Thanks all for the help. I was watching for Yuzawa too however, on their main website it says opens 20th Dec 2014. Not too sure of Kagura, will definitely check it out.
As one (or many) have mentioned, details about snow season hasn't really been out there yet...so nothing much I can search for (Not knowing Japanese doesn't help either)
Hope to maybe get a few nights stay up there, not considering Hokkaido as flights be booked to Tokyo and want to stay away from the hassle to go another city (and not have time to explore) ...that will be for the next trip
