Chiba Shibayama
Narita Airport Onsen Sora no Yu is a bathing complex located in Shibayama Town, Sanbu District, Chiba Prefecture. It is directly connected by a free shuttle bus from Narita Airport Terminal 2, allowing you to soak in natural hot springs that spring from 1,000 meters underground while watching airplanes. The high-temperature dry sauna is equipped with an automatic löyly function, providing a 90°C heat wave that promotes sweating, and you can quickly cool down in the cold plunge bath with natural underground water. The finishing touch is a strong saline chloride spring that warms you from the core, making it hard to feel chilled after bathing. The facility also includes a stone sauna, capsule hotel, dining area, fitness gym, and a relaxation area with 8,600 manga books, making it a comfortable airport-connected hot spring resort where you can spend the whole day.
TypeArtificial Hot Spring
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.
TypeNatural Hot Spring
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.
Sauna TypeDry Sauna
Stove TypeConvection Stove (Sauna Stone)
Capacity25people
The room temperature is high, and the automatic löyly function periodically generates steam. Using a convection stove with sauna stones, it provides a good balance of heat and steam, promoting a thorough sweat. The spacious area includes a TV, allowing you to relax while sweating. When steam fills the room, humidity rises, and the perceived temperature increases rapidly. You can imagine the takeoffs and landings at Narita Airport while sweating out travel fatigue.
Water QualityNatural Water (Groundwater, Spring, etc.)
Capacity3people
Cold well water drawn from underground is used in a continuous flow. The water temperature is suitably cold, allowing you to cool down thoroughly after heating up in the high-temperature sauna. The underground water has a unique softness and good water quality, allowing for extended soaking. Due to the continuous flow, fresh water is always supplied, maintaining a refreshing sensation. After alternating between the sauna and cold plunge bath, you can enjoy a leisurely outdoor air bath in the relaxation area or open-air bath area.
