At 423.4 meters deep, Lake Tazawa is the deepest lake in Japan, surpassing Lake Shikotsu.
The lake's water has a unique, bright turquoise hue caused by the scattering of light in its exceptionally deep, clear water.
Despite the cold climate of Akita, the lake's great depth keeps its water temperature relatively constant, preventing it from freezing in winter.
The lake was formerly home to a unique subspecies of salmon called 'kunimasu,' which was believed to be extinct for 70 years until its rediscovery in 2010.
The golden statue of Tatsuko, a legendary figure from local folklore, stands on the western shore as a prominent landmark.
Lake Tazawa is Japan's deepest lake, reaching a maximum depth of 423.4 meters. Located in Semboku, Akita Prefecture, it is a volcanic caldera lake renowned for its high transparency and distinctively deep blue, turquoise water. The lake's depth prevents it from freezing even during the harsh winters of the Tohoku region. It serves as a central feature of the Towada-Hachimantai National Park. Visitors can explore the perimeter via a circular road or utilize sightseeing boats for mid-lake views. The surrounding area features forested slopes that turn vibrant shades of red and orange during the autumn foliage season. Several bronze statues and observation points are positioned along the shoreline to highlight the lake's geography.

Check the local lake water visibility conditions before planning boat tours to ensure optimal sightseeing.
Bring a polarizing filter for your camera to better capture the deep blue color of the water without surface glare.
Avoid relying solely on walking, as the lake circumference is over 20 kilometers, making it impractical to traverse on foot.
Sightseeing boat services are typically suspended during the winter season due to ice and weather conditions.
