Kensuke Nagai: Celebrates his opening goal against Senegal in the quarter-finals
Brazil, Japan and Mexico have secured their places in the last four of the Olympics after coming through their respective quarter-final games.
The team from the Land of the Rising Sun cruised past Egypt who had impressed at the London 2012 games.
Kensuke Nagai gave Japan the lead and just before the interval, the Africans' chances of regaining a foothold in the tie were severely reduced when Saad Samir was dismissed.
However, after the break they enjoyed large periods of possession but were unable to translate it into meaningful chances on goal.
The game was effectively settled when Maya Yoshida and Yuki Otsu claimed further goals to put Japan into the semi-finals.
Japan will now face Mexico in their semi-final clash after the South Americans edged past Senegal 4-2 following extra time.
In front of almost 82,000 at Wembley, goals from Jose Enriquez and Javier Aquino gave them the advantage just after the hour mark.
However, the west Africans were soon back in the match. Moussa Konate scored his and Senegal's fifth goal of the competition to resuscitate their hopes of success.
And then substitute Ibrahima Balde levelled the scores to put them right back in contention for victory as the match finished level.
Extra time arrived and then ruinous defending from the Africans allowed firstly Giovani Dos Santos to score, before substitute Hector Herrera's strike confirmed the win.
Lastly, Brazil confirmed their place in the semis with a hard-fought 3-2 win over nine-men Honduras.
Mario Martínez gave Honduras a surprise early lead but their momentum was checked when Wilmer Crisanto was dismissed for two yellow cards.
Leandro Damiao's strike brought Brazil back into the game and the teams went into the interval on level terms.
Roger Espinoza gave Honduras the lead soon after the break but a penalty from Neymar and another Damiao goal put Brazil in firm control.
Espinoza was sent off in stoppage time for his second bookable offence as Brazil marched into the semis.
