Tazawako Onsen is a hot spring resort area on the shores of Lake Tazawa in Semboku City, Akita Prefecture, Japan — the deepest lake in Japan and one of the most strikingly beautiful, famous for its extraordinary cobalt-blue color produced by its remarkable depth and purity. The alkaline bicarbonate thermal waters of the onsen area complement the serene lakeside setting and are valued for their skin-nourishing properties and their warming, relaxing effect in the cold Akita winters. The legendary figure of Tatsuko — a young woman said to have drunk from a sacred spring and been transformed into a dragon guardian of the lake — is one of the most beloved legends of Tohoku, and her golden statue on the lakeshore gives Tazawako its iconic image. Tazawako Onsen offers a deeply atmospheric combination of extraordinary natural lake beauty, rich folkloric tradition, and the restorative pleasures of fine Tohoku hot spring bathing.
