I had read a few things about Kawaba - some people had noted how it was larger than they imagined, and for some reason I kind of ended up feeling that too. Nice long lifts and if you keep to the quads, fast too. It's a bit out of the way - well, 25 mins from Numata IC - but still pretty popular. And I can see why. Being high up, the snow quality was really good and... well, that's enough for me to recommend a place! Enjoyed the courses too. And my friend said the park was pretty good. Get some Mister Donuts on the way back to the IC. Recommended.
PS The place closes at the end of the day, so there's no apres-ski going on nearby.
