Why Visit Oze Iwakura Ski Resort in Gunma?

Top Reasons to Ski Oze Iwakura

Great Powder with No Crowds
Unlike more famous ski resorts in Japan, Oze Iwakura remains off the radar for most international tourists. Even on weekends, the powder stays untouched thanks to mostly on-piste local riders.
Ideal Off-Piste Terrain
This resort offers easily accessible tree runs and sidecountry skiing. The natural bowl layout means short hikes and easy returns to the lifts ? perfect for powder chasers and backcountry enthusiasts.
Dry, Light Snow
Being further inland, Oze Iwakura doesn’t get as much snowfall as resorts in Niigata or Nagano, but the snow is incredibly dry ? perfect for deep, floaty powder turns.
Variety of Terrain
With 18 ski runs, 10 lifts (including a gondola), and 697 meters of vertical drop (1,006m?1,703m), the resort has something for everyone ? from mellow beginner slopes to steep advanced runs hitting 40°.
Uncrowded Midweek Skiing
Visit midweek and you may have entire runs to yourself ? ideal for intermediate skiers looking to cruise groomers or advanced riders searching for fresh lines.
Nearby Ski Resorts
You can also ski nearby resorts like Kawaba, Oze Tokura, and Ogna Hotaka, all within easy reach for a multi-resort Japan ski trip.

Things to Consider

Not for Terrain Park Riders
Freestyle skiers and snowboarders may want to look elsewhere ? this is a powder and carving mountain, not a park destination.
Quiet Apres Scene
Katashina Village is peaceful and relaxing, but nightlife is minimal. Think onsen, not izakaya hopping.

Advanced: 5 black runs, including a 40-degree slope. Some are groomed, others left with natural moguls.
Off-Piste & Sidecountry: The resort’s highlight. Ski among birch and pine trees, drop into powder bowls, and return easily to the lifts.
