Yuppo no Sato Foot Bath

Yuppo no Sato (湯っ歩の里) is a foot-bath-only facility in the Shiobara onsen area, built around what the site claims is Japan's largest indoor foot bath at 60 meters long. The bath is split into two parallel channels, and the floor is divided into six zones, each with a different stone texture to massage the soles as you walk. The spring water flows straight from the source without heating or dilution (kakenagashi). A drinking fountain on the grounds draws from the same spring, and benches alongside the channels let you sit and soak. There is no full-body bathing here.
