Hanazono has got 3 chairs. Chair 1 you can access Strawberry Fields and Blueberry Fields, which have good tree runs. Chair 3 has got good tree runs off it too. Or you can ski the pistes. There is very easy access from Hirafu. You can just ski across or catch the shuttle bus.
There are good restaurants at the bottom, ski school and Hanazono Powder Guides.
It would be best to get an all mountain pass for the whole Niseko
