Yawatahama Onsen is a thermal facility in Yawatahama city, Ehime Prefecture on Shikoku Island, a historic fishing port on the Uwa Sea facing the Bungo Channel where siliceous geothermal waters from the Shikoku basement rocks provide a restorative bathing experience in a city celebrated for its mandarin orange production and vibrant morning market culture. The city's onsen tradition is integral to the daily life of Yawatahama's fishing and farming communities, with the local sento public bath serving as a social gathering place in the tradition of Japanese communal thermal culture. The combination of siliceous thermal bathing, abundant fresh seafood from the Uwa Sea, and the scenic coastal landscape of the Sadamisaki Peninsula — Japan's longest and narrowest cape — makes Yawatahama a rewarding destination on the lesser-traveled western coast of Shikoku.
