Nahomi Kawasumi is a Japanese footballer who plays either as a midfielder or forward for Japanese club Albirex Niigata. A full international since 2008, she won gold at the 2011 World Cup as well as silver at the 2012 London Olympics and 2015 World Cup. During the 2011 World Cup, she scored two goals—including a lob at 35 yards away against Sweden during the semifinals—helping Japan eventually win the tournament for the first time in its history.

The women's football tournament at the 2012 Summer Olympics was held in London and five other cities in the United Kingdom from 25 July to 9 August. Associations affiliated with FIFA were invited to enter their women's teams in regional qualifying competitions, from which 11 teams, plus the hosts Great Britain reached the final tournament. There are no age restrictions for the players participating in the tournament. It is the first major FIFA affiliated women's tournament to be staged within the United Kingdom, and marked the first time a team representing Great Britain took part in the women's tournament.
