He also mentioned that his body can reach the limit to featherweight.
Naoya Inoue became the ninth fighter to unify all four major titles in boxing's four-belt era.
Inoue is now looking to become the only male fighter to accomplish the feat in two weight classes.
"I believe I'm going to aim for it," Inoue said. "We'll need to develop a thorough plan."
The Japanese star will be heading up to 122-pounds, after knocking out British fighter Paul Butler in eleven rounds to unify the IBF, WBO, WBA, WBC world bantamweight titles.
Inoue plans to return on a date in April or May of the coming year.
The world titles at 122-pounds are owned by two undefeated fighters, Uzbekistan's Murodjon Akhmadaliev and Stephen Fulton of the United States - with each boxer holding two belts.

"Thorough plan." Yes, he will need it as this is a new jungle that he will be up against. He may have dominated his weight class but I am sure the boxers in the next will not just give him what he wants to happen.
Challenges will pour out in his schedule.
Interesting to wait if who among these title holders will be Inoue's target to deal with and call for a challenge fight,
his comeback to formally announce his plan to move up will bring a big hype.
After dominating his current division, it will be a big challenge to him, those belt holders from 122lbs are also
excited to face him.
It would be a good risk for Inoue and whoever champ that he will challenge.
