The 1964 Summer Olympics, officially known as the Games of the XVIII Olympiad, were held in Tokyo, Japan.

93 countries participated in the first Olympics to be held in Asia. As a tribute to the horrors of the Second World War, Yoshinori Sakai, who was born in Hiroshima on August 6, 1945, the day an atomic bomb destroyed the city, was chosen as the torchbearer to light the Olympic flame during the opening. The Tokyo Olympics was also the first Olympic Games that used satellites – Syncom 3 in the United States and Relay 1 in Europe – to telecast the games. Some of the games were also broadcasted in color for the first time.
