Check the freezing level against the full vertical first. The headline number only helps once you know whether cold air spilling over the Tohoku spine is the pattern to watch. With a 500 to 1328 metre elevation band and 828 metres of vertical, the trees and upper storm laps hold soft snow well after the open faces are worked. A seasonal baseline around 8 metres means small clean refills matter more than waiting for a giant number. The swing variable is wind: light flow lets the trees refill, while a hard blast strips the exposed entrances. If you are looking beyond the ropes, only chase that angle when the forecast also shows settled wind and stable visibility. Chase it when 5 to 15 cm lands overnight with light to moderate wind; if gusts climb, make it a sheltered-tree day.
