A calcium-sodium sulfate-chloride spring blended from Fujikawaguchiko Town's No.2 and No.3 wells. The settled, mineral-rich sulfate body carries a salty edge from a chloride sub-type, neutral in pH and moderately mineralized with noticeable substance. With metasilicic acid around 60 mg/kg, it leaves a thin silica film that makes skin feel smoother.

About

The Kukuna sits right on the shore of Lake Kawaguchiko, and the baths make the most of that position: both the indoor large bath and the open-air rotenburo face Mt. Fuji across the water. The hotel has two gender-separated bath halls that swap in the middle of the night, each with its own sauna type. A private reserved bath, Lani Lanai, is also available. Select room types have a private water terrace with an in-room rotenburo.

193. Kukuna, Kawaguchiko ★★★ Stayed overnight. A hotel on Lake Kawaguchiko with views of Mount Fuji and an infinity onsen. A fusion of Japanese and Hawaiian themes in the decor, staff uniforms, and food. Dinner was a set meal plus a buffet. They honestly gave us a double set, since the room could only be paid for by two people, but it does not make much sense, because the set itself is not small. But there was a chef's plate with appetizers, and these were the most delicious appetizers I have ever had in my life. The rest was also on point, and you could fill up at the buffet. Breakfast was a fairly standard buffet. The room was very comfortable, with all the conveniences of the Western side, but with stylized tatami and sleeping on futons. I booked a massage, but it did not really work for me, it was average. There are two bath sets that alternate between men and women. Both sets have infinity baths with a view of Mount Fuji. On my days Fuji was not visible, so I added photos from the official site at the end, and based on my experience with these places, I am ready to conclude that they match. The evening and indoor bath sets are very similar to each other. The indoor bath differs in its construction. The outdoor baths also have small structural differences with the infinity view. Overall, it is great that they put in the effort and made the baths alternate between men and women. The water is clear, the indoor bath is hot, and the outdoor bath is between warm and hot. For 3000 I booked a private bath. Nothing unusual, a small bath with clear water and places to lie down, the water temperature was hot, maybe it had been diluted before I got there. There is a small balcony. A top place. An infinity onsen with a view of Lake Kawaguchiko and Mount Fuji. The fusion style is also done well. 15.07.2024 16.07.2024
