The Role and History of Futagawa Dam
Construction of Futagawa Dam began in 1963 as part of a comprehensive flood-control project, and the dam was completed in 1967. The Arida River basin had experienced repeated severe flooding in the past, with the devastating flood of 1953 causing particularly extensive damage throughout the region.
Futagawa Dam was constructed to help protect communities downstream from such disasters. By temporarily storing water when river levels rise, the dam helps prevent a sudden increase in the amount of water flowing downstream. Water levels can also be managed according to seasonal conditions, helping reduce the risk of flooding.
A Dam That Supports Local Life
Although its primary functions are flood control and hydroelectric power generation, Futagawa Dam is also an important part of the local landscape. The reservoir created by the dam has become a scenic destination where visitors can enjoy the changing beauty of the surrounding mountains throughout the year.
Beautiful Futagawa Dam Lake
The reservoir formed by the dam, known as Futagawa Dam Lake, covers approximately 0.86 square kilometers. Its calm waters are surrounded by mountains and forests, creating a peaceful landscape that changes with the seasons.
In spring, approximately 4 kilometers of cherry trees along the lakeshore burst into bloom. The pale pink blossoms of Somei Yoshino cherry trees create a striking contrast with the blue water and fresh green mountains, making this one of the most beautiful seasons to visit.
The area is also popular as a scenic driving route. Visitors can enjoy the changing scenery of Wakayama as the landscape shifts from fresh spring greenery to lush summer forests, colorful autumn foliage, and the quiet beauty of winter.
Cross the Exciting Zao Bridge
One of the most distinctive landmarks around Futagawa Dam is Zao Bridge, a red suspension bridge stretching approximately 160 meters across the reservoir near the center of the dam area.
The bridge is now reserved for pedestrians, allowing visitors to walk across while looking down over the expansive dam lake. The experience can be surprisingly thrilling, especially for those who are sensitive to heights.
A Thrilling View from Above the Water
The floor of the bridge features a grid-like structure through which visitors can see the water below. Looking directly down from the bridge provides a strong sense of height and adds an exciting element to the experience.
At the same time, Zao Bridge is a popular photography spot. The vivid red structure stands out beautifully against the blue sky, green mountains, and calm waters of the reservoir. The combination of dramatic scenery and the unusual bridge design makes it a memorable stop for travelers exploring the area.
Explore the Surrounding Attractions
Futagawa Dam is located in an area with several other attractions, making it an excellent destination for a scenic day trip. Nearby, visitors can find Aragi-jima, a famous terraced rice-field landscape where traditional farmland follows the natural contours of the land.
There are also hot spring facilities in the surrounding area, offering travelers the opportunity to relax after exploring the mountains and lakeside scenery. Combining Futagawa Dam with Aragi-jima and a local hot spring can make for a rewarding excursion through the rural landscapes of Wakayama.
Convenient Access by Car
Futagawa Dam can be reached by car in approximately 40 minutes from the Arida Interchange. The drive itself is part of the attraction, as the route takes visitors through the peaceful mountain scenery of the Arida River basin.
Because of its location, the dam is particularly well suited to travelers exploring Wakayama by car. It can also be incorporated into a wider itinerary featuring rural villages, traditional agricultural landscapes, hot springs, and other natural attractions in the Aridagawa area.
A Scenic Destination Where Nature and Local Life Meet
Futagawa Dam and Zao Bridge offer a unique combination of natural beauty, engineering, and local life. The calm reservoir, surrounding mountains, seasonal flowers, and dramatic suspension bridge provide visitors with both relaxing scenery and an exciting experience.
Whether you visit during cherry blossom season, take a scenic drive around the lake, walk across Zao Bridge, or combine your trip with nearby attractions such as Aragi-jima and local hot springs, Futagawa Dam offers an opportunity to discover a quieter and more authentic side of Wakayama.
