Insider tip — Mitsuya (三ツ屋) Onsen is in northern Osaka near the Yodogawa River — historically Japan's great commercial waterway, along which barges from Kyoto and Fushimi Inari brought sake and rice to the merchant capital of Osaka. This neighborhood sento serves a working-class riverside district with classic Osaka hospitality; 'Mitsuya' (three houses) reflects the traditional merchant quarter origins of the area.
