Ota Onsen Yamabuki no Yu is located in Hitachiōta, Ibaraki Prefecture, northeast of Tokyo. Sodium-chloride thermal water rises at 40°C, feeding an indoor bath, an outdoor rotenburo, and a sauna.
Insider tip — 'Yamabuki no Yu' (山吹の湯 — mountain rose bath) is named for the brilliant yellow Kerria japonica flowers that bloom along Ibaraki's mountain streams in April. Hitachi-Ōta sits in the Naka River hills of northern Ibaraki; the nearby Ryūjin Dam Lake and Satomi Park offer spectacular scenery, and the annual Hitachi Seaside Park tulip and nemophila (baby blue eyes) festivals make this one of Kanto's most rewarding flower-viewing regions.
