The Mysteries of Lake Tazawa: Exploring the secrets and legends behind Japan’s deepest lake


The Legend of Princess Tatsuko

Deep in the mountains of Akita Prefecture lies Lake Tazawa, the deepest lake in Japan with a depth of 423 meters. But it’s not just its depth that makes it a fascinating destination for travelers. Lake Tazawa is also shrouded in legends and mysteries that have been passed down for generations.

One of the most famous legends is that of Princess Tatsuko.

According to the legend, a beautiful princess named Tatsuko lived near the lake hundreds of years ago. One day, she prayed to the god of the nearby mountain, Mount Nyuto, for eternal beauty and youth. The god granted her wish, but with one condition: she had to remain a virgin for all eternity. The princess agreed, but soon regretted her decision when she fell in love with a young man. They tried to run away together, but the god of Mount Nyuto transformed Tatsuko into a dragon and struck her lover with a thunderbolt, killing him instantly. Tatsuko’s dragon form sank into the lake, and it’s said that her spirit still lives on in the waters of Lake Tazawa.

The Mysterious Color of Lake Tazawa

Another mystery of Lake Tazawa is the unusual color of its waters. The lake has a deep blue color that changes depending on the time of day and weather conditions. Scientists believe that the color is caused by the unique combination of minerals in the lake, but locals have their own theories. According to one legend, the blue color is the tears of Princess Tatsuko, who wept for eternity after losing her lover. Another legend says that the lake was formed by the tears of a mother who cried for her children who were taken away by a demon. Whatever the reason, the color of Lake Tazawa adds to its mysterious and otherworldly atmosphere.

Exploring Lake Tazawa

Aside from the legends and mysteries, Lake Tazawa is also a gorgeous destination for sightseeing and outdoor activities. Visitors can take a boat ride on the lake, hike around its scenic trails, or relax in the nearby hot springs. The lake is surrounded by breathtaking autumn foliage in the fall, making it a popular spot for photography. Whether you’re interested in its legends or just want to take in its natural beauty, a trip to Lake Tazawa is a must-see destination in Japan.
