Yu-Rakuen (Shimoda Onsen), in Oirase-cho, Aomori prefecture, draws on a sodium-chloride spring at 41°C. Visitors have access to an indoor bath, an outdoor rotenburo and a sauna.
Insider tip — In Oirase, a town adjacent to the port city of Hachinohe in southeastern Aomori, Yu-Rakuen (hot spring pleasure garden) offers relaxed mineral bathing in the coastal Sanriku region; the nearby Oirase Stream — an entirely different and famous gorge-stream flowing from Lake Towada — is worth the short detour for its autumn foliage, making this onsen a convenient base for exploring southeastern Aomori.
