Nowaza onesen Tokyo and Kyoto

Hi there
We are booked to ski Nowaza Onesen 2-10 Jan.
This is our first time to Japan. We have a 12 and 14 year old.
We were going to come to Tokyo 29 dec before skiing but have been discouraged by friends as many tours etc are shut down over New Years. It also seems really expensive for accommodation.
So other option is to visit Tokyo after skiing. We are really keen to see Kyoto also but I am really confused at how to include Kyoto with having to lug ski gear etc. we could only allow 5 days. Would we go Nowaza onesen, Kyoto, Tokyo?

Or if we did arrive 29 Dec, would you suggest Tokyo or Kyoto first?
I am trying to be as cost effective. Thank you!
