Japan and Denmark will meet in a World Cup decider on Thursday to determine the second team from Group E to advance to the knockout stages.
Japan needs at least a draw, while Denmark must win in order to reach the round of 16. Both teams have three points from two matches, but Japan has a better goal difference.
The Netherlands has already advanced and has six points, while Cameroon was eliminated from the tournament Saturday after losing 2-1 to Denmark.
Denmark coach Morten Olsen views the match against Japan at Royal Bafokeng Stadium as a "final" and said on Tuesday that the team is confident.
