On 7 September 2013, outgoing International Olympic Committee President Jacques Rogge declared “The Games of the 32nd Olympiad in 2020 are awarded to the city of… Tokyo!” The IOC decision in Buenos Aires, Argentina sees the Games return to Japan’s capital Tokyo over half a century after hosting the Games in 1964.
Due to the unprecedented effects of the coronavirus (COVID-19) in early 2020, the Tokyo 2020 Olympic Games were moved exactly a year later to the 23 July – 8 August 2021.
