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.
