Tennen Onsen Naniwanoyu

Tennen Onsen Naniwanoyu is a modern, rooftop natural hot spring complex in northern Osaka, offering a rare outdoor bathing experience high above the bustling city. It is highly worth visiting for its 100% natural, skin-softening alkaline spring water pumped from deep underground, alongside various saunas, jet baths, and micro-bubble pools. Expect a relaxing local bathhouse atmosphere, complete with stone baths surrounded by greenery under the open sky.
