Start with overnight snowfall and wind direction. When cold air spilling over the Tohoku spine is the pattern to watch, the live numbers usually matter most in the first lift window. With a 580 to 1130 metre elevation band and 550 metres of vertical, the sheltered trees make modest reloads feel deeper than the raw number. 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. With patrol boundaries in play, focus on how the inbounds snow will hold through the first half of the day. Chase it when 5 to 15 cm lands overnight with light to moderate wind; if gusts climb, make it a sheltered-tree day.
