A Thrilling Walk Above the Reservoir
The greatest attraction of Zao Bridge is its exhilarating design. The bridge has a steel-grid floor, allowing visitors to look directly down toward the surface of the Futakawa Dam reservoir as they walk across.
Looking through the gaps beneath your feet gives you a strong sense of the bridge’s height, creating an exciting experience for visitors who enjoy a little adventure. Although the bridge was once open to small vehicles, it is now reserved for pedestrians, allowing visitors to cross at a leisurely pace and enjoy the scenery.
From the middle of the bridge, the calm water below contrasts beautifully with the surrounding mountains. The combination of the bright red structure, blue-green reservoir, and rugged natural landscape also makes this an excellent location for photography.
Beautiful Scenery Throughout the Seasons
The landscape around Zao Bridge changes dramatically with the seasons. In spring, approximately 1,000 Yoshino cherry trees bloom along about four kilometers of the Futakawa Dam reservoir. The combination of pink cherry blossoms and the red suspension bridge creates a particularly beautiful scene.
In the season of fresh green foliage, the mountains become covered in brilliant shades of green. During summer, the surrounding forests and gentle mountain breeze provide a refreshing atmosphere.
In autumn, the mountains are transformed by colorful foliage, creating a spectacular backdrop for the bridge and reservoir. In winter, the landscape becomes quieter and more serene, offering a different kind of beauty.
Because of these seasonal changes, Zao Bridge is worth visiting at different times of the year. Each season provides a unique perspective on the relationship between the bridge, reservoir, and surrounding mountains.
Futakawa Dam and the Aridagawa River
Futakawa Dam, crossed by Zao Bridge, is an important facility built for flood control and hydroelectric power generation on the Aridagawa River.
The Aridagawa River originates near Mount Yohryuzan in the Koya Mountains and flows for approximately 94 kilometers through Wakayama Prefecture. The river has historically caused flooding in the surrounding region, making effective water management an important part of protecting communities downstream.
Construction of Futakawa Dam began in 1963, and the dam was completed approximately four years later in 1967. During periods of heavy rainfall, the reservoir stores water and regulates the amount released downstream, helping to reduce the risk of flooding.
The stored water is also used for hydroelectric power generation, contributing to the supply of renewable energy. The dam therefore plays an important role not only in disaster prevention but also in supporting the region’s energy infrastructure.
The Vast Futakawa Dam Reservoir
The Futakawa Dam reservoir covers approximately 0.86 square kilometers. Its broad expanse of water creates an impressive landscape surrounded by mountains.
The reservoir is also an important water resource supporting local communities and industries. On calm days, the surface of the lake reflects the surrounding mountains, creating a peaceful landscape that contrasts with the thrilling experience of crossing the suspension bridge.
A Scenic Destination for a Road Trip
Zao Bridge is approximately 40 minutes by car from Arida Interchange. It can be reached using local prefectural and national roads, making it a convenient destination for visitors exploring the inland areas of Wakayama by car.
It is also possible to reach the area by bus from JR Fujinami Station. The journey through the countryside offers beautiful views of mountains, forests, rivers, and rural communities along the way.
