Kyomachi Onsen's superb free-flowing waters and a tranquil Bona-style steam sauna
Miyazaki Ebino City
Jyubei no Yu sits in the Kyomachi Onsen area of Ebino, Miyazaki Prefecture. This facility, which also houses an udon restaurant and lodging, supplies every bath with free-flowing natural spring water drawn from 460 m underground — a sodium bicarbonate, sulfate, and chloride hot spring. The sauna is not a conventional dry sauna but a Bona-style steam bath that gently steams from below. With no TV and only the sound of steam, the quiet space offers deep relaxation. A mild cold plunge bath and outdoor open-air bathing surrounded by nature provide gentle restorative cooling that soothes both body and mind for sauna enthusiasts.
TypeNatural Hot Spring
The spring water is drawn from 460 m underground and is a sodium bicarbonate, sulfate, and chloride hot spring with a source temperature of 62°C. All tubs are supplied with free-flowing spring water, and the facility uses natural tourmaline mineral stone sourced from Brazil. The water is colorless and clear, offering a high-quality experience characterized by a slight astringent, mildly drying sensation together with a smooth, silky touch.

Rather than a typical dry sauna, this is a steam bath that works similarly to a Bona sauna, delivering heat from the seating and walls. There is no TV or background music; only the sound of steam can be heard, creating a meditative atmosphere. There is no thermometer, but it feels roughly 80°C, offering a steady, deep sweat.
Water QualityTap Water
Capacity4people
The cold plunge bath is located just beside the steam bath. The water temperature is around 18°C, set to a mild level rather than being overly cold. The water feels soft on the skin and gently cools the body warmed by the steam bath.
