Start with the overnight low and the next snowfall window. Here, cold air spilling over the Tohoku spine is the pattern to watch, so the useful question is how cold and calm the next window stays. With a 680 to 1213 metre elevation band and 533 metres of vertical, the gladed pockets are the first place to check once the groomers get tracked. A seasonal baseline around 8 metres means small clean refills matter more than waiting for a giant number. The swing variable is ridge wind, which can turn a promising number into a thinner, scoured morning. If you are looking beyond the ropes, only chase that angle when the forecast also shows settled wind and stable visibility. Chase the first half of the day after a cold refill; skip if the forecast warms before lunch.
