The town of Iizuna, approximately 12 kilometers northwest of Nagano, was the site of freestyle skiing and bobsleigh, luge, and skeleton at Iizuna Kogen Ski Area. 8,000 spectators can watch the free style skiing on a course that 250 meters long and 12,000 can watch the jumps. The Spiral, which held the sledding events, was the first artificially refrigerated track in Asia. It is 1700 meters long, with a difference in height of 114 meters and 15 turns. At the Spiral, approximately 40,000 saplings, mainly beech and oak, were planted two per square meter, as part of the environmental stewardship committed during the Winter Games. The site can accommodate 10,000 spectators.
