An alkaline simple sulfur spring. With pH 9.67 to 9.9, it is strongly alkaline and delivers a remarkable slippery feel, placing it squarely in the Japanese beauty-water family. A faint sulfur taste and unmistakable rotten-egg note come through on entry, from dissolved hydrosulfide and thiosulfate ions. Mineralization is light at 579 mg/kg, so the body of the water stays gentle even as the sulfur character holds its own.

278. Sanogawa Onsen, Yamanashi ★ We went for a day trip bath for 650. It is listed as 8:30 to 19:30, last entry at 18:30, except on the second and fourth Tuesday of the month. It is near the border of Yamanashi and Shizuoka, with a countryside feel. They stamp the Yamanashi 100 onsen stamp book. Judging from the photocopy, the onsen was in the manga Yuru Camp. There are also newspaper clippings about this place on display. The bath photos online match. In the morning there were quite a few visitors and many local old men, who immediately took an interest in us. One old man told us he comes here from Shizuoka because this is a great onsen. The old men at reception told the owner that we were from Russia, and he got very lively and started talking about relatives, who is married to someone from Russia. Inside there are two baths with clear water, and it is comfortable to breathe inside. One bath has water at about 40 degrees, the other is around 30. There is a glass there so you can drink the water. The outdoor area has two stone baths. The water is clear, with a little lime. In terms of temperature, one bath is about 30 degrees, the other is a little warmer. It is inconvenient and far to get here, but the place is pleasant, and clearly popular with locals. 13.11.2024
