Mando no Yu, in Yabu, Hyogo Prefecture, draws natural sodium-chloride water at 41°C. Indoor bath, outdoor rotenburo and sauna make up the facility for a relaxing stopover.
Insider tip — Mando no Yu, the ten-thousand-lights spring, serves Yabu City in the Tanba-Tajima mountain corridor of Hyogo Prefecture where the Nishiki River valley connects the San-in coast to the Kyoto Basin through forested ridges and traditional tanada terraced rice paddies. The spring has become associated with the Gokaku tradition — its lucky name meaning exam success drawing students from across the Kinki region who visit before February university entrance examinations to seek the blessing of the spring waters for their academic endeavors.
