Niseko may be the most famous ski resort in Japan. Located 100 km south of Sapporo on the Island of Hokkaido, Niseko is comprised of 4 resorts located on one mountain. You are likely to run into more Australians here than Japanese. Seasonal winds from the Eurasian continent pick up moisture over the Sea of Japan and drop lots of powder on this area of Japan; the snow is considered some of driest, lightest powder in the world. It is particularly dry at Niseko because the volcano, Mt. Yotei, which is just to the east of Niseko, pushes the weather systems flowing west to east over Niseko back over the ski resort
