A Volcanic Landscape with Remarkable Rock Formations
One of the most fascinating features of Jofu Falls is the contrast between its red and black volcanic rock and the vivid green moss growing across the cliff.
This unusual landscape was created by volcanic activity associated with Kusatsu-Shirane Mountain. The vertically striated rock formations have characteristics resembling gentle columnar joints and are composed of welded tuff formed from volcanic ash and pyroclastic flows known as the Shirane Pumice Flow.
Relatively young lava layers known as Moto-Shirane Lava can also be found above the waterfall. Long-term erosion has carved hollows into the rock, while some sections have developed icicle-like formations resembling stalactites.
These geological features make Jofu Falls more than a scenic waterfall. The cliffs themselves provide a fascinating glimpse into the volcanic history of the Kusatsu region.
The Powerful 70-Meter Cascade
Water plunges approximately 70 meters down the enormous rock face, creating an impressive sight as the stream cuts through the rugged volcanic landscape.
Although the pool at the bottom of the waterfall is not particularly large, the area in front of the falls opens up widely, allowing visitors to appreciate the full scale and force of the cascade.
During the season of fresh green foliage and again in autumn, the scenery becomes especially beautiful. The colors of the volcanic rock, moss, waterfall, and surrounding trees combine to create a landscape that resembles a traditional Japanese painting.
Beautiful Scenery Throughout the Seasons
Jofu Falls is particularly attractive from spring through autumn.
In spring and early summer, fresh green leaves surround the white cascade, creating a refreshing mountain scene. In autumn, the surrounding forests turn brilliant shades of red and yellow, contrasting dramatically with the dark and reddish volcanic cliffs.
The waterfall is therefore a popular destination for visitors interested in nature photography and scenic hiking.
The surrounding area is also home to alpine plants and fossil-bearing areas, making it an interesting place for observing the region’s natural environment.
Jofu Falls can also be viewed from a section of the natural trail connecting Yoshigadaira with Kusatsu Onsen, making it a popular scenic destination for hikers exploring the mountains.
Views from the Nature Trail and Observatory
Jofu Falls is located along the natural walking route between Yoshigadaira and Kusatsu Onsen. Today, visitors generally enjoy the waterfall from a viewing platform overlooking the falls from a distance.
From the observatory, the waterfall blends beautifully into the surrounding mountain landscape. The composition of the white water, colored rock, forests, and distant mountains creates a tranquil scene reminiscent of a traditional Japanese landscape painting.
The hiking route leading directly to the base of the waterfall is currently closed because of the risk of falling rocks. Visitors cannot therefore walk all the way to the foot of the falls.
Before visiting, be sure to check the latest safety information and enjoy the waterfall from the designated viewing area.
Jofu Falls Bottom Hot Spring — A Hidden Natural Spring
Along the former hiking route is a small unnamed waterfall, and below it is a natural hot spring informally known as Jofu Falls Bottom Hot Spring.
This type of naturally occurring outdoor spring is known in Japan as a noyu, or “wild hot spring.” In the past, the secluded spring was known among adventurous visitors as a hidden hot spring deep in nature.
Today, access is difficult because of safety concerns and restrictions. Nevertheless, the spring remains an interesting example of the close relationship between the area’s volcanic activity and its abundant hot spring resources.
A small pocket park was also developed at the former site of Washinoyu below the waterfall. The project received a 1993 Handmade Hometown Award in recognition of its harmonious integration with the local natural environment.
Access to Jofu Falls
By Car
Jofu Falls is approximately five minutes by car from Kusatsu Onsen. From the hot spring town, follow National Route 292 toward Kusatsu Onsen Ski Resort.
After traveling approximately 1.7 kilometers from the Kusatsu intersection toward Mount Shirane, turn onto a forest road on the right.
The forest road may be inaccessible at times because of falling rocks and other hazards. Visitors should check the latest road conditions before attempting to drive farther.
Parking at Kusatsu Onsen Ski Resort or the Tenguyama No. 6 parking area is a convenient option.
Walking to the Viewing Platform
From an area near a hairpin bend, it takes approximately 15 minutes on foot along the forest road to reach the Jofu Falls viewing platform.
From the Tenguyama parking area in the hot spring town, the walk takes approximately 50 minutes.
The route passes through a natural mountain environment, so visitors should wear comfortable, sturdy walking shoes and prepare appropriately for outdoor conditions. Because the area is surrounded by wilderness, travelers should also take appropriate precautions regarding encounters with wild animals, including bears.
A Spectacular Waterfall Shaped by Nature
Jofu Falls offers a completely different experience from the lively streets and hot spring baths of Kusatsu Onsen. Here, visitors can encounter the powerful beauty of the natural landscape that surrounds the resort.
The unusual volcanic cliffs, approximately 70-meter waterfall, vivid moss, and changing colors of the surrounding forest reveal the immense forces that have shaped the Kusatsu mountains over thousands of years.
For travelers interested in waterfalls, geology, hiking, photography, and natural landscapes, Jofu Falls is a fascinating destination near Kusatsu Onsen.
When visiting, check current access and safety information in advance and enjoy the magnificent scenery from the designated viewing area. Combined with a visit to Kusatsu Onsen, Jofu Falls provides an opportunity to discover the deeper connection between volcanic activity, mountain landscapes, and the hot springs of Kusatsu.
