# Japan at the 2016 Summer Olympics

Japan competed at the 2016 Summer Olympics in Rio de Janeiro, Brazil, from 5 to 21 August 2016. Since the nation's official debut in 1912, Japanese athletes had appeared at every Summer Olympic Games in the modern era, except for two editions; they were not invited to the 1948 Summer Olympics in London because of the nation's role in World War II, and were also part of the United States-led boycott, when Moscow hosted the 1980 Summer Olympics.
As Tokyo was the host city of the 2020 Summer Olympics, a Japanese segment was performed during the closing ceremony. The Olympic flag was handed to Yuriko Koike, the Governor of Tokyo from Mayor of Rio de Janeiro, Eduardo Paes, who passed it to IOC President Thomas Bach before handed it to her. Prime Minister Shinzo Abe was present in the ceremony, dressed as Nintendo's Mario character. He travelled underground from Tokyo to Rio using the tunnel that was created in animation by both Nintendo and the Japanese Olympic Committee.

## Athletics

Japanese athletes have so far achieved qualifying standards in the following athletics events (up to a maximum of 3 athletes in each event): The team was selected based on the results of the 2016 Japan Championships in Athletics, and once an athlete wins a medal in race walking and marathon, or attains the top eight position in track and field at the 2015 IAAF World Championships in Beijing, China.
On 17 March 2016, the Japan Association of Athletics Federations (JAAF) had selected three runners each in both men's and women's marathon race, with Kayoko Fukushi remarkably going to her fourth consecutive Olympics. Forty-two further athletes (31 men and 11 women) were added to the nation's track and field roster for the Games, based on their performances achieved at the Japan Championships (24 to 26 June). Among them were sprinters Chisato Fukushima and Shota Iizuka, 2015 Worlds bronze medalist and three-time Olympic race walker Takayuki Tanii, and javelin thrower Ryohei Arai.

## Weightlifting

Japanese weightlifters have qualified three men's and four women's quota places for the Rio Olympics based on their combined team standing by points at the 2014 and 2015 IWF World Championships. The team must allocate these places to individual athletes by 20 June 2016.
The weightlifting team was named to the Olympic roster on 28 May 2016, with London 2012 silver medalist Hiromi Miyake remarkably going to her fourth straight Games. Two further places were added to the Japanese weightlifting squad, as a response to Azerbaijan's omission from the ranking list published at the World Championships, due to "multiple positive cases" of doping on the nation's weightlifters.
