Meiji Jingu Gaien Stadium

National Stadium (国立競技場, Kokuritsu kyōgijō) was a multi-purpose stadium in Kasumigaoka, Shinjuku, Tokyo, Japan. The stadium served as the main stadium for the opening and closing ceremonies, as well as being the venue for track and field events at the 1964 Summer Olympics. The Japan national football team's home matches and major football club cup finals were held at the stadium. The stadium's official capacity was 57,363, but the seating capacity was only 48,000 seats. Demolition was completed in May 2015, and the site was redeveloped with a new larger-capacity Olympic Stadium. The new stadium was the main venue for the 2020 Summer Olympics and Paralympics. The original plans for the new stadium were scrapped in July 2015 by Japanese prime minister Shinzo Abe, who announced a rebid after a public outcry because of increased building costs. As a result, the new design was not ready for the 2019 Rugby World Cup, as originally intended. A new design created by architect Kengo Kuma was chosen in December 2015 to replace the original design and was completed in November 2019.

Japan was the host nation for the 1964 Summer Olympics in Tokyo. 328 competitors, 270 men and 58 women, took part in 155 events in 21 sports.

The football competition at the 1964 Summer Olympics started on 11 October and ended on 23 October. Only one event, the men's tournament, was contested. The tournament features 14 men's national teams from six continental confederations. The 14 teams are drawn into two groups of four and two groups of three and each group plays a round-robin tournament. At the end of the group stage, the top two teams advanced to the knockout stage, beginning with the quarter-finals and culminating with the gold medal match at the Olympic Stadium on 23 October 1964. There was also three consolation matches played by losing quarter-finalists. The winner of these matches placed fifth in the tournament.

At the 1964 Summer Olympics in Tokyo, the athletics competition included 36 events, 24 for men and 12 for women. The women's 400 metres and women's pentathlon events were newly introduced at these Games. There were a total number of 1016 participating athletes from 82 countries.

The opening ceremony of the delayed 2020 Summer Olympics took place on 23 July 2021 at Olympic Stadium, Tokyo, and was formally opened by Emperor Naruhito. As mandated by the Olympic Charter, the proceedings combined the formal and ceremonial opening of this international sporting event, including welcoming speeches, hoisting of the flags and the parade of athletes, with an artistic spectacle to showcase the host nation's culture and history. The majority of the artistic spectacle was pre-recorded, with live segments performed with a small VIP audience and performers adhering to social distancing. The ceremony marked the 125th anniversary of the 1896 Summer Olympics in Athens—the inaugural edition of the modern Olympic Games. The theme of the Olympic Ceremonies is Moving Forward, referencing the global COVID-19 pandemic, with the opening ceremony theme being the Tokyo 2020 motto United by Emotion, which the organizers intended to "reaffirm the role of sport and the value of the Olympic Games." They focused on responses to the pandemic by the athlete community, including themes of lament, waiting and hope, and to congratulate front-line workers in the athlete community. They also showcased cultural points of Japan such as Japanese theater, video games, and variety shows, such as Kasou Taishou. For the first time in an Olympic opening ceremony, a moment of silence was observed in honor of Israeli athletes and officials murdered in the Munich Massacre at the 1972 Summer Olympics.

The Japan National Stadium, officially named National Stadium (国立競技場, Kokuritsu Kyōgijō) and formerly known as New National Stadium (新国立競技場, Shin Kokuritsu Kyōgijō) or Olympic Stadium (オリンピックスタジアム, Orinpikku Sutajiamu, during 2020 Summer Olympics and Paralympics), is a multi-purpose stadium used mostly for association football in Kasumigaoka, Shinjuku, Tokyo, Japan. The facility served as the main stadium for the opening and closing ceremonies, as well as the venue for track and field athletics events at the 2020 Summer Olympics and 2020 Summer Paralympics in 2021. Demolition of the old National Stadium was completed in May 2015, allowing for the construction of the new stadium to begin on 11 December 2016. The original plans for the new stadium were scrapped in July 2015 by Japanese prime minister Shinzo Abe, who announced a rebid after a public outcry prompted by increased building costs. As a result, the new design was not ready for the 2019 Rugby World Cup, as originally intended. A new design created by architect Kengo Kuma was chosen in December 2015 to replace the original design, which was completed on 30 November 2019.

The Closing Ceremony of the 1964 Summer Olympics took place on October 24, 1964, in the National Olympic Stadium in Tokyo, Japan. The athletes from each country entered informally, despite plans to have a formal entrance. There did not appear to be any backup plan to sort athletes into their respective countries, and as a result the athletes rushed the field, sometimes arm in arm or riding piggyback, in a disorganized and chaotic spectacle. Zambia had just declared independence from Northern Rhodesia on that day and proudly marched under a newly made placard, but other placards were nowhere to be seen. The Japanese television networks were praised for covering the event live without losing their professional demeanor.When order was restored, the officially regulated ceremony was held, overseen by IOC president Avery Brundage. The athletes stood in a circle holding lights, and the large display above the field changed to read "SAYONARA". The national anthems of Greece, Japan, and Mexico as the next Olympic host country were played. As the closing ceremony completed with fireworks, the audience sang Hotaru no Hikari (the tune of Auld Lang Syne). The Showa Emperor was in attendance.
