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 was introduced at White World Oze Iwakura, but there is more exciting news for 2018-2019 - two courses that have been closed since 2011 are making a comeback! The Tochinoki and Mizunara courses in the back Nishiyama area are re-opening for 2018-2019. Mizunara will remain an ungroomed course. It’s great to see them back.
