Onsen black outline icon
Outline icon of an onsen hot spring: oval basin with three rising steam curls
About the Onsen black outline icon
A wide flattened oval stands for the pool of a Japanese hot spring, with three wavy steam trails curling upward from its surface — the map symbol used across Japan for onsen and sento bathhouses. It communicates bathing, hot water, relaxation and thermal spa culture. Use it in travel guides and maps of Japan, ryokan and hotel amenity lists, spa and wellness booking apps, bathhouse signage and restaurant or izakaya branding.
The steam lines are drawn as loose S-curves of differing heights so the group feels natural rather than mechanical, and they break the top of the oval to suggest rising heat. Pair it with towel, sauna, hot tub and thermometer icons for a wellness set. Give it a little top margin so the tallest curl is not clipped.
This is the black outline version of the onsen icon: even, monoline strokes that stay crisp at small sizes and suit clean, minimal interfaces, wireframes and light backgrounds.
