Nagatoro Onsen is located in Ōdate, Akita Prefecture, a northern Japanese region rich in hot springs. The sodium-chloride water reaches 42°C, pH 7.3. An indoor bath, an outdoor rotenburo bath and a sauna are available on site.
Insider tip — Nagatoro Onsen serves a valley community on the western edge of Odate, where the Nagatoro stream drains cedar-forested hills into the Yoneshiro River. The spring is typical of Odate area baths — saline, deeply warming, and frequented by outdoor workers and lumbermen at the end of long days in the forest.
