exactly.

as you mentioned we already have various methods to map bathing facilities,
thanks for pointing out leisure=public_bath.

So the idea is to have
natural=hot_spring - the hole in earth where hot water is comming out
+ natural=water - if there is a pool of water around it
+ water_characteristic - attached to both spring and water
+ all other related facilities mapped with their own well known tags such 
  as tourism=attraction, amenity=public_bath, leisure=beach_resort, 
  natural=beach, sport=swimming .. please add those which I have forgotten.

Some of those tags, like swimming need improvement which is independent from
this proposal.

water_characteristic is intended to be reusable for natural=spring and all
waterways and other water bodies.

natural=hot_spring is for springs of natural origin. A leisure=onsen is 
orthogonal to this so those could be easily combined if the onsen is from
a natural source. Otherwise you would have just leisure=onsen.
