Located in Miki, Kagawa, Shikoku, Itoyori Onsen is a traditional onsen fed by sodium-chloride water. The water emerges at around 41°C. Facilities include an indoor bath, an open-air bath (rotenburo) and a sauna. A quiet wellness break away from the bustle.
Insider tip — Itoyori Onsen sits in Miki Town, Kagawa Prefecture on Shikoku island, where coastal proximity produces mildly saline, sodium-chloride waters typical of the Seto Inland Sea region. The inland sea's sheltered geography and mild climate make Kagawa a relaxed destination for onsen enthusiasts combining bathing with visits to Kotohira Shrine or the 88-temple Shikoku pilgrimage circuit. The warm saline waters are especially valued for their skin-softening and warming properties. Plan a visit in autumn when the persimmon orchards and rice fields surrounding the facility glow with seasonal color.
