I was always knew this was going to be a true Buddhist experience, but was pleasantly surprised by the comfort and added amenities offered by Kumagai-Ji.
We went for the traditional room, with tatami mats and sliding paper doors, and were blown away by the size of the room (actually two rooms side by side that we both had) and the beauty of the place and location to the zen garden. There was a table for which you kneel at, but had an under heater for your knees! The room was opposite the garden, and while you are eating dinner, they arrange the bed for you which was like a thick puffy cover, rather than a mattress, but was weirdly comfortable and very warm.
The dinner and breakfast were true vegan Buddhist food, and I'm not gonna lie, would definitely take some getting used to. Overall, fantastic though. To experience that kind of food in a place like that, was truly special.
We also got to experience the morning ceremony and fire ceremony, which were fantastic and included in the price.
Now I haven't mentioned the best part yet, and that was the staff! Our host, a very nice lady that we unfortunately never got the name of, had the best English of anyone we had met in the whole of Japan! She was extremely helpful, showed us around everywhere and had a great sense of humour. The monks that also helped out, although didn't speak much or any English, were always ready to help and very kind.
Overall, this is a must stay for koya-san, and can't recommend it enough!
