Hot Plaza Suginoko Onsen, in Shichinohe, Aomori Prefecture, heats its sodium-chloride water to 42°C. The site offers an indoor bath, an outdoor rotenburo pool and a sauna.
Insider tip — Suginoko Onsen, the cedar sapling spring, takes its name from the plantation cedar forests that drape the Kamikita highland slopes above Shichinohe Town in green curtains of managed timber. The cedar here is Akita sugi, one of Japan finest structural timbers grown across the Tohoku mountain belt, and the Hot Plaza community complex combines modern recreational facilities with traditional spring bathing in a model of rural revitalization for Japan depopulating northern agricultural communities.
