Skiing

Japan's environmental diversity is among the most distinct in the world. While it may be a nation of islands, many people may not know that a staggering 80% of Japan's landmass is comprised of mountain ranges. Such is the reason why Japan just so happens to be a diamond in the rough for ski and snowboard pros and enthusiasts worldwide. From as early as November in the north to as late as May, snow will envelop Japan's vast mountain ranges making one of over 500 ski courses (exceeding the number of courses in the US) a choice destination for those needing a bit of flexibility for their vacation plans.
