Jerwin Ancajas is getting himself armed to the teeth as he revs up for what could possibly be his last crack at a world title next month in Tokyo.

A little over a month before he battles Takuma Inoue for the World Boxing Association bantamweight throne, Ancajas was in an upbeat mood, sounding supremely confident of pulling off a major upset at the Ryogoku Kokugikan Sumo Arena.

To achieve optimum performance, Ancajas get quality sparring not just from in-house sparmates King Arthur Villanueva and Jonas Sultan but from others who are brought in on a regular basis.

"I aso spar with guys from other gyms and stables," Ancajas told Daily Tribune from his Las Vegas training camp.

Ancajas, who made nine defenses of the International Boxing Federation super-flyweight crown from September 2016 until early-2022, will leave the United States for Japan on the 3rd or 4th of November.

He should be doing morning roadwork and showing up in the gym the day after his arrival and adjusting to the local conditions.

The duel with Takuma, whose brother Naoya is a pound-for-pound star, was arranged not just by Ohashi Promotions and Teiken Promotions of Japan and Bob Arum's Top Rank Inc.

The main event and choice undercard fights, one of them featuring Sultan against hot prospect Rico Masuda, will be shown live in the US via ESPN+.

This will be the first time that Ancajas, a southpaw, will see action on Japanese soil.
