105. Kamiya Onsen, Beppu Grandpa onsen. No shower or soap/shampoo. Staff present. Entry costs 300, stamp available. The old lady inspected my passport stamps with interest and gave recommendations about neighboring onsens. Couldn't find a proper mineral composition chart. Inside there's one small bath, clear water, temperature is hot+.
