Ujina Tennen Onsen Hono Yu, in the Ujina district of Hiroshima, offers sodium-chloride thermal water at 40°C. It has an indoor bath, an outdoor bath (rotenburo) and a sauna.
Insider tip — Ujina is Hiroshima's historic port district — the military harbor from which Imperial Japanese troops embarked for campaigns across Asia and the Pacific. Transformed after WWII into a civilian port and ferry terminal, Ujina now connects Hiroshima to the Seto Inland Sea islands including Miyajima. Hono Yu (Flame of the Bath) taps coastal sodium-chloride springs in a district now entirely devoted to peace, maritime commerce, and the quiet rhythms of a port neighborhood rebuilt from devastation.
