Most accomodation is in great detached wooden cabins. Get a group together to cut the costs. The snow is usually fresh but is topped up by extensive snowmaking. The views of the sometimes-active volcano Mt Asano are highly photogenic.
Runs are a little on the short side, but the resort is almost deserted mid-week.
Rentals are available but are of a low standard. Try to get everything in Tokyo if possible. The latter taking a mere hour from central Tokyo. If you haven't got the time or the inclination to go further into the Japan alps, this is a great option. Comment on this review.
