Was just in Niseko about a month ago. Stayed @ the Grand Hirafu Tei Hotel... OnSen was awesome! Snowed so much on the first two days we couldn't even off piste. Hiking wasn't allowed due to high avalanche warnings... Day 3... Sunny and POWDER!!! Avalung, Check. Hydration Pack, Check. Beacon, Check. Walkies, Check. Hike to the peak for some devirgination of the 90cm powder that came down the first two days, 5 min hike and a 5 min traverse around the top of the mountain to the bowl at the back... and more fresh powder. Got tired, Striped down, and sat in the onsen for 30 mins lookin @ the mountain. Geared back up, went for some more powder. Day 4, more snow... More searches for fresh powder, Day 5... Snowed another 30cm... Love it!
