Insider tip — Ayauta Onsen Yubunemichi sits in the gently rolling hills of Ayauta district between Sakaide and Marugame in Kagawa, drawing iron-rich brine water from moderate depths in the coastal sedimentary sequence. The amber-coloured baths are valued locally for their warmth and the traditional tub-road bathing style evoked by the facility's name, yubunemichi meaning the path of the bath vessel. Guests can enjoy views over saltpan-flat rice paddies toward the Seto Inland Sea from the hilltop rotenburo. The facility serves as a community gathering point for nearby agricultural villages and maintains a pleasantly unhurried atmosphere.
