Yunoura Onsen (Shiki no Yu Beer Kobo), in Imabari, Ehime Prefecture, offers sodium-chloride thermal water at 41°C, with an indoor bath, an outdoor bath (rotenburo) and a sauna available.
Insider tip — Shiki no Yu Beer Kobo is Japan only facility combining an onsen with an on-site craft brewery, where visitors soak in Seto Inland Sea coastal thermal water before sampling fresh ales brewed with Ehime spring water in the adjacent Beer Workshop. The Yunoura thermal spring feeds both the soaking pools and the brewing kettle water supply, creating a unique wellness-and-craft-beverage fusion that has made this Imabari destination a model for innovative Japanese bath culture.
