Japanese Mud-Baths

Hakusuikan Ryokan
Ibusuki, Kagoshima prefecture
Besides its luxurious facilities and beachside setting, Hakusuikan Ryokan offers a bathing area with pools of different temperatures, a large outdoor hot spring, a steam room and a sauna. But the resort is famous for its black sand baths-visitors are buried up to the neck in warm sand heated by natural hot springs-which they say increase blood circulation and refresh the body by discharging waste through perspiration. Your most difficult choice here: choosing to stay in a Western-style room or a Japanese-style tatami room facing the water.
