Jigokubaru Onsen

77. Jigokubaru Onsen, Beppu True old-school onsen. Non-members of the association/club are allowed from 10 to 17. 100 yen into a box, no shampoo or shower. Clear water in the bath, no notable smell, hot. Breathing in the bath is excellent — well ventilated. The mineral composition signs at the entrance and in the changing room differed — photographed both. Stamp available, but they give it at a shop a couple of houses away called Kotobukiya, which has an inconvenient schedule. I actually learned about this from a photo of a sign on Google Maps that someone posted 6 years ago (I couldn't find that sign during my visit).
