TOKYO (AFP) - Japan can overcome losing half their defence to injury and take a big step towards World Cup qualification this week, their Liverpool forward Takumi Minamino said on Wednesday (Jan 26).

Captain Maya Yoshida and Arsenal fullback Takehiro Tomiyasu have both been ruled out of Japan's crunch home qualifiers against China on Thursday and Saudi Arabia on Feb 1.

But Minamino insisted the four-time Asian champions have enough quality in reserve to get the job done and move closer to a seventh straight World Cup appearance in Qatar.

"For sure, not having our captain can be a negative, but it's in times like this that the team come together," said Minamino.

"It's a team sport so we just have to get over it. We're not paying too much attention to that and we have a lot of other good players."

Yoshida was injured playing for Italian club side Sampdoria earlier this month, while Tomiyasu pulled out of the squad on Sunday.

Japan have recovered from a rocky start to climb into second place in Group B, one point ahead of third-place Australia and four behind leaders Saudi Arabia.

Hajime Moriyasu's side head into their game against China on the back of three straight wins and the manager is confident they can cope.

"Maya and Tomi have contributed a lot and it's a big loss not to have them here, but it will hurt them more than anyone," he said.

"New players will come in to replace them and we will have to get used to a new combination. But I want all the players to come together and show their strengths as they do with their clubs and play with confidence."

China are currently in fifth place in the group, seven points adrift of Japan in the second automatic qualification spot.
