Zao Onsen is a long way from boot-deep anything. The runs are grass, the trees are green, and the snowpack is a memory. Snow totals can safely be rounded to no. Heat, rain and visibility matter more than snow depth this week.
Check the freezing level against the full vertical first. Here, west to northwest flow off the Sea of Japan is the pattern to watch, so the useful question is how cold and calm the next window stays. With a 780 to 1661 metre elevation band and 881 metres of vertical, the trees and upper storm laps hold soft snow well after the open faces are worked. A seasonal baseline around 12 metres means moderate-looking totals can still refresh the main lines quickly. The swing variable is wind: light flow lets the trees refill, while a hard blast strips the exposed entrances. With patrol boundaries in play, focus on how the inbounds snow will hold through the first half of the day. Chase it when 10 to 20 cm lands overnight with light to moderate wind; if gusts climb, make it a sheltered-tree day.
