Esashi Shiei Koeji Snow Forecast

Look at the most recent 12 hours, not the weekly total. The headline number only helps once you know whether cold air spilling over the Tohoku spine is the pattern to watch. With a 640 to 880 metre elevation band and 240 metres of vertical, the whole hill changes quickly because the elevation band is compact. A seasonal baseline around 5 metres means freshness and temperature matter more than chasing a big total. The swing variable is timing, because the compact footprint gets tracked or softened quickly. If you are looking beyond the ropes, only chase that angle when the forecast also shows settled wind and stable visibility. Chase a cold morning immediately after fresh snow; skip warm afternoons unless you are there for relaxed laps.
