Japan moved through to the last 16 at the FIFA U-17 World Cup in Mexico with a 3-1 win against a 10-man Argentina in Morelia.
Argentina now faces an anxious wait to see if three points are enough to take it through as one of the top third-place finishers.
Japan controlled play from the opening whistle and proved a class above its South American opponent in all facets of the game.
Argentina began the game is sloppy fashion and found itself a goal down to the lively Japanese after just four minutes when Naoki Kawaguchi found space on the right and shot for goal from a tight angle.
Argentinean goalkeeper Nicholas Sequeira failed to get a hold of the shot and defender Daisuke Taikagi was on hand to ram home the goal.
Argentina woke up after the goal and created two quick chances, a Edgardo Bárez header and a stinging shot from Lucas Ocampo.
The Japanese continued to dominte as the half progressed, however, and Naomichi Ueda doubled their lead in the 20th minute when he headed home into the top corner of Sequeira’s goal.
Five minutes into the second half, Takumi Minamino made a clever run into the box but couldn't beat the keeper. Ocampos had a good chance at the other end seconds later, but his skillful shot flew just wide of Ayumi Niekawa’s post.
Matias Montero was shown a red card for stomping on Hiroki Akino in the 68th minute, further adding to Argentina's woes.
The Japanese midfielder recovered to score Japan’s third in the 74th minute, though, finding his own rebound as Sequeira’s horror day only got worse.
Argentina's only joy came 87th minute when Brian Ferreira chipped the Japanese goalkeeper superbly from near the halfway line.
The would have been scant consolation however, as Japan is now through to the knockout rounds as the Group B winner, after France and Jamaica shared the spoils in the final Group match.
The French will join Japan in the next round as runner-up while Argentina is unlikely to progress with its three points.
Jamaica was eliminated after managing just one point.
