These games were also the first to be telecast internationally without the need for tapes to be flown overseas, as they had been for the 1960 Olympics four years earlier. The games were telecast to the United States using Syncom 3, the first geostationary communication satellite, and from there to Europe using Relay 1. These were also the first Olympic Games to have color telecasts, albeit partially. Certain events like the sumo wrestling and judo matches, sports huge in Japan, were tried out using Toshiba's new colour transmission system, but only for the domestic market. History surrounding the 1964 Olympics was chronicled in the 1965 documentary film Tokyo Olympiad, directed by Kon Ichikawa.
The games were scheduled for mid-October to avoid the city's midsummer heat and humidity and the September typhoon season. The previous Olympics in Rome in 1960 started in late August and experienced hot weather. The following games in 1968 in Mexico City also began in October.
The 1964 Olympics were also the last to use a traditional cinder track for the track events. A smooth, synthetic, all-weather track was used for the first time at the 1968 Olympics and at every Olympiad thereafter.
