Pros - Nice Cabin, nice location, vehicle comes with cabin.
Cons - Not able to stay in cabin for the whole booking, was not notified until arrival.
We arrived at the Chitose airport, where Yoshi met us. On the way to Niseko, he told us we would not be staying in our reserved cabin the first night because the "cleaning people still had the key." We stayed in a un-heated apartment in Kutchan the first night. After skiing the next day we moved to the cabin where we had to move out the previous renters luggage. Apparently, our place was double-booked and Yoshi lied to us so he could collect double rent for the overlapping day.
While the rest of our stay at the cabin was pleasant–nice quiet location just outside of Hirafu village (walking distance), van for 5 people (with ski racks), kitchen (small single electric stove burner, microwave, refrigerator) shower, washing machine, nice beds, drying racks for gear. The risk of actually getting the cabin might be the biggest concern when reserving this place. Other reviewers said they we put up in a completely different place for their entire stay. Renter beware when booking, maybe you'll get the cabin, maybe you'll show up and stay somewhere else. If you get it, you'll have a nice time.
