Starting at the Shiobara Onsen Visitor Center
The western starting point is the Shiobara Onsen Visitor Center, located near the entrance to Maeyama National Forest. Before setting out, visitors can stop at the center to learn about the area’s natural environment and check information about the walking trails.
From the Visitor Center, follow the path through the forest. At the T-junction, turn left and continue for approximately 200 meters before reaching the road along National Route 400. Turn right and proceed toward Fukuwata Bridge.
The surrounding woodland includes Japanese beech and Japanese oak, along with other trees that provide habitats for many wild birds. The forest offers a pleasant introduction to the natural environment of Shiobara before the trail descends toward the river.
Fukuwata Bridge and Tengu Rock
Crossing Fukuwata Bridge brings visitors to a scenic stretch of the Hoki River gorge. The bridge is an excellent place to look toward Tengu Rock, a striking rock formation rising above the river.
After crossing the bridge, turn right and follow the riverside path. This section brings the sound and scenery of the flowing water close to the walking route. The combination of rock faces, forest, and clear water makes it one of the enjoyable sections of the course.
Fukuwata Fudo Suspension Bridge
One of the main highlights is Fukuwata Fudo Suspension Bridge, which is approximately 34 meters long. It is one of the 14 suspension bridges in the Shiobara area and provides a memorable crossing over the river.
After crossing the bridge, the trail changes direction to the left and continues through the wooded valley. From the bridge, visitors can look down toward the river and appreciate the rugged landscape that has been shaped by flowing water over time.
Open-Air Hot Springs: Iwanoyu and Fudonoyu
The area around Fukuwata Fudo Suspension Bridge is also known for its rustic outdoor hot springs, including Iwanoyu and Fudonoyu. Surrounded by rocks and trees, these baths offer an atmospheric way to experience Shiobara’s hot spring culture in a natural setting.
The riverside environment gives this part of the trail a distinctive character. Visitors who wish to enjoy the hot springs should check current access arrangements and bathing conditions before their visit.
Kinta-iwa Garden and the Yashio Azaleas
As the route continues through the woodland, visitors reach Kinta-iwa Garden, an area known for its natural vegetation and seasonal flowers. Large Japanese red pine trees grow here, adding to the character of the forest.
The course takes its name from yashio azaleas, particularly the akayashio variety, which bloom in abundance around mid-April. Their delicate pink flowers brighten the forest and gorge, creating one of the area’s most attractive spring scenes.
Japanese beech and Japanese oak are among the characteristic trees of the surrounding woodland. The forest also provides habitats for numerous wild birds, making this a pleasant place for nature observation throughout the year.
Nuno Falls: A Waterfall Like a Hanging Cloth
After passing the camping area, the trail reaches the observation deck for Nuno Falls. The waterfall takes its name from the appearance of the water as it flows through a narrow opening between rocks. The white cascade resembles a length of cloth hanging down from the boulders.
The observation deck is an excellent place to view the waterfall at close range. The contrast between the white water, dark rock surfaces, and surrounding greenery makes it a particularly appealing spot for photography.
Hoki River Dam: The Eastern End of the Course
The trail continues beyond the Nuno Falls observation area and ends at Hoki River Dam. The dam is surrounded by woodland, where visitors can enjoy the quiet atmosphere of the valley.
A narrow footbridge crosses the river near the eastern trailhead. This provides a distinctive final view of the water and the surrounding landscape before completing the walk.
Seasonal Scenery Along the Yashio Course
Spring is one of the most popular times to walk the course. Around mid-April, the akayashio azaleas bloom, adding soft pink color to the forest. Other spring wildflowers can also be found along the trail.
In summer, the trees provide shade and the sound of the Hoki River creates a refreshing atmosphere. Autumn brings changing foliage to the gorge and woodland, while winter offers a quieter view of the valley.
Because the route combines forest paths, riverside scenery, bridges, and waterfalls, the experience changes as visitors move through the landscape. It is a rewarding walk for anyone interested in the natural beauty of Shiobara.
