Hot Spring Information
Hot Spring
Enjoy the natural hot spring that wells up from underground in the open-air bath. The texture of the water is soft, gently enveloping the skin. The warmth of the hot spring further promotes the circulation boosted by the sauna and cold plunge bath, warming you from the core. The open-air bath offers a sense of freedom, allowing you to soak while gazing at the sky. The indoor bath also features a carbonated bath, where fine carbonated bubbles adhere to the skin, promoting blood circulation. The carbonated bath is set at a lower temperature, suitable for long soaks. By alternating between the hot spring and carbonated bath, you can thoroughly relieve your body's fatigue.
Sauna & Cold Bath Information
High-Temperature Sauna
The interior is spacious and can accommodate many users at once. It offers a temperature range that allows you to sweat thoroughly, warming your body from the core with the effect of far-infrared rays. The convection stove distributes heat throughout the room, allowing you to choose your preferred heat level by feeling the temperature difference depending on the seating position. The facility conducts four types of löyly, and during events, steam rises rapidly, accelerating sweating. You can enjoy a relaxing sauna time in a quiet space.
Salt Sauna
In a low-temperature sauna room, you can sweat slowly while applying salt to your body. The osmotic pressure of the salt draws out waste products from the skin surface, providing a beauty effect. With a softer heat than the high-temperature sauna, breathing is easy, allowing for longer stays. After applying salt and waiting a few minutes, the salt dissolves with sweat, leaving your skin smooth. During löyly events, humidity increases, enhancing the effect of the salt. By alternating with the high-temperature sauna, you can enjoy a diverse sweating experience.
Cold Plunge Bath (Jacuzzi)
The cold plunge bath, located right outside the sauna room, is equipped with a jacuzzi function. The water temperature is moderately cold, providing a pleasant cooldown for your body heated in the sauna. The water is processed through a nanotechnology electronic wave device, making it softer and gentler on the skin than tap water. The jacuzzi bubbles envelop your body, enhancing fatigue recovery.
