If you’re looking for a soothing escape in the middle of Osaka, Tennen Onsen Naniwa-no-Yu offers a chance to unwind with natural mineral waters amid urban scenery. This hot spring spa is celebrated locally for its therapeutic waters and the chance to take a break from sightseeing to relax like a local. While it might not be a sprawling onsen resort, it delivers a surprisingly authentic experience right in the city.

What makes this spot worth a visit? First, we love the mineral-rich waters pumped from 659 meters underground—a natural treat for your skin. Second, the views from the 8th floor let you soak while gazing over Osaka’s skyline, adding a unique perspective to your relaxation.
