Yuji Nakazawa, Yasuhito Okubo and Shunsuke Nakamura were on target as the hosts got their Group Two campaign back on track at Nissan Stadium.

Takeshi Okada's side dominated right from the first whistle on a damp evening in Yokohama to claim their second win in three games.

They could have been in front inside the opening three minutes only for Keiji Tamada to mistime his volley after the ball fell to him on the edge of the area, sending his effort over the bar.

Japan did not have long to wait for the breakthrough though as Nakazawa escaped his marker Nabil Ashoor and headed home Yasuhito Endo's corner after 10 minutes.

Mohamed Mubarek tried his luck from long range as Oman looked to respond, but his effort was off-target.

But it was Japan's Celtic playmaker Nakamura who was pulling the strings in midfield and he created a second for his side in the 22nd minute.

The dead-ball specialist picked out Marcus Tulio Tanaka with a pin-point lofted pass from the halfway line.

The Urawa Reds defender headed the ball into the path of the onrushing Okubo, who steered his finish past Oman goalkeeper Ali Al Habsi.

The home side rounded off a routine victory four minutes into the second half when the impressive Nakamura capitalised on Daisuke Matsui's tackle in midfield to create space for a shot before sending a low 20-yard shot skidding past Al Habsi.

With the game won, the Japanese sat back in the closing stages, but substitute Shinji Kagawa could have made it four late on when he headed straight at Al Habsi.
