A simple thermal spring in Misaka-cho, Fuefuki city. Strongly alkaline at pH 9.34 — slippery on the skin and sitting squarely in Japan's beauty-water family. Lightly mineralized (720 mg/kg dissolved solids), so the chemistry is gentle on the body; the wellhead runs hot at 51.8 °C and is pumped to surface.

552. みさかの湯, Fuefuki, Yamanashi Onsen for 530. Surrounded by a rose garden. Operating hours are listed as 10:00 to 22:00 (closed Tue). They stamp the Yamanashi 100 Onsen book. Bath photos are from the internet, roughly match — I visited in the evening and decent bath photos for this onsen are scarce online. Indoor area. Breathing inside is fine. 1.1. Bath with clear water, temperature around 42-43. 1.2. Bath with clear water, temperature around 37-38. 1.3. Two utaseyu. 1.4. Sauna. 1.5. Cold bath. 2. Outdoor bath with clear water, temperature around 41. No view, everything behind a fence. 12.05.2025
