Lake Tazawa area

Lake Tazawa is the deepest in Japan at 423 meters, with water clear to a 15-meter depth. The bronze Princess Tatsuko statue on the western shore commemorates the woman who became the lake's dragon-spirit guardian; Goza-no-Ishi Shrine on the north shore frames a torii standing in the water. The real overnight draw is Nyuto Onsen up the mountain, a cluster of seven historic ryokan including Tsurunoyu, where the milky white outdoor bath has been continuously soaked in since the 1600s. A small ski resort sits between the lake and the onsen.
