In March 2020, the International Olympic Committee agreed to postpone the Games until 2021 due to concerns over Covid-19. The event was originally set to begin on July 24, 2020 and end on Aug. 9, 2020.
"The IOC president and the Prime Minister of Japan have concluded that the Games ... must be rescheduled to a date beyond 2020 but not later than summer 2021, to safeguard the health of the athletes, everybody involved in the Olympic Games and the international community," a statement from the International Olympic Committee and the Tokyo 2020 Organising Committee read.
With the postponement, officials decided that the Games — which would take place in 2021 — would still be called the Tokyo 2020 Olympics.
The decision to push back the event was the first of its kind in Olympics history. The Games have never been postponed, although they have been canceled on three occasions due to World Wars in 1916, 1940 and 1944.
