144. Ogurayakushi Onsen Okanoyu, Beppu ★ A no-frills onsen for ¥200. The stated hours are 06:00 to 22:00. It is not included in the Beppu onsen stamp rally, so they do not stamp the 88-onsen booklet. There is no staff, and no shower. There is no sign listing the water composition. The water is clear, and the temperature is 42.5. It is comfortable to breathe inside. A cozy, memorable onsen. Too bad it is not included in the onsen stamp rally. 03.05.2024 31.03.2026
