Lake Shirakawa is an artificial lake formed by the Shirakawa Dam in Iide Town, Yamagata Prefecture. With a total water capacity of 50 million tons, it is one of the largest reservoirs in the Okitama region. The most iconic feature is the 'submerged forest'—a mesmerizing sight of trees standing beneath the water's surface. The interplay of light and water changes constantly with the time of day and season, drawing visitors from far and wide. Thanks to dam opening initiatives, the area is now a vibrant hub for leisure and tourism.
History & Cultural Background
The lake was created through the construction of the Shirakawa Dam. Following the Ministry of Construction's 'Dam Open to the Community' project in 1994, the dam was reimagened not just as a flood control facility, but as a center for regional revitalization. By 2003, it had grown into a major tourist destination attracting approximately 350,000 visitors annually. Today, the area promotes the 'opening of river spaces,' allowing authorized operators to offer activities such as glamping and various water sports while maintaining the natural environment.
Main Highlights
The scenery changes dramatically with the seasons. In early April, the contrast between the blooming Oyama cherry blossoms on the banks and the lingering snow on the Iide Mountains is breathtaking. In May, you may witness powerful water discharges from the dam. Summer features the 'SNOW Egg Festival' and spectacular fireworks, while late October brings peak autumn colors. In winter, the lake surface freezes over, creating a stark, beautiful landscape. The 'submerged forest' remains a top attraction for photographers year-round.
