As previously reported by The Ring, Japanese star Naoya Inoue will defend his undisputed junior featherweight world title against San Antonio native Ramon Cardenas on Sunday, May 4, at T-Mobile Arena in Las Vegas, Nevada.

Inoue has not fought in America since 2021 and has since won a pair of undisputed titles, cementing his status as a generational power-punching force.

“Naoya Inoue is among the most powerful and well-rounded fighters I’ve had the privilege of promoting, a singular boxing talent,” said Top Rank Chairman Bob Arum. “After many years selling out arenas and stadiums in his native Japan, ‘The Monster’ is ready to take over Las Vegas on Cinco de Mayo weekend. Ramon Cardenas is a worthy challenger who has earned this opportunity with several impressive victories.”

Inoue (29-0, 26 KOs) is 24-0 with 22 knockouts in world title fights. Last May, he packed over 50,000 fans into the Tokyo Dome, rising from a first-round knockdown to stop former two-division king Luis Nery in six. Inoue has since made two more defenses of the undisputed crown, knocking out TJ Doheny in seven and late replacement Ye Joon Kim in four.

Inoue said, “I am thankful to the fans in America who have followed my career. Fighting at T-Mobile Arena in Las Vegas is another career highlight, and I look forward to putting on a great show for everyone in attendance. Cardenas is a tough opponent who I respect for accepting the fight without hesitation.”

Cardenas (26-1, 14 KOs) enters his first world title assignment on a 14-fight winning streak, a run of success that began with a September 2017 decision victory over Gabino Hernandez.

“This means the world to me. I’ve always aspired to fight for a world title, but to get a chance to fight for all the belts is a dream come true,” Cardenas said. “I always knew our paths would cross. I never had any doubts. When the fight was offered, I instantly accepted. I wouldn’t say it’s a lottery ticket, but you can't turn it down if you get a chance at the undisputed title. This is the opportunity of a lifetime.”
