The five add up to the 100-point Powder Score: more fresh snow, more on the way and colder air all push it up. How we measure
The eight-seat Nikko Shirane ropeway climbs to the top station, and a run of about 4 km leads all the way back to the base. The upper floor of the Center Station at the bottom is Zazen Onsen, a day-use hot spring. Sources: marunuma.jp (sources read 13 Oct 2026; reviewed by the editor)
