Beautiful property, wonderful public onsen, and excellent restaurant. Very peaceful location. While I loved my room (which was high up and overlooked the forest), it involved climbing some very steep stairs. Travelers with mobility issues should be careful about which rooms they reserve. I stayed two nights and wish that I had stayed three.

HOSHINOYA resort is a great place for relaxation. The environment filled with natural forest and maple trees. The service was exceptional. However, there were mosquitoes problem possibly harvested by the pond in the property. Hopefully the hotel can find solution to help with this problem. Otherwise, this resort is beautiful, quiet, and comfortable.

The water side room is spacious and the balcony is nice, you can see and listen the stream running and ducks swimming along. However, some rooms are near the walkway and you can see people walking along the stream, (I.e. they can see you as well) and gardener would be working in the morning which produces some noises. Staff are helpful and getting a taxi to stroll around for sightseeing is easy. You can either call the hotel car to travel around the hotel district or just on foot. The area is best for avoiding heat from summer.

What a peaceful place...you don't have TV and cables here. It has a bueatiful garden with multiple ponds. The bath facility is so so. Do not expect too much. This is the place for meditation and not-think-anything. The room price is going up too much if you not reserve earlier than you expect.

The view is excellent, service is good, meals are yammy, every thing is attractive for next stay. Except a stuff in the front desk is not friendly to new visitor. She missed my booking and ask to contact with Hotel.com strongly at that time even I show her Hote.com confirmation letter and would like to pay for a new room till her college found my reservation. It's great that I got my room after 30 minutes in communication with her. Otherwise, I cannot image heavy snowing and darker outside without a room for stay. It's my first visit Karuizawa and first time to Hoshinoya Karuizawa. Amazing front dest service!

This was one of the more memorable experiences and stays I've ever had - the loveliest even. Everything from the decor to the hospitality of the entire staff to the food to the meditation bath was a testament to intentionality. The attention to detail and storytelling of the omakase dinner at the restaurant was my absolute favorite part of our entire stay. Can't wait to return, hopefully for many years to come!
