Genjigaoka Onsen, in the Kinki region around Osaka, offers mildly acidic (pH 6.3) iron-rich water at 41°C, along with an indoor bath, an outdoor rotenburo and a sauna.
Insider tip — Genjigaoka Onsen occupies a quiet residential street in the Higashisumiyoshi area of Osaka, drawing iron-rich hot water from the deep Osaka Group sedimentary formation. The amber baths are beloved by regulars for their blood-warming properties and the facility preserves much of its Showa-era tile aesthetic. The name references the Genji Monogatari hillside nearby, lending a literary atmosphere to an otherwise modest local bathhouse. Sunset visits, when the lanterns flicker on outside, are particularly atmospheric.
