Watch all the five goals scored by Japan against Ghana in the FIFA U-17 Women's World Cup on Saturday
Riko Ueki fired the Young Nadeshiko into an early lead on seven minutes taking Japan's goals tally in the history of the tournament to 80, the most of any nation.
Jun Endo doubled his side's lead with a left footed strike that found the top opposite corner, before she made it 3-0
Five minutes after Endo's second, it was Saori Takarada's turn to get on the scoresheet. After superb work on the right wing, Riko Ueki evaded her defenders and made space for herself before looking up and finding Takarada with a perfect cross and Ueki made no mistake with a firm header that sailed past Ghana keeper Barikisu Issahaku.
It wasn't until the last quarter of an hour in the first half that Ghana were able to catch their breath and prevent Japan from creating any clear goalscoring opportunities. That carried into the second half as Ghana almost held Japan to a goalless 45 minutes until Remina Chiba made it five late on.
In the end, it was a comfortable win for the holders as they claim three points early in Group D play ahead of matches against Paraguay and USA later in the tournament.
Ghana is the only African nation to have reached the semi-finals in the tournament's history, so coach Evans Adotey and his team will be needing to bounce back from the defeat, starting with their meeting with USA on Tuesday, if they are going to replicate or better that performance.
