# Japan at the 2024 Summer Olympics

Japan, the previous host of the 2020 Olympics at Tokyo, competed at the 2024 Summer Olympics in Paris from 26 July to 11 August 2024. Japanese athletes have appeared in every edition of the Summer Olympic Games from 1912 onwards, except for two occasions: the 1948 Summer Olympics in London, to which they were not invited because of the nation's role in World War II, and the 1980 Summer Olympics in Moscow, due to their participation in the United States-led boycott.

## Gymnastics
### Artistic

Japan fielded a full squad of male and female artistic gymnasts for Paris. Five male gymnasts qualified for the games after scoring a runner-up finish in the team all-around at the 2022 World Championships in Liverpool, Great Britain. Meanwhile, the five female gymnasts qualified for the games after advancing to the final round of the team all-around at the 2023 World Championships in Antwerp, Belgium, obtaining one of nine available team spots for nations not yet qualified.
The five members of the men's and women's teams were announced in May 2024 after the conclusion of the NHK Trophy. For the first time in 40 years, all members named to the women's team were slated to be first-time Olympians. The men's team is led by Daiki Hashimoto, the defending Olympic all-around champion. In mid-July, nineteen-year-old Shoko Miyata was removed from the Japanese women's team after smoking and drinking alcohol, which are prohibited in Japan for those under 20. Since Miyata was removed for a reason other than injury, no athlete substitution was made. Thus, the women's team is anticipated to compete with only four athletes.
