The 2020 Summer Olympics, officially the Games of the XXXII Olympiad and branded as Tokyo 2020, was an international multi-sport event held from 23 July to 8 August 2021 in Tokyo, Japan, with some preliminary events that began on 21 July.
Tokyo was selected as the host city during the 125th IOC Session in Buenos Aires, Argentina, on 7 September 2013. Originally scheduled to take place from 24 July to 9 August 2020, the event was postponed to 2021 in March 2020 as a result of the COVID-19 pandemic, the first such instance in the history of the Olympic Games. However, the event retained the Tokyo 2020 name for marketing and branding purposes. It was largely held behind closed doors with no public spectators permitted due to the declaration of a state of emergency in the Greater Tokyo Area in response to the pandemic. The Summer Paralympics were held between 24 August and 5 September 2021, 16 days after the completion of the Olympics.
The 2020 Games were the fourth Olympic Games to be held in Japan, following the Tokyo 1964, Sapporo 1972 and Nagano 1998 games. Tokyo was the first city in Asia to hold the Summer Games twice.
