A satoyama ryokan proud of its Radon thermal room and Bijin no Yu
Kagoshima Satsumasendai City
Ryokan Satsuma no Sato is a purely Japanese-style inn set in the satoyama countryside a short distance from the Ichibino Onsen area of Satsumasendai City. Day-use bathing is available, and the inn prides itself on Bijin no Yu, a 100% free-flowing natural hot spring boasting pH 9.8. The sauna facilities include Kyushu's first Radon thermal room. The room's walls are lined with DOLL STONE tiles containing natural radium, and the far-infrared rays and trace amounts of radon they emit promote steady perspiration at a low temperature. The compact cold plunge bath is designed for one person. Surrounded by quiet satoyama nature, this is an exquisite hideaway where guests can relax body and mind away from the city's bustle.
