Start with the upper-mountain wind and cloud line. Here, Sea of Japan storm flow is the pattern to watch, so the useful question is how cold and calm the next window stays. With a 620 to 1845 metre elevation band and 1225 metres of vertical, the trees and upper storm laps hold soft snow well after the open faces are worked. A seasonal baseline around 11 metres means moderate-looking totals can still refresh the main lines quickly. The swing variable is whether the upper lift can run with enough visibility to make the top worth using. If gates are part of the day, treat wind and visibility as decision-making numbers, not small print. Chase it when 10 to 20 cm lands overnight with light to moderate wind; if gusts climb, make it a sheltered-tree day.
