Yunomaru Snow Forecast
Koyo season is doing the heavy lifting at Yunomaru. Morning frost is possible, but the mountain is still mostly in sightseeing mode. A dusting up high would be scenic, not a reason to book lift tickets. This is when anticipation starts to feel reasonable again. First flakes are not first chair.

Forecast tips for Yunomaru
Start with the upper-mountain wind and cloud line. When a cold inland trough is the pattern to watch, the live numbers usually matter most in the first lift window. With a 1730 to 1965 metre elevation band and 235 metres of vertical, the whole hill changes quickly because the elevation band is compact. A seasonal baseline around 4 metres means freshness and temperature matter more than chasing a big total. The swing variable is whether the upper lift can run with enough visibility to make the top worth using. If you are looking beyond the ropes, only chase that angle when the forecast also shows settled wind and stable visibility. Chase it after a cold storm only if the wind eases; if the top is socked in, wait for the next clear window.
