Roten to Garden no Onsen Hooniwa is a garden-style onsen located in Ōdate, Akita Prefecture. Its sodium-chloride water flows at 42°C, pH 7.3. The establishment offers an indoor bath, an outdoor rotenburo bath and a sauna.
Insider tip — Hooniwa, the phoenix garden open-air bath, combines rotenburo soaking with ornamental garden design in the Odate suburban landscape. The mythic phoenix evokes rebirth and renewal, a hopeful theme for a city that has reinvented itself after the decline of copper mining and timber industries through tourism and Akita Inu culture.
