I went to Kannawa Hyotan Onsen by mistake during my tour of the Beppu Hells. Hot spring baths are everywhere in Beppu. Plumes of white smoke rise up in almost every direction. Even the cold water here comes out of the tap hot. So, at Kannawa Hyotan Onsen, it was no surprise to find a free outdoor foot onsen at the entrance. I decided to take off my shoes and socks and relax for a while before heading further uphill to the Beppu Hells.
