Ozakura Onsen Yurakuri, in Yurihonjō, Akita Prefecture, offers sodium-chloride thermal water at 40°C, with an indoor bath, an outdoor rotenburo and a sauna.
Insider tip — Yurihonjō sits on Akita's Sea of Japan coast below the majestic Chokai-san volcano — nicknamed 'Dewa Fuji' for its perfectly symmetrical cone rising 2,236 meters above the coastal plain. The city's Ozakura (cherry blossom) festival celebrates spring along the Yuri River. Offshore, the remote Tobishima Island hosts one of Japan's premier seabird sanctuaries, with dramatic cliffs and rare black-tailed gulls. Yurakuri (leisurely) onsen captures the relaxed, seasonal pace of this beautiful Sea of Japan coast.
