3 on 3 basketball is a new addition to the Olympics and we have the sport's first winners.
In the women's tournament the U.S. took home the gold beating the team from Russia 18 to 15.
In the men's event, Latvia beat their Russian counterparts 21 to 18 giving the Eastern European nation their first medal in Tokyo.
This event is faster, more physical and has fewer pauses than conventional basketball.
Matches are 10 minutes-long or finish after one of the teams scores 21 points.
