In Kimitsu, Chiba Prefecture, Nomizo Onsen Senju no Yu draws sodium-chloride water at 41°C. The facility brings together an indoor bath, an outdoor rotenburo bath and a sauna.
Insider tip — In the forested hills of southern Chiba on the Boso Peninsula, near the famous Nomizo Falls where temple maidens once purified themselves beneath cascading water, Senju no Yu (thousand hands waters) references the thousand-armed Kannon Buddhist deity; the lush valley setting makes this one of the more atmospherically contemplative onsen within easy reach of Tokyo.
