Looking for an Appt or bedroom for a few month

Hi! I'm a freelance software engineer currently working in Tokyo but want to spend the snowboard season in Niseko (end of november to end of march). I need at least a room (if possible not too far from the slopes!) for myself with a desk and decent internet so I can continue to work from there while enjoying the powder! My Japanese is decent (maybe about N3 level?). I am looking for any solutions you could give me. I have a lot of things in Tokyo and moving in an empty apartment is also possible! Can be emailed to bolbovic at gmailcom. Can't wait to ride again!
