A Magnificent Gorge with Eight Waterfalls
Yaedaki is the collective name for a series of waterfalls flowing through the gorge of the Tamiya River, a tributary of the Mitoya River system.
Starting downstream and continuing upstream, the eight waterfalls are Sarutobi Falls, Takijiri Falls, Momiji Falls, Kajika Falls, Uba Falls, Hime Falls, Yashio Falls, and Yashio Falls.
Each waterfall has its own distinctive character. Some are powerful and dramatic, while others flow gently between rocks and trees. Together, they create a constantly changing landscape along the gorge.
The Main Falls: Yashio Falls and Yashio Falls
A Powerful Two-Tiered Waterfall
The most impressive section of Yaedaki is found at the upper end of the gorge, where Yashio Falls and Yashio Falls form a two-tiered waterfall with a combined drop of approximately 40 meters.
The upper section is called Yashio Falls, while the lower section is called Yashio Falls. Viewed together, the two sections form one large and powerful waterfall.
When the water level is high, the abundant flow creates a particularly spectacular sight as the water rushes down the rocky gorge.
Walking Through the Waterfall Gorge
A Forest Trail Along the Mountain Stream
One of the best ways to experience Yaedaki is by walking along the maintained trail that follows the stream.
From the parking area to the furthest waterfalls, the trail is approximately 1,100 meters long and takes around 35 to 40 minutes on foot, depending on walking pace and trail conditions.
Along the way, the trail crosses bridges and rocky sections and passes through lush forest. The sound of flowing water accompanies visitors throughout much of the walk, creating a relaxing atmosphere.
Beautiful Scenery in Every Season
The landscape changes throughout the year. In spring and early summer, fresh green leaves bring bright colors to the forest. In autumn, the surrounding trees turn shades of red, orange, and yellow, creating a spectacular contrast with the clear stream and dark rocks.
The quiet atmosphere of the forest also makes Yaedaki an enjoyable destination for travelers who want to experience a more peaceful side of rural Japan.
A Rich Natural Environment
More Than 200 Species of Plants
The Yaedaki area is rich in biodiversity, with more than 200 species of plants recorded in the surrounding gorge.
Trees such as Ubamegashi oak, Japanese camellia, and Japanese dogwood grow throughout the forest. The damp environment also supports many species of mosses and ferns.
As you walk along the trail, it is possible to observe the subtle differences in vegetation created by the rocks, water, shade, and changing seasons.
A Habitat for Wildlife
The surrounding mountains are home to a variety of wildlife, including wild boar, Japanese raccoon dogs, and foxes. Birds such as the Brown Dipper and Japanese wagtail can also be found around the clear mountain streams.
The area is also inhabited by the Japanese giant salamander, which is designated as a Special Natural Monument of Japan. The presence of such wildlife reflects the rich and relatively undisturbed natural environment of the gorge.
A Place Where History and Belief Remain Alive
Yaeyama Shrine and Local Legends
The area around Yaedaki is connected not only with nature but also with local history and religious traditions.
Nearby Yaeyama Shrine has long been an important place of worship for local residents. Local mythology tells of Susanoo-no-Mikoto, a major deity in Japanese mythology, defeating a supernatural enemy in this region.
These legends add a mysterious cultural dimension to the surrounding forests and waterfalls, allowing visitors to experience a landscape shaped by both nature and traditional beliefs.
Yaedaki Festival
Every year on August 14, the Yaedaki Festival is held in the area.
The festival includes a traditional ceremony praying for safety, along with sales of local specialty products and various community events. Held amid the natural surroundings of the waterfall gorge, the festival provides an opportunity to experience the connection between the local community, nature, and traditional culture.
Safety Tips for Visitors
Because Yaedaki is located in a natural mountain environment, visitors should prepare appropriately before setting out on the trail.
Be aware of bears. The surrounding area is a bear habitat, so carrying a bear bell or another item that makes noise is recommended.
Travel with other people whenever possible. Hiking with companions is preferable to walking alone in the mountain environment.
Wear sturdy, non-slip footwear. Parts of the trail follow natural terrain, and some areas may be uneven, wet, or slippery.
Take your time on rocky sections and bridges, especially after rain or when the ground is wet. Staying alert to trail conditions will help you enjoy the waterfall walk safely.
Yaedaki and Ryuzugataki Waterfall
Two of Unnan’s Great Waterfall Destinations
Yaedaki and Ryuzugataki Waterfall, located approximately 10 kilometers to the north, are both part of the Ryuzugataki-Yaedaki Prefectural Natural Park.
Ryuzugataki is known for its impressive 40-meter-high Male Waterfall and 30-meter-high Female Waterfall. One of its most unusual attractions is the opportunity to view the waterfall from behind the falling water, a feature known in Japan as a “back-view waterfall.”
Both Yaedaki and Ryuzugataki have been selected as Japan’s 100 Best Waterfalls, making them important natural attractions in Unnan City.
Although they are located in separate areas, visiting both waterfalls allows travelers to experience two distinctly different types of waterfall scenery. Yaedaki offers a series of waterfalls connected by a forest trail, while Ryuzugataki features dramatic larger falls and a rare view from behind the water.
A Peaceful Journey Through Nature
Yaedaki Waterfalls is an excellent destination for travelers who want to experience the beauty of Japan’s forests and mountain streams.
The eight waterfalls create a constantly changing landscape along the approximately 1.5-kilometer gorge, while the maintained walking trail makes it possible to explore the area on foot.
Clear water, lush vegetation, wildlife, and the quiet atmosphere of the forest make the journey as enjoyable as the waterfalls themselves. Each season brings a different appearance, from fresh green foliage in spring to colorful autumn leaves.
The nearby Yaeyama Shrine and local legends also reveal another side of the area, where traditional beliefs and stories have been passed down alongside the natural landscape.
For those with enough time, combining Yaedaki with Ryuzugataki creates an especially rewarding waterfall excursion in Unnan City. With appropriate footwear and attention to natural trail conditions and wildlife, visitors can enjoy a refreshing walk through one of Shimane’s beautiful mountain landscapes.
