Takamatsu Crater no Yu, also known as Tennen Onsen Kirara, is located in Takamatsu (Kagawa). Its sodium-chloride water at 41°C feeds an indoor bath and an open-air outdoor bath, with a sauna as well.
Insider tip — Kirara, meaning glittering crystal, names this Takamatsu spa built around a crater-themed design concept. Takamatsu anchors Shikoku, and the exquisite Ritsurin Garden, one of Japan finest strolling gardens created by the Matsudaira lords over a century, is just minutes away for a memorable post-soak walk.
