It was also the biggest margin in an Asian World Cup win, surpassing the previous record of a 2-goal margin shared by Japan, South Korea, Iran, and Australia.
The victory extended Japan's unbeaten World Cup run to 4 matches, a national team record. Center back Ko Itakura completed 80 passes, becoming the first Japanese player to reach that mark in a World Cup game.
The match at Monterrey Stadium in Mexico was the 1000th match in FIFA World Cup history.
