Hotel Orion Motobu Resort & Spa – Jurassic Onsen Churaumi-no-yu
ホテル オリオン モトブ リゾート＆スパ ジュラ紀温泉 美ら海の湯
An onsen on the fifth floor of a resort hotel facing Emerald Beach, seven minutes' walk from the Churaumi Aquarium. Chloride water is drawn from Jurassic strata some 200 million years old, and the open-air bath looks across cobalt-blue sea to Ie Island. Two bathrooms — one with a dry sauna, one with steam — alternate daily between men and women, with cold plunge and outdoor rest area. Day use ¥2,150 including towel set, 6:00–10:00 and 15:00–23:00. A rare genuine hot spring in Okinawa, best enjoyed in the late afternoon after the aquarium.
