Japan's ability at the set piece could be decisive against Qatar in the upcoming AFC Asian Cup final, midfielder Gaku Shibasaki said Wednesday.

In their unbeaten run to Friday's tournament decider, the Samurai Blue have made major weapons of their corners and free kicks, thanks largely to the delivery of dead-ball specialist Shibasaki.

The 26-year-old midfielder for Spanish side Getafe said his boot will be locked in when Japan battle for a record-extending fifth continental title against first-time finalists Qatar at Zayed Sports City Stadium in Abu Dhabi.

"My kicking is feeling better and better. I hope it can be a big asset in the final," said Shibasaki, who teed up Takehiro Tomiyasu's winner with a corner kick against Saudi Arabia in the round of 16.

Aside from playmaking and dead-ball prowess, Shibasaki, with four starts at last summer's World Cup, has provided experience and veteran leadership for Hajime Moriyasu's youthful squad.

"Some of us are accustomed to big-game situations, others aren't," he said. "I know how difficult it can be to perform at your best on such a big stage."

"Having a sense of urgency, while still remaining calm, will help us perform well."

The Samurai Blue went through their paces at training on Wednesday, with midfielder Wataru Endo the only notable absentee.

The holder for Belgian side Sint-Truiden continued to receive treatment after apparently injuring his left thigh in Japan's 3-0 semifinal win over fellow favorites Iran on Monday.

Veteran right-back Hiroki Sakai took part in practice after suffering right foot pain following the semifinal.

Despite going into the final as heavy favorites against Qatar, Japan will not be underestimating the side coached by Spaniard Felix Sanchez, according to Shibasaki.

They should nevertheless be confident of victory, provided they can execute their game plan.

"We've improved in each of our six games. We're heading into the final in good condition," Shibasaki said.
