Takatsuki Shin Onsen, in Osaka Prefecture, offers sodium-chloride thermal water at 37°C (pH 7.3). An indoor bath, an outdoor rotenburo and a sauna are available.
Insider tip — A neighbourhood onsen in Takatsuki, positioned between Osaka and Kyoto. The 'shin' (new) facility taps natural hot spring waters — a rarity in this highly urbanised corridor. Great stop on a Kyoto–Osaka day trip.
