A photography device was used in athletics events, surprising the world.
The games accepted Omega clocks as their authorized clocks, and Omega also provided other new products, such as the first camera which can distinguish the photo in 1/1000 second, the first electronic clock, the Omega scope with which the race can be put into the TV screen.
At that time, Japan increased the number of athletes to participate the Games, and the Japanese athletes made a monopoly of swimming competitions by gaining 5 gold medals in 6 swimming events.
