Leap off a ski jump into the freezing air and land like a pro—or not. In this museum at the base of the Olympic Okura Jump, a realistic simulator lets you comparing jump distances. The 1972 Winter Olympics and other Japanese sporting successes in skating, curling, and many forms of skiing are celebrated with displays interesting even to nonsporting types. Outside the museum, take the chairlift to the top of the real ski jump for a chilling view of what athletes face before takeoff. It's a 15-minute bus ride from Maruyama Bus Terminal (¥200).
