Kaike Onsen
A natural chloride spring that has continued since 1921 as the source spring and origin of Kaike. This sodium-calcium chloride spring, with a salty taste like seawater, is known as a hot spring that keeps you warm for a long time, and the warmth lingers pleasantly after bathing. The differently designed "O-buro" and "Yu-buro" alternate weekly, and you can take your time enjoying the variety of baths, including a circular bathing area with a ceiling shaped like an open umbrella and an open-air hot spring bath. Near the facility entrance, there is also a drinking spring using the very hot source water and a place to boil hot spring eggs.
