125th IOC Session

The announcement was met with jubilation from the Tokyo delegation and across Japan.[3] Japanese prime minister Shinzō Abe, who had given a personal address during the presentation stage, said "I would like to thank everyone in the Olympic movement and we will host a wonderful Olympic Games." Japanese fencer Yuki Ota alluded to the 2011 earthquake in a statement to reporters, "After the earthquake everyone in Japan was depressed but now we have to make a dream come true."

Abe's role in the final stages of the bid, including his reassurances to the IOC that Fukushima radiation would not affect Tokyo, was considered to be a major asset. Tokyo's bid had also received support from Princess Hisako and Sheikh Ahmad Al-Fahad Al-Sabah.[4] Madrid's bid was considered to have been hampered by Spain's weak economy and Istanbul's was considered to have been damaged by recent internal political instability and doping scandals, as well as match fixing in 2011.[4][5]

Baseball was first included as a demonstration sport at the 1904 Summer Olympics in St. Louis. It was again played as a demonstration sport at the Summer Olympics in 1912, 1936, 1956, 1964, 1984, and 1988. It was first included as an official medal sport at the 1992 Summer Olympics in Barcelona. Baseball then featured at every Summer Olympic Games until the 2008 Olympics in Beijing, where it made its last Olympic appearance.

Softball was included at the Summer Olympics in 1996, 2000, 2004, and 2008.

The governing bodies for baseball (International Baseball Federation) and softball (International Softball Federation) merged in 2013 to form the World Baseball Softball Confederation. The two sports each had a separate bid for joining the Olympic program.[11]

Squash is played in more than 185 countries and by millions of people worldwide.[12] It has been played at various international sporting events, including the Pan American Games since 1995, and the All-Africa Games since 2003. Squash has also been played at both the Commonwealth Games and the Asian Games since 1998.

The sport is governed by the World Squash Federation.

Wrestling is practiced all around the world, officially in 177 countries, some of which participate in the Olympic Games in this sport alone. It was first introduced in the ancient Olympic Games in 708 BC and was included in all the ancient Olympics from that date. Wrestling has featured at the modern Summer Games since the 1896 Olympics in Athens, and it has been a part of all modern Olympics except those in Paris in 1900. It was still included in the Olympic program at the 2016 Summer Olympics in Rio de Janeiro. Wrestling was initially dropped from the 2020 Olympic program; however, it was given the opportunity to be reselected for the 2020 and 2024 Games.[13]

The sport is governed by United World Wrestling.
