Japan, with its unique geography and climate, offers an exceptional experience for winter sports enthusiasts. Millions of years ago, the Japanese mountain range detached itself from the Asian mainland, forming the island nation we know today. Consequently, approximately 80% of the country is mountainous, providing a stunning backdrop for skiing and snowboarding.
Japan's mountainous terrain is ideal for winter sports.
The Legendary Snowfall
Japan's suitability for winter sports isn't solely due to its geography. Abundant snowfall is a key factor. Cold air masses from Siberia gather significant moisture as they travel from the mainland over the sea, which then precipitates as snow over the Japanese mountains. This phenomenon is particularly pronounced on the northern island, where the snow is remarkably dry and even has a distinctive name: "Sushi Powder."
In the renowned Niseko ski resort, an astounding more than 15 meters of this special snow falls every season!
"Sushi Powder" - the dry, deep snow that makes Japanese skiing legendary.

Olympic Legacy and World-Class Resorts
Internationally, the ski resorts that hosted the Olympic Games are best known. Sapporo hosted the Winter Olympics in 1972, followed by Nagano 26 years later in 1998. World Cup races have also been held in Naeba and Morioka, further cementing Japan's status as a premier winter sports destination.
Nozawa Onsen: A Month-by-Month Guide
After nearly 30 seasons in Nozawa Onsen, we have a pretty good idea of what to expect month by month. Of course, Mother Nature is unpredictable, so conditions can vary from year to year.
When is the best time to ski Japan?
The ski season here usually starts in December, and if we’re lucky, sometimes even as early as late November. As a general rule, from around December 10th onwards, you can usually expect enough snow to play in, ride a sled, and often even ski.
January: In recent years, we’ve seen over 100cm of snow in a single night around mid-January, with frequent 50cm dumps as well.
February: February usually continues January’s heavy snowfall, with a deep base and plenty of powder days.

March: March is a surprise month and probably my favorite. The best part? For some reason, people tend to think winter is over in March, but that’s definitely not the case in Nozawa. It’s the perfect time to switch on and head up here.
April: April officially marks the start of spring skiing. But with a 1,000m vertical difference between the top and bottom of Nozawa Onsen, the upper slopes-right off the gondola-often remain a perfect winter wonderland. Towards the end of the month, you can even enjoy some warm, sunny days where skiing in a T-shirt is totally possible-an awesome feeling!
Nozawa Onsen Ski Resort usually stays open until around May 10th, celebrating the long Golden Week holiday in style. Up top, spring skiing conditions are typically slushy and fun, though I’ve even seen snow in May some years. After May 10th, everyone breathes a sigh of relief as the farmers take over the slopes.
Nozawa Onsen offers excellent snow conditions throughout the season.
