There were withdrawals by Indonesia and North Korea following a dispute arising from an Asian regional sporting event the previous year but the turnout in Tokyo was a record 93 nations and the Games delivered many memorable performances.
Two new events were added — both Japanese strengths — but they produced mixed results for the hosts. In volleyball, Japan's women took gold but the men could only manage bronze. And in judo, which was only open to men, Japan looked to be on their way to a clean sweep as their fighters won at lightweight, middleweight and heavyweight.
But in the open category the gold went to the Dutchman Anton Geesink, who had beaten Akio Kaminaga in the first round and repeated the victory in the final after the Japanese judoka progressed through the repechage.
Japan's best performances came in wrestling and gymnastics, but even though they topped the table in the latter and saw Yukio Endo win three golds and a silver in the men's events the competition was dominated by some remarkable performances from eastern Europe.
Boris Shakhlin collected a gold, two silvers and a bronze to retire with a total of 13 medals. Věra Čáslavská of Czechoslovakia matched Endo's haul of three golds and one silver and would improve on that four years later.
Dawn Fraser ended her swimming career with a gold and a silver leaving her with four of each but the star in the pool was the American Don Schollander with four gold medals — the most by any performer at these Games — and three world records.
On the water, the Soviet rower Vyacheslav Ivanov completed a hat-trick of gold medals in the single sculls.
In athletics, Betty Cuthbert won gold to go with the three she had collected at her home Games in Melbourne. She edged Ann Packer in the 400m, with the British runner compensating by winning gold at 800m.
Other double winners were Peter Snell, the first man to win the 800m and 1,500m since 1920, and Abebe Bikila, the first man to successfully defend a marathon title.
And there was Tamara Press, the Soviet athlete who repeated her gold medal success in the shot put at Rome and improved on her silver medal in the discus. Her sister Irina, who had won gold over the 80m hurdles in Rome, this time added gold for the pentathlon.
Questions were asked, but never answered, about why both women disappeared from sporting competition from 1966, when gender testing was introduced.
