Japan coach Takeshi Okada hopes his players can put a turbulent few weeks behind them and follow South Korea's blueprint for success in their Group E opener against Cameroon on Monday.

South Korea on Saturday brushed aside Greece 2-0 in its first game with the kind of speedy, passing soccer Okada wants his players to produce as they go in search of their first World Cup win on foreign soil in Bloemfontein.

"I saw the game and they (South Korea) really attacked the ball and played so well. They ran their socks off. Now it is our turn," Okada said after Japan practiced under tight security Saturday at a sports facility at the Central University of Technology.
