天恵泉

Tenkei Hot Spring
Sampled at wellhead
湯
Simple

A strongly alkaline simple thermal water reaching pH 10.5 — high enough to give the slippery, soft feel of Japan's beauty-water family. It is only lightly mineralized at 181 mg/kg dissolved solids, but a generous ~80 mg/kg of metasilicic acid leaves the kind of thin silica film that makes skin feel noticeably smoother afterwards.

531. 天恵泉 白根桃源 天笑閣, Minami-Alps, Yamanashi ★ Onsen for 600. Operating hours are listed as 10:30 to 20:00 (closed Mon). They stamp the Yamanashi 100 Onsen book, but the stamp is badly worn. The staff emphasizes that each visitor gets their own clothing basket in front of the changing room, and they spray the baskets with disinfectant after every visitor. Bath photos are from the internet, match the real thing. Three wooden baths inside; there are traces of mold on the wood. Clear water, temperatures: 30, 40-41, 42-43. Breathing inside is good. Solid place, but inconvenient to get to. 11.05.2025
