Ipponmatsu Onsen Akeboneso sits in Ainan, Ehime Prefecture, at the southern tip of Shikoku. The sodium-chloride water reaches 41°C, with an indoor bath, an outdoor rotenburo and a sauna.
Insider tip — Akebonoso, the dawn lodge, serves Ainan Town on the remote southern Pacific coast of Ehime Prefecture where Cape Sata direction headlands fall straight into the Bungo Channel. The fishing communities of Ainan have maintained traditional Pacific coastal harvesting for centuries in one of Shikoku most isolated and unspoiled coastal landscapes, where the dawn light across the Tosa Bay gives this spring its evocative name of morning hope.
