Uses natural hot spring water
273. Kuchisakamoto Hot-spring Baths, Shizuoka Public onsen in a remote area for 300, listed hours 9:30–16:00, except Wed. They stamp the 60+6 Onsen of Shizuoka 24/25 booklet. Marked with a special note in the stamp rally brochure. Part of some local stamp rally. Online photos match. Outdoor bath with clear water with fine lime deposits, temperature 39. Indoor bath with clear water, temperature 40. The place itself is pleasant, but the remoteness is uncomfortable, and it's not really worth going there just for this onsen.
