The components of famous hot springs from various regions across Japan, such as Kusatsu, Beppu, and Noboribetsu, have been analyzed to create a bath that closely resembles them. You can experience the effects when you actually bathe. Enjoy the characteristics of each spring quality while feeling as if you are traveling to different hot spring areas.

This hot spring originates from fossil seawater that springs from 1,000 meters underground. It contains iodine at a concentration 1,500 times that of seawater, known for its rare spring quality worldwide. It is also rich in metasilicic acid and bicarbonate ions, providing a smooth texture with expected skin-beautifying effects. Due to the characteristics of the strong saline chloride spring, a salt film forms on the body, offering high heat retention, and the warmth from the core lasts long after bathing. From the open-air bath, you can closely watch airplanes taking off and landing at Narita Airport, experiencing both a sense of openness and an extraordinary feeling. In the private bath 'Kuukai,' you can indulge in the luxury of 100% natural spring water. It is expected to be effective for neuralgia, muscle pain, joint pain, cold sensitivity, and fatigue recovery, allowing you to fundamentally heal travel fatigue by combining the sauna and hot springs.
