World Cup winners Japan slumped to a 2-0 defeat to France in an Olympic Games warm-up match, the team\'s second defeat in their last four outings. A 24th-minute strike from Marie-Laure Delie and a Wendie Renard goal 17 minutes from the end gave France a 17th successive win at the Stade Charlety, on Thursday. It was also the home team\'s seven match in a row in which they had not conceded a goal. Japan, drawn in Group F at the Olympics with Canada, Sweden and South Africa, have lost two of their past four matches since going down 4-1 to the USA in the Volvo Winners\' Cup in Sweden in June. France begin their Olympic campaign against the USA at Hampden Park in Glasgow on July 25, while Japan play Canada at the City of Coventry stadium on the same day.
