The 2020 Games were the second of three consecutive Olympics to be held in East Asia, following the 2018 Winter Olympics in Pyeongchang, South Korea and preceding the 2022 Winter Olympics in Beijing, China. Tokyo became the first city in Asia to hold the Summer Games twice. The 2020 Games were the fourth Olympic Games to be held in Japan, following the 1964 Summer Olympics (Tokyo), 1972 Winter Olympics (Sapporo), and 1998 Winter Olympics (Nagano).

The Games were the most expensive ever, with total spending of over $20 billion. 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 first and so far only Olympic Games to be held without official spectators. However, the event retained the Tokyo 2020 branding for marketing purpose. The Games were originally scheduled to take place from 24 July to 9 August 2020, but due to the global COVID-19 pandemic, on 24 March 2020, the event was postponed to 2021, the first such instance in the history of the Olympic Games (previous games had been cancelled but not rescheduled).

Tokyo was selected as the host city during the 125th IOC Session in Buenos Aires, Argentina, on 7 September 2013.

The 2020 Summer Olympics ( Japanese: 2020年夏季オリンピック, Hepburn: Nisen Nijū-nen Kaki Orinpikku), officially the Games of the XXXII Olympiad ( 第三十二回オリンピック競技大会, Dai Sanjūni-kai Orinpikku Kyōgi Taikai ) and also known as Tokyo 2020 ( 東京2020, Tōkyō Nii Zero Nii Zero), 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.
