I love Kawaba for many reasons. First, it's really close from where I live, I can get there in 1 hour. Then, there are plenty of areas to go to in the trees and the good things is, you can (almost) never get lost as there is only one way to the valley.
I went there on icy conditions also and I would not recommend it as it limits considerably the potential of the resort. The park is for beginners/intermediates but lacks big kickers.
The black and red slopes are pretty much empty as 80% of the people rides on the main green courses.
Resort very easily affected by wind.
No specific date.
Snow condition on visit:
Go there after it snowed!
Things I liked:
1st resort on the Kanetsu to go to, a lot of backcountry
Things I didn't like:
Crowded at times, kind of small if we stay only on slopes
