A calcium- and sodium-led sulfate spring with a salty chloride edge, giving the water a settled, mineral-rich body. It is neutral and hypotonic, yellow and clear at the source with a faintly metallic taste. With 52.8 mg/kg of metasilicic acid it leaves the kind of thin silica film that makes skin feel a little smoother afterwards.

189. Sunnide Resort Yamanashi, Kawaguchiko I stayed overnight, but without meals. It is on the north shore of Lake Kawaguchi. Booking was inconvenient, Japanican was glitchy, and on Rakuten I had to search manually. It is not very convenient to get there without a car. There should be good views of Mount Fuji, but during my stay it was not visible for most of the time. In the evening, already in the dark, fairly clear outlines of the mountain appeared, so I included a photo of Mount Fuji from the website, and I think the match can be confirmed. The ryokan itself is very tired in the bad sense of the word. There is no Showa vibe here, just everything inside the room is very heavily used, with scratches and scuffs. The onsen is in a separate building on the second floor. The water in all the baths is clear, and the temperature is between warm and hot. The indoor bath is supposed to have a view of Mount Fuji. The windows were constantly fogged up, and it was comfortable to breathe inside. Outside there is the main rectangular bath, there is one extra flow from below that periodically creates movement on the water surface. There should be a view of Mount Fuji from the bath. There is also an additional small octagonal bath, slightly set into a recess in the outdoor area. Given the deplorable condition of the room and the competition in Kawaguchiko among ryokan with a view of Mount Fuji, this ryokan falls far behind. 13.07.2024 14.07.2024
