Senshu Onsen Kansai International Airport
Relax and unwind in the natural hot spring Senshu Onsen Kansai Airport, where you can enjoy a leisurely soak while taking in stunning views of Osaka Bay. On clear days, you can see as far as Mount Rokko and Awaji Island. Enjoy the sea breeze in the open-air bath while watching planes take off and land or ships sail by. Beyond the spectacular views, the hot spring itself is a highlight. The Senshu Onsen, drawn from 800 meters underground, is known as Bijin no Yu ("Beauty’s Bath") for its skin-beautifying properties.
This is a real natural hot spring—the water feels super smooth, not like those "fake" ones. My skin felt so soft after soaking, and I was totally relaxed.
