Moderately mineralized at roughly 1,195 mg/kg of dissolved solids, it bathes with noticeable body while staying gentle on the skin.

164. Shuhoukaku Kogetsu, Kawaguchiko ★★★ I stayed overnight. The hotel is on the north side of Lake Kawaguchiko, without a car it is not always convenient to get there. From a good room, there is a great view of Mt. Fuji through near-panoramic windows. The room air conditioning was set perfectly, it was always comfortable in terms of temperature, and there was no draft. The hotel also has its own sort of back yard, where you can go straight down to the lake to admire Mt. Fuji or even go fishing, I saw several different anglers there more than once. At the exit to the back yard there is a foot bath with a great view through the onsen water, which flows down a separate structure, so you get a nice image with Mt. Fuji reflected in the water. Dinner was an excellent kaiseki served in the room, they gave me a double portion as I asked for, I checked in alone, but the room is charged for at least two people. Breakfast was a simple buffet. The indoor bath has clear water, there is a bubble area, and the temperature is hot+. Breathing inside is tolerable. Good view of Mt. Fuji. The outdoor bath has a partial roof. The water is clear, and the temperature is hot. There is also a good view of Mt. Fuji. I really liked both the stay and the baths, a cool place. If you are there for the view of Mt. Fuji, it is definitely one of the top places. 07.07.2024 08.07.2024
