Onsen Pools

Originating from Japan, onsens are traditionally pools heated with geothermal hot springs, each offering health benefits derived from the minerals and elements present in the water. At WORLD SPA, the water in our onsens is simple salt water, but each pool offers differing, contrast temperatures: cold (52°F), warm (101°F) and hot (104°F).

How to use

We recommend cycling through the pools at your leisure to benefit from hot/cold contrast therapy. The cold onsen pool is particularly effective as a plunge pool after using one of our saunas. Please shower before entry and upon exiting the onsens.
