Went during a weekday and the runs were practically empty except for some school groups. I paid 8,500yen for a 2day mountain pass and 8,000yen for 2day snowboard hire. For the lift pass they use the electronic keycard system which requires a deposit.
For snowboarding the runs were good and included a bit of variety. But the closest slopes in this area are mainly catered for skiers and you have to walk to Kasadake to snowboard and the other snowboard runs
