Choju Onsen is a bathhouse in Hachinohe, Aomori Prefecture, in northern Japan. Its sodium-chloride waters emerge at 41°C and feed an indoor bath and an open-air rotenburo, alongside a sauna.
Insider tip — Choju Onsen (longevity spring) in Hachinohe appropriately channels the longevity traditions of the Tohoku region, where dietary discipline, fresh seafood, and community bathing culture have contributed to some of Japan's highest life expectancy rates; the mineral waters serve the port city's fishing and industrial workforce with straightforward restorative bathing.
