Shirahone Onsen (白骨温泉, literally "white bone hot spring") is a small onsen town in the Northern Japan Alps. The town is a loose collection of a dozen or so ryokan along the slopes of a steep valley, which lies near famous alpine nature spots such as Kamikochi and Norikura. Shirahone Onsen gets its name from its milky white spring water, which is nearly opaque with magnesium and calcium sediments and is believed to relieve gastrointestinal ailments.
There is one public bath in Shirahone Onsen. Furthermore, many of the town's ryokan open their baths to day trip visitors during the day for a few hundred yen. Among them is the Awanoyu with its large mixed outdoor bath that is often seen in tourist promotional materials about Shirahone Onsen.
