For the first time since defeating Mexican Luis Nery in May in front of 55,000 fans at the Tokyo Dome, Inoue, who has a record of 27 wins and 0 losses (24 by knockout), will step into the ring. He will do so to face Irishman Doheny (26-4, 20 KOs), who held the IBF super bantamweight title from 2018 to 2019.

This will be Inoue's seventh straight fight in Japan and his fourth fight at the 12,000-seat Ariake Arena since 2022. He always fights during the week to respect tradition, and this time he will do so in front of a smaller crowd in the Japanese capital, but his attitude remains the same with all four belts on the line.

"The pressure doesn't change. It doesn't matter that the last fight was in the Tokyo Dome," he told reporters after making weight for the fight on Monday. "The enjoyment I get from fighting is the main thing. It doesn't matter where the fight takes place, when I step into the ring I have expectations of myself. I'm looking forward to it," he added.

He is looking to regain his throne, retain the undisputed crown and keep all four super bantamweight belts. Inoue is regarded as one of the best boxers in the world pound-for-pound at the moment. The 31-year-old Japanese fighter once again demonstrated his ferocious power against Nery in his first title defence since becoming undisputed super bantamweight champion last December.

However, he had to recover from being knocked down for the first time in his career when the Mexican floored him in the first round. Inoue got up and knocked his opponent down in the next round before sending him to the canvas again in the fifth and finishing him off with a right hook in the sixth.

Inoue is only the second man to become undisputed world champion in two different weight classes since the four-belt era began in 2004. The first was American Terence Crawford.

He will be the overwhelming favourite against the 37-year-old Doheny. Doheny's last fight was against Bryl Bayagos of the Philippines on the undercard of Inoue's fight at the Tokyo Dome. He has been beaten four times but has never been knocked out. Doheny has fought his last three bouts in Japan, winning each by technical knockout in the fourth round.

Inoue said he expected Doheny to come in significantly heavier than his weigh-in mark of 55.1kg. "However, in boxing, it's not just about who's physically bigger." Inoue said. "Tomorrow I want to show my boxing skills," he concluded before taking a break.

Inoue became undisputed bantamweight champion in December 2022 and is a four-division world champion. He was also the first undisputed junior featherweight champion. Inoue defeated unified champions Stephen Fulton and Marlon Tapales in consecutive fights.
