With its riverside rotenburo (outdoor bath), Okutsu Onsen features numerous elegant inns and accommodations. Because soaking in the hot spring’s waters is said to make one’s skin white and smooth, this onsen is famously known as “Bijin no Yu” (Onsen of Beauty). “Ashibumi Sentaku,” also known as the “Washing Dance,” is performed by women in kimonos holding pails while stamping on garments and making washing motions with their toes. This “dance,” a noted attraction at Okutsu Onsen, is performed in the rotenburo on Sundays and public holidays from late March to early December. Visitors are welcome to enjoy the “Ashibumi Sentaku” at no charge as well as the area’s beautiful seasonal landscapes including fall foliage in autumn and snowfall in winter.
