"Tsurumiryokuchi Yumoto Suishun" is a large natural hot spring day-use facility in Tsurumi Ward, Osaka City, Osaka Prefecture. It offers extensive sauna facilities, including a far-infrared sauna, a medicinal herbal salt sauna filled with steam, and a men-only meditation sauna where you can enjoy self löyly. With a cold plunge bath and an open-air outdoor bathing area, it offers an exceptional refreshment experience. Its natural hot spring gushes up from deep underground ancient strata and is rich in minerals, with excellent heat-retaining properties. In the open-air rock bath, you can leisurely enjoy the free-flowing spring water. In addition, the facility also features a variety of themed bedrock bathing areas, a spacious relaxation lounge, a restaurant, and a fitness gym, allowing you to unwind both body and mind throughout the day.

A natural hot spring that gushes up from ancient strata deep underground. Rich in salt, it is said to have such strong heat-retaining effects that it is even called the "bath of warmth," because the salt that adheres to the skin helps prevent sweat from evaporating. In the open-air rock bath, you can luxuriate in this precious water as free-flowing spring water, and while feeling the abundant greenery and refreshing breeze, you can ease away fatigue from deep within your body.

A high-temperature sauna that gently warms you from the core with far-infrared heat. Auto löyly, where water is automatically dropped onto the sauna stones, is performed regularly, and the heat waves from the generated steam circulate back into the room to quickly induce perspiration. It is a comfortable space where you can relax while watching TV and work up a pleasant sweat.

A steam-filled mist sauna with the rich aroma of medicinal herbs. By gently rubbing the mineral-rich natural salt provided in the room onto your body, your skin becomes smooth and refined. Even if you are not good with high-temperature saunas, you can enter comfortably and enjoy deep relaxation while gradually warming up.

A calming sauna wrapped in silence, ideal for mindfulness and for taking time to reflect deeply on yourself. By pressing the dedicated switch whenever you like, auto löyly is activated and a refreshing wave of heat rolls in. With your eyes quietly closed, you can fully savor the sensation of heat penetrating your body and your mind and body becoming clear.

A cold bath that crisps and tightens a body that has been thoroughly warmed in the sauna. By rapidly cooling your overheated body, it helps retain the warmth you've built up and enhances the heat-retaining effect. After cooling down well, you can enjoy open-air bathing on the wood deck or in a totonoi chair prepared in the outdoor area.
