Full undercard preview: Who fights before Inoue vs Nakatani?

The undercard is stacked with Japanese talent and international contenders. While the main event is the clear headliner, several bouts offer serious intrigue for hardcore fans. Here is the confirmed lineup:

• Takuma Inoue vs. Ryosuke Nishida (bantamweight): Takuma, Naoya’s younger brother, defends his WBA bantamweight title against the unbeaten Nishida. This is a genuine 50-50 fight and could steal the show. Nishida (27-0, 8 KOs) has superb fundamentals, while Takuma (20-1, 5 KOs) relies on slick counter-punching. Expect a technical chess match.
• Kenshiro Teraji vs. Carlos Canizales (light flyweight): Former unified champion Teraji returns after a brief layoff. He faces the hard-hitting Venezuelan Canizales, who has 27 KOs in 30 wins. Teraji’s speed and body work will be tested against Canizales’ relentless pressure.
• Yudai Shigeoka vs. Melvin Jerusalem (minimumweight): A unification bout in the smallest division. Shigeoka, the WBC champion, meets WBO king Jerusalem. Both are undefeated and known for explosive power at 105 pounds. This could be a short, violent affair.
• Hiramoto Keita vs. Shavkat Rakhimov (super featherweight): A crossroads fight for former world champion Rakhimov, who looks to rebound after losing his belt. Keita is a heavy-handed domestic contender eager to make a name.

The undercard depth is exceptional. Every bout features either a world champion or a top-10 contender, making the entire broadcast worth watching from the opening bell.

Expert analysis: Why this fight is a true 50-50

On paper, this is the most dangerous fight of Naoya Inoue’s career. The 33-year-old “Monster” has demolished everyone in his path, from Nonito Donaire to Stephen Fulton to Marlon Tapales. But Junto Nakatani presents a unique set of problems.

Nakatani’s advantages:

• Reach and height: At 5-foot-8 with a 71-inch reach, Nakatani is a giant for super-bantamweight. He will tower over Inoue, who stands 5-foot-5 with a 67-inch reach. Expect Nakatani to use his jab as a rangefinder and try to keep Inoue on the outside.
• Power in both hands: Nakatani has 24 KOs in 32 wins, including a devastating knockout of Andrew Moloney. His left hook is a legitimate fight-ender.
• Adaptability: He has won titles at flyweight, bantamweight, and super-bantamweight. He knows how to adjust mid-fight.

Inoue’s advantages:

• Punching power and accuracy: Inoue’s 27 KOs in 32 wins include some of the most brutal body shots in boxing. He is a surgical puncher who lands with terrifying precision.
• Ring IQ: Inoue’s ability to read opponents and make adjustments is second to none. He dismantled Fulton, a slick boxer, in eight rounds.
• Experience at the weight: This is Nakatani’s second fight at super-bantamweight. Inoue has been here for years and knows the division’s nuances.

The X-factor: Nakatani’s December move up in weight was not smooth. He scraped past Sebastian Hernandez Reyes via a close majority decision. That fight exposed some vulnerability to pressure and body punching—Inoue’s specialty. Conversely, Inoue outclassed Alan Picasso on the same night, showing he is still at peak form.

Predictions: Who wins Inoue vs Nakatani?

This is a genuine pick-‘em fight among analysts. I have gone back and forth for weeks, but here is my breakdown:

Early rounds (1-4): Expect a feeling-out process. Nakatani will use his jab and lateral movement to keep Inoue at bay. Inoue will stalk, looking for openings to the body. Nakatani may win the first two rounds on activity, but Inoue will land a few sharp counters.

Middle rounds (5-8): Inoue will begin to close the distance. His head movement and footwork are elite. He will start targeting Nakatani’s midsection, forcing the taller man to drop his hands. This is where the fight turns. Inoue’s body shots will slow Nakatani down.

Championship rounds (9-12): If Nakatani survives the body assault, his stamina will be tested. He has never been past 10 rounds at this weight. Inoue, a proven finisher, will pour on the pressure. I see a late stoppage or a clear unanimous decision for Inoue.

My prediction: Naoya Inoue by TKO in round 10. Nakatani will be brave, but the weight jump and Inoue’s relentless body attack will prove too much. However, if Nakatani can keep the fight at long range and land his left hook, he has a puncher’s chance. Do not sleep on the upset.

Strong conclusion: A fight for the ages

Inoue vs Nakatani is more than just a title unification. It is a cultural moment for Japanese boxing, a sport that has produced legends from Fighting Harada to Ryota Murata. Both men represent the pinnacle of discipline, skill, and courage.

For Inoue, a win cements his legacy as one of the greatest fighters of all time—regardless of weight class. For Nakatani, victory would be the greatest upset in Japanese boxing history, propelling him into the pound-for-pound top three.

No matter the outcome, fans are guaranteed a spectacle. The Tokyo Dome will be electric. The world will be watching. Do not miss a second of the action. Set your alarms, buy the pay-per-view, and prepare for a war.

Inoue vs Nakatani start time: Saturday, 2 May, 8am BST / 3am ET. How to watch: ESPN+ PPV (US), Sky Sports Box Office (UK), Amazon Prime Video (Japan). Undercard: Takuma Inoue vs Ryosuke Nishida, Kenshiro Teraji vs Carlos Canizales, and more. This is the fight of the year. Be there.
