The mountain's big with nice wide long runs. It's an hour away from Niseko, so it gets similar light dry fluffy powder, but without the crowds of powder hounds tracking everything in sight. Off piste mostly exit nicely back onto courses, Mt.Isola's an awesome wide open playground. We had crap snow the first two days, but the powder heaven on the last day made up for everything and more. The runs connect nicely so that getting back to the hotel (on the far west) from Mt.Isola (east side, with East Mt. inbetween) only takes like 10-15 min, great design.
Oh, and you can stuff yourself silly with all you can eat and drink Ghengis Khan (lamb yakiniku), in a hotel restaurant for 3000 yen.
From March, 2006
Snow condition on visit:
Slush => Crusty/Ice bahn => Knee deep powder
Things I liked:
Big, good snow, less tracked off piste than Niseko, well designed layout where most lifts go all the way to the top
