Wrestling at the 1964 Summer Olympics – Men's freestyle flyweight
The men's freestyle flyweight competition at the 1964 Summer Olympics in Tokyo took place from 11 to 14 October at the Komazawa Gymnasium. Nations were limited to one competitor.
Competition format
This freestyle wrestling competition continued to use the "bad points" elimination system introduced at the 1928 Summer Olympics for Greco-Roman and at the 1932 Summer Olympics for freestyle wrestling, as adjusted at the 1960 Summer Olympics. Each bout awarded 4 points. If the victory was by fall, the winner received 0 and the loser 4. If the victory was by decision, the winner received 1 and the loser 3. If the bout was tied, each wrestler received 2 points. A wrestler who accumulated 6 or more points was eliminated. Rounds continued until there were 3 or fewer uneliminated wrestlers. If only 1 wrestler remained, he received the gold medal. If 2 wrestlers remained, point totals were ignored and they faced each other for gold and silver. If 3 wrestlers remained, point totals were ignored and a round-robin was held among those 3 to determine medals.Results
