For the 1972 Winter Olympics in Sapporo, Japan, a total of twelve sports venues were used. A thirteenth venue which was a reserved luge course was constructed, but never used in actual competition. Construction on all but of the venues used took place between 1968 and early 1971 in time for the test events. The Tsuskisamu Indoor Skating Rink was not completed until late 1971 or early 1972 because the number of teams scheduled to compete at the 1972 Games was not known. At the actual luge venue used, a malfunctioning starting gate during the first run led to the results being cancelled and rerun being ordered. The results of this event led to the only tie in Olympic luge history. The ski jumps at Miyanomori and Okurayama served as host venues for the FIS Nordic World Ski Championships thirty-five years later. Venues City A reserve luge course was constructed south of Sapporo's Olympic village at the Fujino ski area, but was never used. Constructed between June 1968 and November 1971, the track cost ¥106 million to build. It was long for men's singles and long for women's singles and men's doubles, had 14 turns for all three luge disciplines, and had a 10% average gradient for the track. No turn names were given. Mountain Before the Olympics At the 1936 Winter Olympics in Garmisch-Partenkirchen, Germany, the International Olympic Committee (IOC), the decision to award the 1940 Winter Olympics was suspended. This was because of an issue with amateurism between the IOC and the International Ski Federation. Three years earlier, at an IOC meeting in Oslo, Japan had expressed an interest in hosting the Winter Olympics, with Sapporo and Nikkō as possible locations, though four other sites were also considered. Because Tokyo had been awarded host of the 1940 Summer Olympics, the IOC awarded Japan the 1940 Winter Games. This was confirmed by the IOC at the 1937 meeting in Cairo on the condition that the 1940 Games would be given to Norway if Japan could not organize the preparations by the fall of 1938. One of the venues of the 1940 Winter Games that would be included in the 1972 Winter Olympics was the Mount Okura ski jump. In July 1937, Japan's second invasion of China began, and despite being awarded the 1940 Winter Olympics, Sapporo was forced to withdraw from hosting the 1940 Winter Olympics as was Tokyo
