A sodium chloride strong-salt spring with dissolved solids of 25.5 g/kg — richly mineralized water that leaves a noticeable salt film on the skin. Weakly alkaline and hypertonic, it runs colorless and clear at the source with a slightly salty, faintly metallic tang. The chloride character makes it strongly heat-retaining, so warmth lingers well after the bath.

584. 尾白の湯, Hokuto, Yamanashi ★★ Onsen for 830 yen (410 for locals). Operating hours from 11:00 to 21:00 (closed Wed). They stamp a different stamp in the Yamanashi 100 Onsen book. Bath photos from the internet match reality. 1. Outdoor bath area. No view, but spacious and cozy. 1.1. Large stone bath, clear water, temperature around 40°C. 1.2. Small stone bath, murky brown water, temperature around 38°C. 2. Indoor area. Noticeable chlorine smell. Breathing inside is fine. 2.1. Large bath with a round bubble zone. Clear water, temperature around 41°C. 2.2. Reclining zone. 2.3. Bath with two jet sets and utaseyu. Clear water, temperature around 38°C. 2.4. Sauna. 2.5. Cold bath. The rotenburo area and the brown water — rare for Yamanashi — make this recommended for a visit. 15.05.2025
