I can't say enough good things about Niseko United, and specifically the Annupuri side. I've been riding in Japan for three seasons and I've never experienced anything quite like this. We spent a half a day on the Grand Hirafu side and then went over to Annupuri and never looked back.
Grand Hirafu was slightly crowded; not terrible, for the time of year, but crowded nonetheless. Annupuri was basically empty. No wait time for the lifts, no congestion on the runs,
