A weakly alkaline simple thermal spring at a comfortable source temperature of 38.7 C. Total dissolved solids sit at a light 590 mg/kg, but metasilicic acid runs to 56 mg/kg, leaving the thin silica film that places this water squarely in Japan's beauty-water family. Radon at roughly 74 Bq/kg adds a quiet but real second dimension that the modest mineralization belies.

405. Hakata-yu, Futsukaichi Onsen, Fukuoka Onsen for ¥350-¥450, the website is very proud of its history, the business itself started in 1860, and Futsukaichi Onsen has a history of more than 1300 years. The stated opening hours are 10:00 to 21:30. They stamp the Kyushu 88 onsen stamp rally. The bath photo from the internet matches. I went on Sunday evening, there were a lot of people who wanted to use the onsen, so at reception they only offered to give me a ticket for an onsen visit in an hour, I replied by suggesting they give me one in three hours instead, so I could go have dinner at the ryokan first. The staff are young, but very pleasant and attentive, and they handle the visitor load well. Inside there is a bath with clear water, temperature 41-42. It is comfortable to breathe inside. 12.01.2025
