Stay at Oze Iwakura Resort Hotel and hit the slopes
Located 2 hours by car from Tokyo, White World Oze Iwakura in Gunma Prefecture is one of the best in the Kanto area in terms of size and snow quality. The vast slopes include steep slopes with an average gradient of 40 degrees for super experts, long cruises with spectacular views of the varied terrain, and beautiful groomed runs that will make you speed up without even realizing it. Then suddenly, a mogul slope perfect for practicing your snow skills and a wide run that is great for carving appear. There are also six ungroomed runs where you can enjoy deep powder after snowfall, and the Nishiyama slope behind the main slope is especially popular with snowboarders. Nishiyama, located on the northern slope of the mountain, has the highest quality powder snow in Iwakura. This area is relatively empty, so the competition for powder snow is not that high, making it a great spot to aim for when it snows. Despite the wide variety of courses, surprisingly, seven of the 6 courses are over 16 km long, and all of them are very challenging. It is also convenient to have a gondola for efficient operation. It is the largest slope in the Kanto region, and it is so large that you cannot ski on it all in one day.
This winter, Oze Iwakura Resort Hotel, located at the entrance to the slopes, will celebrate its 40th anniversary and reopen its lounge area on the first floor. There will be a kids' space, which is great for families, a free drink bar including alcohol, and a book lounge, all of which are available to guests free of charge. Having a place to relax when the weather gets bad or the kids get bored will undoubtedly make the place even more comfortable. Day visitors can also use the facility for a fee, which includes a hot spring bath, but since the hotel is located right in front of the slopes, there are also great benefits to staying overnight, as you can prepare yourself in good condition and take it easy if you're aiming for night skiing or early morning powder. If you're planning a trip to Iwakura this winter, why not consider a two-day, one-night plan?
