Another famous onsen on Hachijo Island. This one is all the more remarkable because it’s free! Despite this it is probably the most aesthetically pleasing onsen on the island: one bath into which a stream of natural spring water flows from a rock waterfall with a view that looks about 20 meters down onto a small stream and vegetation.
Because it is just one bath it is mixed bathing, which means you need to wear swimming gear (there is a single changing room at the side of the bath). While it does feel a little strange bathing in swimming trunks, the design of the bath is beautiful and because of its slightly difficult to reach location you might be the only one there!
