Karuizawa Onsen is a hot spring in Ōdate, Akita prefecture, in northern Japan. Its sodium-chloride water reaches roughly 40°C. The bath house has an indoor pool, an outdoor rotenburo bath and a sauna, in the style of rural Japanese onsen.
Insider tip — Ōdate is the birthplace of the Akita Inu — the loyal, noble dog breed whose most famous member, Hachiko, waited for his owner at Shibuya Station for nine years after his master's death. The Akita Inu Museum in Ōdate celebrates this breed's history and cultural significance. The nearby Shirakami Sanchi UNESCO World Heritage beech forest is one of Japan's last virgin temperate broadleaf forests. Karuizawa Onsen in this northern Akita city offers a restorative soak after exploring the forested heartland.
