Futatsuno Dam is an arch dam located in Totsukawa Village, Yoshino District, Nara Prefecture. Completed in 1962, it was built across the main channel of the Totsukawa River, which flows through the Kii Mountains. The dam and the surrounding rugged mountains create a striking landscape that has become one of the area’s notable sightseeing attractions. The lake formed by the dam, Futatsuno Dam Lake, is one of the signature views of Totsukawa Village, where the natural environment and human activity exist side by side.
Futatsuno Dam Lake is an artificial lake covering approximately 200 hectares. Located alongside National Route 168, it is easy to visit during a scenic drive through the region. Surrounded by mountains, the lake offers changing views throughout the year. In autumn, colorful foliage is reflected on the water, creating a particularly beautiful scene that attracts visitors.
Inns and shops serving the Totsukawa Onsen hot-spring area are scattered around the lakeshore. The area is an appealing destination for travelers who want to combine sightseeing and outdoor exploration with a relaxing stay at a hot-spring inn.
Futatsuno Dam Lake is also known as one of Japan’s important wintering grounds for mandarin ducks. From November through March, more than 2,000 birds may arrive, and their numbers are said to account for around five percent of the national total.
The lake’s left bank has no roads or settlements and is covered with secondary woodland dominated by Japanese chinquapin and evergreen oaks. The abundant acorns provide a valuable food source, while the quiet surroundings offer a suitable habitat for waterbirds. These favorable conditions help attract large numbers of mandarin ducks each winter, making the lake an excellent destination for birdwatching and nature appreciation.
Several suspension bridges cross the area around Futatsuno Dam Lake, including Futatsuno Ohashi Bridge, Sarukai Bridge, and Kominoe Bridge. These bridges offer different perspectives on the lake and surrounding mountains.
Futatsuno Ohashi is particularly exciting, measuring 193 meters in length and standing 35 meters above the lake. Walking across it gives visitors the sensation of crossing directly over the water, with expansive views beneath their feet. Some of the bridges also serve as everyday routes for local residents, offering travelers a glimpse into the daily life of this mountainous community.
The area surrounding Futatsuno Dam Lake is home to several waterfalls, including Junidaki Falls, Fudo Falls, and Ootai Falls. These natural attractions offer peaceful places to pause and appreciate the scenery of Totsukawa Village.
Junidaki Falls is estimated to have a drop of approximately 80 to 100 meters. Located beside National Route 168, it can be viewed without a long hike, making it a convenient stop during a drive around the region. The quiet flow of water, framed by the surrounding greenery and mountains, captures the tranquil beauty that makes Totsukawa so appealing.
