Japan hosted the 15-a-side Rugby World Cup in 2019, meaning there will be plenty of excitement for the shortened version of the game at the Olympics.
Below, we take a look at the rugby players expected to light up the Tokyo Stadium in 2021, the schedule, and even some history in our guide to Olympic rugby sevens.
When Fiji won the men’s tournament in Rio, Jerry Tuwai was one of the standout players.
Five years later, the man who writes ‘knife’ and ‘fork’ on his boots, arguably still has the fastest footwork in the sport, and as his nation’s captain will be intent on adding another gold medal to his, and Fiji’s, cabinet.
The leading try scorer in world rugby sevens series history Dan Norton is the man to watch for Rio runners-up Great Britain.
The women’s competition will once again be littered with star talent.
Tui recently told Olympic Channel how the Silver Ferns are still smarting from that loss, and even used it to bring about a positive change in their team culture.
All times are Japan Standard Time (GMT/UTC+9)
The competition will take place from 26-31 July.
Rugby sevens will be hosted at enormous Tokyo Stadium, which was built in 2001 and hosted matches at the 2002 FIFA World Cup.
Football and modern pentathlon will also be hosted in this 48,000-seater arena.
Twenty-four teams will take part in the Tokyo Olympics: twelve in each of the men’s and women’s tournaments.
Both competitions will see three groups of four lock horns. The top eight finishers go into the quarterfinals, followed by semis-finals, and a final. The losing semi-finalists play for the bronze medal.
One change from Rio 2016 sees a reverse in the schedule. The men's matches will take place from July 26–28, with the women's sessions being played from July 29–31, 2021. This means the women’s gold medal match will fall on ‘Super Saturday’ – traditionally a highlight of the Games.
The sport of rugby union appeared sporadically at the Olympics between the Paris 1900 and Paris 1924 Games in its 15-a-side format.
After a long absence, rugby sevens - which features faster action due to the extra space players have on the field - debuted at Rio 2016.
Rugby sevens was a success in Brazil, as the Fijian men won the Pacific Island’s first Olympic gold medal ever, while Australia put on an electric display to win the first women’s rugby sevens Olympic champions.
