A very different experience for a foreigner, and one that I cherished as a student of Buddhism. If you aren’t adventurous, I don’t recommend it, and if you go, please be curious, open, and full of respect. The non-sleeping rooms will be very cold in winter, the food served is the food served, without changes available, there are rules about which slippers to wear where and what can be photographed, etc. If you’re interested in deep travel (versus hedonism), you will be gifted and changed. Otherwise, please don’t go.
The experience was what we expected. Very Japanese, quiet with beautiful gardens. They changed our booking from a room for 6 to three rooms for 2 each and had a nice garden view. The dinner was surprisingly very good with all vegetable dishes but quite diverse texture and taste. We enjoyed our stay.
