About

The baths here lean into a lava theme, with the indoor tubs and two open-air pools all styled around the volcanic landscape. On a clear day the rotenburo (open-air baths) look straight toward Mt. Fuji. The facility also claims Japan's first microbubble open-air bath. A sauna and cold bath round things out. The whole place has a compact, Showa-era feel, and the early morning session is popular with people coming off a night climb up the mountain.

162. Fuji-sensui, Yamanashi Onsen. Admission costs 800 yen, and a towel set costs 300 yen. I only found signs like the ones in the photo. It is not included in the Yamanashi stamp-rally. 1. Indoor area. It is comfortable to breathe inside. You can see a little of Fuji from the edge of the indoor bath. 1.1. First bath. The water is clear, and the temperature is between warm and hot. There is a slight smell of chlorine. 1.2. Second bath. Basically the same as the first one, but the water temperature is a little higher. 1.3. Sauna. 1.4. Cold bath. 2. Outdoor area. You cannot see Fuji from the bath itself, but you can see it while standing, especially from the edge of the area. Still, the view is not very interesting, because the fence and the leaves of the trees in summer block a lot of it. 2.1. Stone bath. The water is clear, and the temperature is between warm and hot. For summer, it is probably ideal. 2.2. Barrel for two people. 2.3. Chairs. I have mixed impressions, because the view of Fuji has some caveats, and there were a lot of local people on Sunday. 07.07.2024
