Hanbei Onsen, in Nishi Ward, Hiroshima, draws sodium-chloride thermal water at 40°C. The bathhouse includes an indoor bath, an outdoor bath (rotenburo) and a sauna.
Insider tip — Hiroshima's residential western districts, spreading into the foothills of the Chugoku mountains, carry a different character from the memorial city center: quiet suburban neighborhoods, family temples, and the rhythms of ordinary life rebuilt over eight decades. Hanbei Onsen is a neighborhood institution for these communities. An evening soak here — after a day spent at the Peace Memorial Museum — provides a meditative return to the domestic warmth that the city's reconstruction was ultimately about restoring.
