Forecast tips for Yachiho Kogen
Start with the upper-mountain wind and cloud line. The headline number only helps once you know whether a cold inland trough is the pattern to watch. With a 1630 to 1830 metre elevation band and 200 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.
