Yayoinoyu Onsen is a natural day-spa onsen located about 15 minutes by car from Obihiro Station. At this onsen, the hot spring comes bubbling up from 1,600 meters below the earth, and the sodium chloride content in the water is easy on the skin. Sodium chloride springs have heat-retaining benefits, which is an especially attractive feature for people who are sensitive to cold. Here, visitors can refresh themselves from the fatigue of sightseeing through many different kinds of baths, including tub baths, sleeping baths, cave onsen, and stone baths, as well as exfoliating beauty treatments and chiropractic massages. After relaxing in the onsen, we recommend tasting dishes that use Hokkaido-local rice nanatsuboshi.
