Lift passes are cheap in Hakuba but here is a way to get them even cheaper. Print out the following vouchers for some great mountain deals.
Happo 1 adult/one child, 1 adult/two children
Happo 2 adults/one child, 2 adults/two children
Cortina: (there is also a regular lift and pizza deal at Cortina, which I think is 3700 yen. The coupon is not valid for both Cortina & Norikura.
Iwatake Family Pack A&B (1 adult, 1 child) & (1 adult, 2 children)
Iwatake Family Pack C&D (2 adults, 1 child) & (2 adults, 2 children)
Norikura 4 person pack
Thanks Sandy from Tokyo Shopping Tours for putting all the information together.
