First post and intermediate rider, but I second Nozawa for spring snow. It always dumps a ton throughout the season and it shouldn't be too packed or crowded come March. Hakuba does have quite a bit more in terms of atmosphere and variable mountain terrain, though as previously stated, the snow might not be as good as you're looking for. Haven't been as far north as Hokkaido so I can't comment on that.
