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 area has two bases: Lumiere by the upper car park and Core House 2in1 by the lower one. One lift ticket covers both this area and the neighbouring Shirakaba Kogen Kokusai ski area. A heliport sits beside the slopes. Sources: whitebirch.co.jp, town.tateshina.nagano.jp (sources read 12 Oct 2026; an AI draft the site operator has not yet checked)

85% of the vertical on the runs descends to the north or east. Those slopes get the least sun, so the snow lasts longer.
The most snow falls in March. March brings as much as January, or more. In amount, March brings 46 cm, about the same as the median of 46 cm.

These are analyses of hot spring sources, not a list of baths you can visit. They date from 1910 to 2005, many from decades ago, so today’s temperature and chemistry may differ. Names are as recorded in Japanese. Temperature and pH bands follow Japan’s standard for analysing hot springs.
