An intrinsic part of both Japanese culture, as well as spiritual thinking, hot springs or 'onsen' are much more than just a hot bath. With more natural geothermal sources than any other country, Japan houses over 2,300 hot spring facilities up and down its archipelago, often clustered together in hot spring villages, like Kurokawa Onsen or Ginzan Onsen (the clue is in the name!).
