An alkaline simple sulfur spring carrying the faint rotten-egg note of hydrogen sulfide. The pH is strongly alkaline, giving the slippery, soft-on-the-skin feel of Japan's beauty-water family. Lightly mineralized and gentle on the body, it makes for a mild, easy soak rather than a heavy mineral bath.

396. Kouraku no Yu, Asakura, Fukuoka I went for a day-use visit for ¥800, but outside the stamp rally it costs ¥1000. Day-use hours are listed as 06:30 to 10:00 and 13:00 to 23:00, and the rotenburo on the 4th floor is only available from the second time slot, they would not let people in there before 10:00. They stamp the Kyushu 88 Onsen stamp rally. The bath photo from the internet matches. Indoor bath. It is stuffy and hot inside. 1. Bath with clear water, temperature 43-44. 2. Bath with clear slightly yellowish water, temperature 40. 3. Sauna. 4. Cold bath. Without the rotenburo, this one can definitely be skipped if you are not collecting achievements. 12.01.2025
