White World Oze Iwakura is located in Katashina village in Gunma Prefecture. It is located on the south-eastern slopes of Mt Nishi, to the east of Mt Hotaka. The resort first opened in 1974 and the Gondola was added in 1989. White World Oze Iwakura is very close to Katashina Kogen resort, but the two are not physically connected and do not share a joint lift ticket.

From the 2017-2018 season, a new automated lift ticket gate system has been introduced at White World Oze Iwakura.

The region to the east of Minakami town and to the north east of Numata city in northern Gunma Prefecture is made up of Kawaba village and Katashina village. There are a number of ski and snowboard resorts dotted around the mountains of this region, all of which are accessed off the main Route 120 road from central Numata. This road is otherwise known as the Nihon Romantic Highway and continues through to Nikko in Tochigi Prefecture, though the prefecture border section of the road is closed during the winter months.

Gunma Prefecture is located in the north west area of Kanto region on the main island of Honshu and shares borders with Niigata Prefecture to the north and Nagano Prefecture to the west. There are over 20 ski and snowboard resorts in Gunma Prefecture and they are mainly concentrated in the northern regions of Minakami and Katashina and the western region of the Prefecture.

As the 2018-2019 winter season approaches, we are gradually updating the information on these pages (for every ski resort in Japan).

Many ski resorts in Japan do not update their own information until late autumn. Our process of updating information will be ongoing right through until the end of November. In the meantime, ski resorts usually open and close around the same dates each year - so even if the planned season dates shown on this page are still from the 18-18 season, they can be used as a good indication of the upcoming season.
