Japan star Honda savours winning goal
The Cameroon defence failed to cut out Daisuke Matsui's cross to the back post in the 39th minute and Honda reacted quickly, producing a superb first touch before clipping the ball beyond stranded goalkeeper Souleymanou Hamidou.
Japan then defended resolutely to regain that winning mentality after a run of five warm-up matches without a victory.
Honda's career is on an upward curve as he joined CSKA Moscow at the turn of the year from Dutch club VVV Venlo and helped the Russian club reach the quarter-finals of the Champions League.
"This goal was a nice birthday present for me. I am so happy now and there is a great atmosphere in the team," Honda said after the game.
"We were able to stop Cameroon's attacking players and I think that was why we were able to get a good result. We had confidence before the game.
"Of course we played badly in the friendly matches but we didn't mind about this because they were not so important. We were only concentrating on today.''
