Tenmabayashi Onsen sits in Shichinohe, Aomori Prefecture. It offers sodium-chloride water at 42°C, along with an indoor bath, an outdoor rotenburo pool and a sauna.
Insider tip — Tenmabayashi Onsen, the divine horse forest spring, serves Shichinohe-machi (Seven Forts Town) where the Nanbu clan ancient mountain castle district protected the central Aomori Kamikita highland bowl from Abe clan incursions in the 11th-century Zenkunen War. The divine horse theme echoes the celebrated Nanbu horse breeding that made northern Tohoku Japan most important cavalry livestock region for a thousand years, with the last Nanbu horse studs still operating in the surrounding highlands.
