Lukewarm BathAbout
ONCRI is a ryokan in Furuyu Onsen, Saga, built around a large bathhouse with fifteen different ways to bathe across its men's and women's sides: an open-air bath facing Mt. Tenzan (天山), lying and standing baths, a steam bath, a dry sauna, a hinoki wood bath, a cold plunge, and a foot bath. The spring water here runs noticeably milder than a typical hot bath, known locally as nuruyu (ぬる湯), so people settle in for a long soak rather than a quick one. Day visitors can use the baths and eat at the restaurants without staying the night. Only the detached JIBOH cottage rooms have their own onsen bath; the other room types have an ordinary bath.
