Fukuzumi Onsen is located in Amagasaki, Hyogo Prefecture, an industrial city near Osaka. Sodium-chloride thermal water flows at 41°C through an indoor bath, a rotenburo, and a sauna.
Insider tip — Fukuzumi Onsen is a classic neighborhood sento in Amagasaki's residential quarter — 'Fukuzumi' (福泉) means 'blessed spring.' Amagasaki's local identity is famously distinct from its Osaka and Kobe neighbors; the city's down-to-earth character, affordable street food scene (especially kushikatsu and monjayaki), and Hanshin Tigers baseball fanaticism create one of the Kansai area's most authentic urban atmospheres.
