Nozawa Onsen is in pre-winter waiting mode. Trail conditions, visibility and cold mornings matter more than accumulation. A cold snap could whiten the tops, but it will not change the travel plan yet. Pack for cold mornings and wet trails rather than chairlift laps.

Nozawa Onsen is outside its usual snow season right now.
A typical season here runs November to March, peaking in January, with around 11m of snow in total.
That makes Nozawa Onsen the 10th snowiest of 31 Nagano resorts we have reviewed.
Estimated cumulative fresh snowfall at major on-mountain ski areas; actual totals vary substantially by resort, elevation, measurement location, and season.
Read the freezing level before anything else here. With more than a kilometre of vertical between village and summit, the live forecast can show one temperature for the resort while the actual conditions split in two: cold dry sea-effect snow up top, slushy refrozen ruts on the lower runs. That makes this one of the few places where a marginal-looking storm can still be a great day, as long as you stay above the mid-station gondola. If the forecast shows zero or below at the base for the whole cycle, that is a full top-to-bottom day worth booking around.
