Gion onsen

110. Gion Onsen, Beppu Grandpa onsen. No soap/shampoo or shower. Entry 100 yen into a slot in the table, but staff is present. Stamp available. Inside there's one oval bath, clear water, temperature is between warm and hot — possibly someone before me diluted it heavily (next to the main bath there's a washing hole with scorching water). Breathing is excellent.
