About Oashi Kogen Onsen Unkai
An onsen lodging facility nestled on a plateau at an elevation of about 500 m in Mimasaka, Okayama Prefecture. From autumn through winter on early mornings, it is known as a scenic spot where you can look out over the sea of clouds, just as its name suggests. Its alkaline simple hot spring, pumped up from 1,500 m underground, is famous for its smooth, silky texture and skin-beautifying waters. From the open-air baths, you can gaze out over the mountains and enjoy the scenery of all four seasons. The sauna is a gas-fired far-infrared dry type with gentle heat and a pleasantly humid feel, and paired with the cold plunge bath using natural spring water, it delivers an exceptional totonou experience. The resort also offers lakeside bungalows, a restaurant, grand golf, and more.
