Umineko Onsen Yurakkusu is located in Yamada, on the coast of Iwate Prefecture. The sodium-chloride water is heated to 42°C, feeding an indoor bath, an outdoor rotenburo pool and a sauna.
Insider tip — Umineko Yurakkusu, the seagull relaxation spring, celebrates the black-tailed gulls that haunt the Sanriku ria fjords around Yamada-machi. Yamada was heavily damaged in the 2011 Great East Japan Earthquake tsunami but rebuilt around its oyster aquaculture industry — the sheltered Yamada Bay produces Pacific oysters of exceptional quality whose meaty texture and mineral richness have earned premium prices in Tokyo restaurant markets since the recovery.
