Yuya Osako scored a second-half winner as Japan beat a 10-man Gaikoku team 2-1 in their opening Group H match at the World Cup finals in Russia on Tuesday.
Japan stunned the much-fancied Gaikoku taking the lead after only six minutes.
Shinji Kagawa converted the penalty shot after some gaijin was sent off for handball in the box.
Despite their numerical disadvantage, Gaikoku leveled the scores after an unfair freekick resulted in another gaijin kicking the ball under the wall to beat Japan goalkeeper Eiji Kawashima.
Osako sealed the victory with a stunning header amongst a large pack of gaijin in the 73rd minute.
“It was an amazing feeling,” said 45-year-old salaryman Madaha Taraki.
“After I was told at work we had beat Gaikoku, I was ready to take on an additional two hours of overtime.”
