Aichi Gamagori City
A sky-high open-air bath and a skin-friendly beautifying spring overlooking the stunning view of Mikawa Bay from the highest point on the Nishiura Peninsula
Sky-Sea Resort Inn Suirei is a hot spring ryokan in Nishiura-cho, Gamagori City, Aichi Prefecture. Perched on the highest hill in Nishiura Onsen, its all-ocean-view rooms overlook the sweeping panorama of Mikawa Bay. Its greatest draw is Amane no Yu, a sky-high open-air bath on the rooftop, where you can spend blissful moments surrounded by unblocked views of nature and the sea breeze. On the first floor, the large public bath features an observatory open-air bath drawing from Bihaku-sen, an alkaline simple spring that is gentle on the skin. In addition, there are a variety of bathing facilities, including paid private reservable open-air baths, a full-scale stone sauna that slowly promotes detox at a low temperature, and a foot bath, all designed to soothe the fatigue of everyday life.

Most of what we surveyed never even made it onto this site. This book is a further cut from what did. Our editor bathed in every onsen and sauna in it, and wrote only what they confirmed on the ground.
