Shinji Okazaki scored a hat trick and Ryoichi Maeda a bace as Japan stormed into the quarter finals of the AFC Asian Cup 2011 with 5-0 victory over Saudi Arabia on Monday.
The Blue Samurai will now play host Qatar on Friday after topping tournament Group B with seven points from two wins and a draw.
