Hayashida Onsen Yu No Yama No Yu

401. Hayashida Onsen Yunoyama-no-Yu, Asakura, Fukuoka Onsen for 600. Operating hours stated as 13:00 to 20:00 (closed Thursdays). They stamp the 88 Onsen of Kyushu book. The main highlight of this onsen is the many Showa-era artifacts — there's even a mini room dedicated to them. Inside there's a bath with clear water, temperature 39. Outdoor bath with carbonated clear water, temperature 35.5. The place is interesting not so much for the onsen itself but for the Showa-era artifacts and decor. If that's your thing, it's highly recommended — otherwise you can skip it.
