Keirin onsen

94. Keirin Onsen, Beppu Onsen across from the stadium in Beppu. Price 110, the old lady stamps your passport. No soap/shampoo or shower, but inside it's fairly civilized. Apparently tattoos are fine — there was a fully tattooed guy and everyone reacted positively to him. Quite a few visitors. Water in the bath is hot, but before me guys were actively diluting it, and the source pipe pulls in scorching water. So I think the original water temperature would be extremely powerful.
