Aoyama Onsen is a neighbourhood bathhouse located in Osaka. Its sodium-chloride thermal water flows at 41°C (106°F), in a facility that includes an indoor bath, an outdoor rotenburo bath and a sauna.
Insider tip — Aoyama (青山 — blue/green mountain) Onsen draws dark sodium-chloride water from deep Osaka Basin formations in northwestern Osaka. The 'aoyama' image — distant mountains appearing blue through atmospheric haze — is a classic image in Japanese and Chinese poetry symbolizing longing and distant beauty. This urban sento serves a working-class northern Osaka neighborhood near the Yodogawa River embankment, where autumn evenings see the river glow with the lights of fireworks barges.
