We had a very pleasant and comfortable experience during our stay and it was very worthwhile. We arrived later than what was planned but they still prepared the dinner for us. You will need to call them before 8pm though if you are going to be late. It might be difficult to find the place without a map or google maps in the dark. They also brought us to the Fuji Hakkei to take photos of the Mount Fuji with the Yamanakako lake. They also gave us some brochures of the nearby tourist attractions.
They also showed us around the facilities. The room was very spacious for the three of us and the room amenities were sufficient. They are also warm and friendly and showed us around the facilities. The dinner and breakfast have many dishes and are very filling. The sashimi was very fresh and do not have any foul taste at all. The place itself is actually quite accessible with the highway bus from Tokyo and you can also reach Sengen Shrine and Kawaguchi station with 1 bus.
