Japan coach Takeshi Okada is quietly confident his side can return to winning ways in their opening game against Cameroon tomorrow.

Okada insists they will take the game to their opponents at the Free State Stadium. After a run of five warm-up matches without a victory and only one goal scored, he has been accused of negativity for the way he sets his teams up.

However Okada said: "We have never just concentrated on defence. We have skilful players and tomorrow we will be very attack-minded. We have had our ups and downs since I took this post two and a half years ago.

"It is an experience you need to go through and I am not worried. We have done everything we can in terms of our preparation. What I wish for now is our best level of performance."

Takeshi Okada, Japan coach.

It is Okada's second FIFA World Cup™ in charge of Japan after being at the helm in France 98. Okada returned in 2007 when his predecessor Ivica Osim suffered a stroke and guided the Blue Samurai comfortably through the qualifying campaign.

They arrived in South Africa on the back of only two defeats in 14 games.

Okada now wants his players to hit the ground running and said: "We are well tuned. It is down to me to make sure the players are not nervous. We will encourage them as best we can."

Okada is fully aware of the threat posed by Cameroon captain Samuel Eto'o, who could be even more motivated after being handed the armband by coach Paul Le Guen.

The Inter Milan striker carries the hopes of the nation after helping his club win the UEFA Champions League.

Okada said: "I do not think Eto'o is perfect. He is not the only one to focus on as Cameroon have many talented attacking players. But my team have the information they need on Eto'o and we might require more than one man to cover him at times."

Japan arrived yesterday in Bloemfontein, 1400 metres above sea level, from George after deciding not to train at altitude in South Africa.

Okada insists their ten-day pre-tournament training camp in Switzerland was sufficient.

He added: "We got rid of our fatigue by coming back to sea level and that was the important thing for me."
