Oze-Iwakura great value ski in/ski out in Gunma


Oze-Iwakura, or White World Oze-Iwakura to give it the full title, is an excellent medium size Gunma Prefecture ski resort still virtually unknown to western visitors. It offers great snow and great value, with a choice of a 3-4 star hotel or budget hotel at the base. You can book a 3 night inclusive package from $AUD 1130 or as many nights as you want with Japan Holidays.

powder skiing Oze-Iwakura Gunma
Oze-Iwakura has some nice powder lines

Gunma has remained relatively off the radar for foreigners compared to the now hugely popular Nagano and Niigata Prefecture resorts like Hakuba, Nozawa Onsen, Myoko, Naeba-Kagura and Shiga Kogen. 

So you can still get a lot of powder lines with less competition for them here, especially midweeks. Tenjindeira near Minakami is getting better known, but the Katashina Village area is a bit further off the shinkansen and freeway routes.

Size-wise Oze-Iwakura is more like Madarao, a smaller area that exploded in popularity thanks to a pro-active tree course and powder policy.

If the same happened here a similar effect would likely follow, because there are a decent amount of tree lines and powder courses at gradients up to 40° on the marked runs.

Oze-Iwakura gondola
The Oze-Iwakura gondola accesses nearly the full vertical

The healthy vertical drop of just under 700m from the top back to the hotels at the base is served by the usual Japanese mix of fast and slow lifts. The gondola is the best of them, accessing nearly the whole vertical and most of the terrain.

Further over the back side you need to ride successive pair lifts to ski the black runs and trees on offer there – slow, but worth it, especially lapping here on pow days.

Oze-Iwakura offers 18 courses for all levels

With a top altitude of 1700m snow quality is usually good, and from late December to late March there’s usually a decent base.

Long groomers over 3km long keep intermediates and cruisers happy.

Off most lifts there are easier options so groups of different standards can hook up at the bottom and keep skiing together.

Oze-Iwakura also boasts easy night skiing of the base quad chair.
