Natural hot spring boasting a luxurious 120cm-deep cold plunge bath and a spacious sauna
Saga Omachi Town
Omachi Onsen Hijiri no Yu is a day-use hot spring in Omachi, Saga Prefecture. It features slightly viscous natural hot spring water (a sodium chloride spring) and prides itself on well-equipped facilities that attract sauna enthusiasts. The combination of a hotter far-infrared sauna that can accommodate more than 20 people and an outdoor cold plunge bath fed by groundwater with a 120cm depth is superb. With a spacious outdoor area for cooling off in the open air and a variety of baths, you can enjoy deep relaxation for both body and mind.
TypeNatural Hot Spring
A sodium chloride spring rising from 1,500 meters underground. The slightly cloudy water has a silky texture that leaves skin feeling moist and makes it less likely to get chilled after bathing. You can enjoy the source water in a variety of baths, including a large open-air bath set in nature and reclining baths.
Sauna TypeDry Sauna
Stove TypeInfrared Heater
Capacity20people
A spacious three-tier dry sauna equipped with gas far-infrared heaters that can accommodate more than 20 people. The wide benches allow for comfortable seating. It provides a level of heat and humidity that feels stronger than the thermometer suggests, set to induce heavy sweating even during a short session.
Water QualityNatural Water (Groundwater, Spring, etc.)
Capacity10people
The facility's famed large cold plunge bath in the outdoor area. The rectangular tub is knee-deep at the front and reaches an impressive 120cm depth toward the back.
