigata Prefectural Route 39, the Myoko Kogen Park Line, toward Sasagamine. After approximately 4 kilometers, turn left at the Naena Falls entrance and continue for approximately 2 kilometers.
A parking area is available near the trailhead, making Naena Falls relatively convenient to visit by car.
Experience the Power of Naena Falls
Naena Falls combines dramatic scenery, volcanic geology, local history, traditional agriculture, and the changing beauty of the seasons. Its 55-meter drop and thunderous roar are impressive enough on their own, but the surrounding landscape reveals an even deeper story.
From the columnar basalt formed by ancient volcanic activity to the snowmelt that once served as a natural signal for rice planting, the waterfall demonstrates how closely nature and human life have been connected in this mountain region.
A Spectacular Stop in the Myoko and Shinano Area
Whether you visit during the powerful spring snowmelt, the cool green summer, or the colorful autumn foliage, Naena Falls offers a memorable encounter with the natural landscape of northern Japan.
Listen to the thunderous roar, walk across the suspension bridge, admire the extraordinary volcanic rock formations, and feel the cool spray of the falls. A visit to Naena Falls is an opportunity to experience the beauty and power of the Japanese mountains at close range.
