Hayataki Falls is a powerful waterfall located near the foot of Mount Akakunawa, in the upper reaches of the Shiozawa River in Kanna Town, Tano District, Gunma Prefecture. With a drop of approximately 30 to 40 meters, it is a plunging waterfall known for its abundant flow and impressive spray.
The clear waters eventually flow into the Kanna River, and the waterfall is regarded as one of the most scenic natural attractions in Kanna Town. Its appearance changes dramatically with the seasons, from fresh green forests in spring and summer to colorful foliage in autumn and a spectacular wall of ice in winter.
Hayataki Falls is located at an elevation of approximately 900 meters, where winter temperatures can become extremely cold. The waterfall usually begins to freeze gradually around the end of December, reaching its most impressive state around February.
When temperatures remain low enough, much of the waterfall becomes encased in ice, creating a magnificent frozen waterfall and a gigantic work of art created entirely by nature.
When the waterfall freezes almost completely, the sight is particularly spectacular. It is also known as a rare destination for viewing an icefall in the wider Kanto region. During the coldest part of winter, experienced ice-climbing enthusiasts may be seen climbing the frozen waterfall, although specialized equipment, experience, and careful safety measures are essential.
From spring through summer, the surrounding forest becomes covered in vivid fresh greenery, while the area around the waterfall remains cool and refreshing. Even during the hottest part of summer, the mountain environment provides a pleasant escape from the heat.
In autumn, deciduous trees such as konara oak, maple, and pine change color, creating a striking contrast between the brilliant foliage and the white stream of the waterfall. At higher elevations, visitors can also see Japanese larch, mizunara oak, and Japanese white birch, with the entire mountain landscape gradually taking on the colors of autumn.
The geology around Hayataki Falls consists of a Jurassic mélange matrix, part of an accretionary complex formed through complex geological processes. White siliceous rocks as well as green and red metamorphic rocks are intricately mixed together.
As a result, colorful rocks can be seen along the riverbed, adding distinctive shades and textures to the scenery around the waterfall. Hayataki Falls is therefore a place where visitors can appreciate both the beauty of nature and the geological history of the region.
Hayataki Falls cannot be reached by public transportation. Visitors must travel by car and then continue on foot. From the direction of Kanna Town, take National Route 462, turn right at the corner near Hachiman Shrine, and follow the Shiozawa River upstream.
After passing Shiozawa Dam, the road climbs a steep slope, and it is possible to drive along the forest road to a point partway up the mountain.
From there, the route becomes a hiking trail. The trail includes sections with fixed chains, loose rocky ground, and steep slopes alongside cliffs. Shortly before reaching the waterfall, hikers must also pass a smaller waterfall, where the footing can be unstable.
Careful preparation is especially important in winter, when the road and trail may be covered with snow or ice. Visitors should also remain alert for wildlife such as bears, Japanese mamushi pit vipers, and hornets. Appropriate clothing, footwear, equipment, and knowledge of mountain safety are essential.
Hayataki Falls is one of the “Seven Waterfalls of Kanna”, a collection of waterfalls scattered throughout Kanna Town. A visit to these waterfalls allows travelers to experience the changing character of the mountains throughout the year—from the sound of flowing water and fresh green leaves to colorful autumn foliage and snowy winter landscapes.
Because visitors can walk around to the back of the waterfall, Irisawa Falls is also known as “Ura no Taki,” or the Backside Waterfall. A statue of Fudō Myōō is enshrined here, and the waterfall has long been associated with local religious traditions.
With a drop of approximately 30 meters, Fudō Falls was named after the Fudō Myōō figure enshrined among the rocks. The contrast between the powerful flow of water and the rugged rock face creates an impressive scene.
Located approximately 10 minutes on foot from the Nanakubo-Hashikura Forest Road, Azuki Falls is relatively accessible, allowing visitors to approach the area near the base of the waterfall. The colorful rock formations harmonize beautifully with the surrounding woodland.
Shiramizu Falls is an elegant waterfall where water flows like fine white threads over a limestone rock face. Its delicate appearance reflects the natural landscape shaped over an immense span of time.
A walking path and parking area are available near Kujū Falls, making it one of the easier waterfalls in the area to visit. The falls can also be viewed from a distance from Watado Bridge.
Located along the Manmozawa River near National Route 299, Ōse Falls quietly appears between the surrounding trees. Its secluded setting makes it a peaceful place to enjoy the natural atmosphere of the mountains.
Hayataki Falls combines a powerful flow, an impressive 30- to 40-meter drop, and the extraordinary scenery of a frozen waterfall in the depths of winter. Each season offers a different experience, making it one of Kanna Town’s most distinctive natural attractions.
Exploring Hayataki Falls together with the other waterfalls of Kanna provides a deeper appreciation of the area’s forests, streams, geology, and seasonal landscapes. Because the route involves challenging terrain, visitors should prioritize safety and come properly prepared before setting out to experience this remarkable mountain waterfall.
