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 they do not share a joint lift ticket.
Last season two ski courses that have been closed since 2011 made a comeback - the Tochinoki and Mizunara courses in the upper back Nishiyama area of the resort. Mizunara is kept ungroomed. It was good to see them back.
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.
Ski and snowboard lessons are available at White World Oze Iwakura.
