Jerwin Ancajas doesn't hide the fact that he has Takuma Inoue all figured out.

After viewing Inoue's fights on video, Ancajas swears he has carefully studied the Japanese champion's moves as their 24 February encounter nears.

In fact, Ancajas likens Takuma to his more accomplished brother Naoya, the undisputed super-bantamweight king.

"He fights just like his brother," said Ancajas, who attempts to dethrone Takuma as World Boxing Association bantamweight ruler this Saturday at the Ryogoku Kokugikan Sumo Arena in Tokyo.

The main difference between Takuma and Naoya is glaring.

"The level of power," Ancajas said, noting that Naoya's known as a power puncher and Takuma is not.

In 19 fights, Takuma has scored 18 wins, including just four knockouts.

Ancajas, in contrast, packs a 32-3-2 card with 23 knockouts.

Still, Ancajas believes Takuma can make up his apparent lack of firepower by banking on skills and the support of the home crowd.

And this is also the reason why Ancajas will do his best to dictate the tempo to ensure that the judges would score in his favor if the need arises.

The Filipino southpaw arrived in Tokyo last Sunday oozing with confidence after training long and hard in Las Vegas and the Philippines.
