Teruha Suspension Bridge is a dramatic pedestrian suspension bridge in Aya Town, Higashimorokata District, Miyazaki Prefecture. Spanning the Honjo River, also known in this area as the Ayaminami River, the bridge offers sweeping views of a deep valley surrounded by the lush evergreen broadleaf forests of southern Kyushu.
The bridge is one of Aya’s signature attractions and an excellent destination for travelers who want to experience the scale and beauty of Japan’s mountain forests. From the elevated walkway, visitors can look across the forest canopy, admire the steep valley walls, and enjoy a distinctive view of the natural landscape from above.
Teruha Suspension Bridge also received the Excellence Award in the Civil Engineering Design Prize 2004, recognizing its design and contribution to the landscape.
The bridge was constructed after the surrounding evergreen broadleaf forest area was designated part of the Kyushu Central Mountains Quasi-National Park on March 28, 1984. It was designed as a steel suspension bridge exclusively for pedestrians, providing a way for visitors to experience the forest and gorge without disturbing the surrounding landscape with road traffic.
The original bridge measured 250 meters in length and stood approximately 142 meters above the valley. At the time, it was regarded as the second-highest pedestrian suspension bridge in Japan. Stone monuments near the bridge carry inscriptions referring to the bridge’s distinction as a world-class walking suspension bridge and to the outstanding natural environment of the evergreen broadleaf forest.
Bridge type: A steel, long-span, two-hinged stiffening suspension bridge.
Completion: March 28, 1984.
Total length: 250.0 meters.
Height above the valley: 142.0 meters.
Walkway width: 1.2 meters.
Main tower height: 28.0 meters.
Main cables: Four cables, each with a diameter of 50.0 millimeters.
These specifications help explain the bridge’s impressive appearance. Its long span carries visitors high above the valley, while its relatively narrow pedestrian walkway creates a close connection with the surrounding landscape.
In October 2010, reconstruction work began because of the deterioration of the original bridge. The project had a total budget of approximately 320 million yen and was initially scheduled for completion in March 2011.
However, the work was extended to include replacement of the main towers. The reconstructed bridge reopened on October 5, 2011.
One notable feature of the renewed structure is that sections of the walking surface use open mesh flooring. These sections allow visitors to look down through the walkway toward the valley below, adding an extra sense of height and excitement to the crossing.
For visitors who enjoy dramatic viewpoints, this design creates an especially memorable experience. At the same time, people who are uncomfortable with heights may prefer to proceed slowly and concentrate on the surrounding forest scenery rather than looking directly down through the floor.
Teruha Suspension Bridge crosses the Honjo River, which forms part of the Oyodo River system. The wider river basin extends through Kobayashi City, Aya Town, Kunitomi Town, and Miyazaki City in Miyazaki Prefecture.
The upper reaches of the river are characterized by abundant vegetation and a relatively unspoiled mountain environment. The evergreen broadleaf forests surrounding the bridge form part of the protected natural landscape of the Kyushu Central Mountains Quasi-National Park.
The river, steep valleys, and extensive forest cover create a landscape in which water and vegetation are closely connected. Visitors can appreciate the way the forest follows the contours of the mountains and blankets the slopes around the gorge.
The forests around Teruha Suspension Bridge are among the area’s most important natural features. Extensive evergreen broadleaf woodland stretches across the mountains, including areas around the Ayakita River.
These forests have been recognized for their importance to Japan’s natural heritage. The source notes that the Aya evergreen broadleaf forest has been selected for both the 100 Best Waters and the 100 Best Forests for Water Sources, while the evergreen forest of Aya Gorge has been included in a selection of Japan’s natural environments worth preserving for the 21st century.
The forest is important not only for its scenery but also for its role in protecting water resources. Vegetation helps retain water in the landscape, supports the surrounding ecosystem, and contributes to the supply of water flowing into the area’s rivers.
Numerous springs are found throughout the forested landscape. Their waters flow into the Honjo River and Ayakita River, connecting the mountain forest with the river systems below.
In 1985, these springs were selected as one of Japan’s 100 Remarkable Waters under the name Aya River Spring Group. This recognition highlights the quality and importance of the area’s water resources.
For visitors, the springs and rivers add another dimension to the forest landscape. The environment can be appreciated as an interconnected system in which forests, groundwater, springs, and rivers all contribute to the character of the region.
The Honjo River was once used as a transportation route for goods moving through the region. Until approximately the 1920s, during the Taisho period, sailing boats were able to travel upstream as far as Aya Town.
Goods were transported along the river and passed through landing places known as kamba in Aya and Kunitomi. From there, they were carried toward Akae Port at the mouth of the Oyodo River, where cargo could be transferred to larger coastal vessels known as sengokubune for shipment toward the commercial centers of western Japan.
During the Edo period, Honjo in Kunitomi was particularly important because it was part of territory under the direct control of the shogunate. The movement of rice and other goods through the area had an influence on rice prices across the former province of Hyuga.
This history reveals a different aspect of the river. Today, visitors mainly associate it with forest scenery and recreation, but it once played a practical role in connecting inland communities with regional and national trading networks.
Crossing Teruha Suspension Bridge is the central experience for most visitors. The elevated walkway provides an unusual viewpoint from which to appreciate the depth of the valley and the extent of the surrounding evergreen forest.
As you walk across, take time to observe the different layers of the landscape: the nearby trees, the steep slopes descending into the gorge, and the broader forest extending across the mountains. The open sections of the walkway provide a particularly direct view into the valley below.
The scenery changes with the seasons. The evergreen forest maintains much of its foliage throughout the year, while changes in light, weather, and the surrounding vegetation create different moods. Clear conditions offer especially wide views, while mist and clouds can give the forested gorge a more atmospheric appearance.
The area around the bridge is suitable for visitors who enjoy nature walks and forest scenery. Spending time in the surrounding environment allows travelers to appreciate the forest beyond the viewpoint offered by the bridge itself.
The natural landscape is particularly appealing to photographers and visitors interested in ecology, mountain environments, and the conservation of native forests. The bridge also provides a useful introduction to Aya’s wider natural attractions, including the evergreen broadleaf forest that has become central to the town’s identity.
Visitors should follow designated routes and respect any local safety instructions. Weather conditions can affect visibility and the experience of crossing a high suspension bridge, so it is worth checking conditions before setting out.
The source identifies Minami-Miyazaki Station on the JR Nippo Main Line as the nearest railway station for the described public-transport route.
From the Miyazaki Kotsu Bus Center at Miyako City, take a bus toward Aya Machiaisho, the terminal stop in Aya Town. The bus journey takes approximately one hour. From the terminal, continue by taxi for around 15 minutes to reach Teruha Suspension Bridge.
Because bus services and connections can vary, visitors should check current timetables before traveling, particularly if they intend to return to Miyazaki City on the same day.
By car, the bridge can be reached from the Takahara Interchange on the Miyazaki Expressway. The source describes a journey of approximately one hour via National Route 268 toward Miyazaki and the Aya area.
Driving provides greater flexibility for exploring the bridge together with Aya Castle, craft workshops, and other attractions in Aya Town. Actual journey times depend on road conditions, traffic, and the chosen route.
Teruha Suspension Bridge offers a rare opportunity to experience the forested mountains of Miyazaki from high above a deep valley. Its 250-meter span, elevated position, open sections of walkway, and views of the Aya evergreen broadleaf forest make it one of the region’s most distinctive scenic attractions.
The bridge also provides access to a landscape of considerable ecological and historical importance. The surrounding forests protect valuable water resources, the springs have received national recognition, and the Honjo River once served as a route for transporting goods between inland settlements and coastal ports.
For travelers exploring Aya Town, Teruha Suspension Bridge combines a dramatic outdoor experience with an introduction to the natural heritage of southern Kyushu. It is a rewarding destination for anyone who appreciates forest landscapes, mountain scenery, and the connection between nature and local history.
