TRANSPAC-1, the first trans-Pacific communications cable from Japan to Hawaii was also finished in June 1964 in time for these games. Before this, most communications from Japan to other countries were via shortwave.[15]
The start of operations for the first Japanese "bullet train" (the Tokaido Shinkansen) between Tokyo Station and Shin-Ōsaka Station was scheduled to coincide with the Olympic games. The first regularly scheduled train ran on October 1, 1964, just 9 days before the opening of the games, transporting passengers 515 kilometers (320 mi) in about 4 hours, and connecting the three major metropolitan areas of Tokyo, Nagoya, and Osaka.
Some already-planned upgrades to both highways and commuter rail lines were rescheduled for completion in time for these games. Of the 8 main expressways approved by the Tokyo Metropolitan Government in 1959, No. 1, No. 4 and a portion of No. 2 and No. 3 were completed for the games. Two subway lines totaling 22 kilometers (14 mi) were also completed in time for the games, and the port of Tokyo facilities were expanded to handle the anticipated traffic.[16]
