The spa was excellent! Great hot spring in the property! It is little bit tricky to have breakfast if you didn't reserve in advance. There were no buffet and reservatio only. So when I checked the available for next day, only 10:30am spot were available (I have golf tee time reservation at 9:30 on that day
The service during my stay in Hoshinoya was the best.
It was good time to fully enjoy nature during my stay. Thank you very much to all member of Hoshinoya.

Beautiful resort. So pretty during Autumn season. Come here to enjoy the scenery and slow things down. We really enjoyed the breakfast and onsen facility here. Love their afternoon tea and sake bar!
my husband and I celebrated our wedding anniversary at Hoshinoya Karuizawa. We had a wonderful stay. The onsen within the hotel was really good. Both of us enjoyed the facilities. We would like to especially thank the staff Miyu( dining),Saru, Takahashi(spa) and Leo san (front desk ) who took care of us during our stay .
Tranquil hotel with ample space for relaxation throughout the property. Free car service in and out, even has a kids playroom that helped to entertain my young 15mo while my husband and I took turns for onsen. Great service and also in room dining.
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!
The hotel facility is very old like last century. The bath was not maintained clean given the high hotel paid. Not much amenities can be used but the only thing is nature appreciation if you are in that category. Overall it’s not worth the money.
