ski in Hakuba late April

I know it's late in the season, but can you recommend any resort in Hakuba region which will still have good snow conditions in late April this year for an advanced level skier? If a resort outside of Hakuba will be better, please suggest so, but don't say Hokkaido as I'm unable to go there on this trip.

Looking forward to your suggestions. I rarely get an opportunity to ski - so am desperate to find a place where I can find decent snow to ski.

I am afraid there is no good snow left in late April anywhere in Japan. Naturally, the higher you go, the better is the snow. The higher areas of Happo-one may still be tolerable:
