What Is Lake Tazawa? One of Akita’s Most Scenic Destinations
Lake Tazawa is a nearly circular caldera lake in Semboku City, Akita Prefecture, with a circumference of about 20 kilometers.
The clear water shifts to lapis blue, turquoise, and deep blue depending on the sunlight and viewing angle, changing its appearance with the seasons.
Because the lake is so deep, it is less likely to freeze even in winter, which is another reason you can enjoy the lakeside scenery throughout the year.
One of the charms of Lake Tazawa is the “Princess Tatsuko Legend” associated with the lake.
The story tells of Tatsuko, a young woman who wished for eternal beauty, transformed into a dragon, and became the guardian of Lake Tazawa.
The golden Tatsuko Statue stands by the lakeshore and is a popular photo spot visited by many people as a symbol of Lake Tazawa.
