Nozawa Onsen is a traditional Nagano village with 36 runs rising from 565 metres to 1,650 metres, a vertical of 1,085 metres, spanning a sizeable 297 hectares. The grading is 40% beginner, 30% intermediate and 30% advanced, with no expert-rated runs, so it works for a broad mix of skiers. Nineteen lifts, including two gondolas, five quad chairs and three surface lifts, serve three main base areas. The mountain is long and varied, with open cruising high up and steeper pitches that drop right toward the village. Few Japanese resorts pair ski terrain with onsen culture so closely.

The Yamabiko sector is the main intermediate zone, with five open courses labelled A to E and designated tree skiing beneath its quad chairs. The Skyline Course is an advanced run of about 4.5 kilometres that lets skiers return to the village from the top of the mountain, and the Nagasaka Gondola, opened in 2020, runs up to Uenotaira and the popular Paradise course. Beginners have gentle slopes in several sectors. Nozawa suits groups with a spread of abilities, powder chasers who respect the tree rules, and skiers who like finishing the day in an onsen. Weekends can be busy at the lower base.

The 2025-2026 season opened 3 December 2025 and closes 6 May 2026, spanning five months of operation. Typical seasons run late November through early May depending on early snowfall, with the high-elevation Yamabiko zone often skiing into Golden Week whilst lower slopes close in mid-April. Full resort operations establish by mid-December once base depths exceed 200 centimetres across all elevations.

Nozawa receives an average 10 metres of annual snowfall with base depths routinely reaching 4 to 5 metres by February. The second week of January averages 72 centimetres of snowfall across 5.6 snowy days, marking peak accumulation periods. North and northwest aspects on Yamabiko and Uenotaira preserve cold snow through March, whilst west-facing Skyline and lower runs soften earlier each afternoon. The resort operates without snowmaking except recent installations on Nagasaka beginner slopes.

January and February deliver the most reliable powder and coldest temperatures, with summit readings reaching minus 11 degrees during major storm cycles. December carries marginal coverage risk but rewards with empty slopes when snow arrives early. March sees spring consolidation with corn snow developing on sun-exposed aspects, though Yamabiko maintains winter conditions through month-end. Late April and early May offer slushy lower runs with firm morning corduroy higher up.

The Dosojin Fire Festival on 15 January attracts capacity crowds requiring advance bookings months prior. New Year's Eve extends night skiing until 2330 hours with fireworks and sake service on slope. Saturday night skiing operates from early January through March on the Nagasaka quad chair and 700-metre illuminated run. Resort hours run 0830 to 1630 daily, with night sessions 1700 to 2000 on Saturdays.
