Travel south from Hokkaido to find Shiga Kogen, located in Nagano, hosting one of the largest ski and snowboard resorts in Japan. Many may recognize Nagano from the 1998 Winter Olympic Games, and for obvious reasons. Different types of terrain spread around several mountain ranges connect several different resorts together, all accessible using one lift pass. High snow quality, mesmerizing views, and a vast array of terrain all make Nagano one of the most ideal ski and snowboard destinations in the world.
