Katashina Village Oze Iwakura Ski Resort: Gunma's Largest Slopes

With a vertical drop of about 800 meters, diverse terrain, and excellent snow quality, Oze Iwakura Ski Resort in Katashina Village, Gunma Prefecture, is one of the largest and most serious ski resorts in the Kanto region. With runs suited to everyone from beginners to advanced skiers, and the abundant snow conditions of the foothills of Oze, this is the resort that skiers and snowboarders across Kanto dream about.

Highlights

Oze Iwakura Ski Resort is located in Katashina Village at the foot of the Oze wetlands in northeastern Gunma Prefecture. As one of the largest full-scale resorts in the Kanto region, it has long been loved by many skiers and snowboarders. Its vertical drop reaches about 800 meters, and the long run from summit to base is exhilarating. Its greatest appeal is its rich variety of courses, from gentle, wide beginner runs through moderately pitched intermediate courses to steep slopes that impress advanced skiers, so there is terrain to match every level. The steep slope, which also hosts giant slalom competitions, is especially popular with confident expert skiers.

Enjoying the Seasons

The ski season typically runs from around December to late March or early April. Midwinter, when the high-quality snow has piled up, is the best season. Oze Iwakura's fine snow owes to its location at the foot of Oze. Known as a heavy-snowfall area, the region gathers deep, fluffy powder that makes for exceptional skiing. The resort is well equipped with restaurants, rental facilities, and ski schools for beginners, so first-timers and families can spend the day with peace of mind. After the snow melts, from summer into autumn, hiking the Oze marshlands above is popular, making Katashina Village an area to enjoy nature year-round.

Practical Travel Notes

If driving to Katashina Village in winter, winter tires or tire chains are essential against frozen and snow-covered roads. The slopes sit at high elevation where weather changes quickly, so prepare warm, waterproof wear along with goggles and gloves. Lifts get crowded on weekends, holidays, and the New Year period, so a quieter weekday visit is ideal. Guesthouses and lodges in Katashina Village are convenient for overnight stays, but they fill up quickly on weekends, so book early. Which courses are skiable and operating status can change at the start of the season or in rough weather, so checking official information is recommended.

A Word of Advice

Oze Iwakura's great appeal is that a single resort covers everything from beginner practice to expert long runs. First head up to the summit and enjoy an exhilarating long run that makes the most of the vertical drop. Warm up your chilled body afterward at a hot spring in Katashina or the surrounding area. Combining skiing with a hot-spring soak is the tabitabi JAPAN editorial team's recommended way to spend a winter day in Katashina.
