I love hot springs (“onsen” in Japanese). I might even consider visiting onsens a hobby of mine. Yet for some reason I completely forgot that I went to this weird (in a good way) amusement park onsen in Hakone, Japan. In addition to your standard Japanese hot spring, they also had a coffee onsen, a green tea onsen, and a wine onsen. I don’t recommend drinking any of it, but as a bath it was pretty awesome to experience. Japan definitely embraces its onsen culture.
