Nagai Dam forms the beautiful Hyakushu Lake, located west of the urban center of Nagai City in Yamagata Prefecture. Completed in 2011, the area surrounding the dam is a scenic destination embraced by rich natural environments. The vast expanse of the water surface, framed by surrounding mountains, offers a changing landscape through every season, providing a sense of peace and healing to all who visit.
Nagai Dam was constructed primarily for water resource management and flood control. Since its completion, the area has evolved into a beloved community hub and a popular tourist destination, utilizing its stunning scenery to attract both locals and visitors. Hyakushu Lake serves as a symbol of coexistence with nature, acting as a center for promoting the region's charm through seasonal events and outdoor activities.
The greatest attraction is the seamless integration of the vast lake surface with the surrounding mountains. In autumn, the scenery is particularly spectacular as the surrounding trees turn vibrant shades of red and gold, reflecting beautifully on the water. The architectural view of the dam structure itself and the panoramic vistas from bridges like the Ryujin Bridge offer a unique visual experience. Depending on the season, you can also enjoy specialized water-based activities.
