Heavily rumored to be taking place on December twenty-seventh, on the Inoue vs. Picasso undercard (along with Kenshiro Teraji vs. José Francisco Rodríguez Tamayo Jr.). It would be contested at super bantam - where Cárdenas is coming off a failed challenge of unified champion Naoya Inoue - with Nakatani vacating his WBC & IBF titles at 118lbs to move up and debut at 122. Despite being the "smaller" man (starting his career at minimumweight, and having fought in all five divisions through bantam, but by and large a majority at flyweight; Cárdenas on the other hand only ever made the bantamweight limit once, barely, by 4oz, and has fought as high as lightweight) - the Japanese southpaw will have a 3" height and 1½″ reach advantage over the San Antonio native. This reads very much like an opportunity for Nakatani to prove himself against Inoue's par, and potentially set up a superfight between the undefeated countryman in 2026.
This one is super interesting, as Nakatani bears a lot of similarities to Inoue (rising up through pretty much all the same weight classes, being exposed to a variety of styles from around the globe despite primarily fighting at home in Japan, and they're in the same neck of the woods as far as power, hand speed, and explosiveness but with both also tempering all those natural gifts with very technical ring craft courtesy of their coaches, respectively Rudy Hernández and Shingo Inoue). Inoue found out quickly once the bell rang that Cárdenas, despite not having a particularly high rate of stoppage, is a bull-strong natural 122lber (if not honestly a natural featherweight). Cárdenas managed to not only drop Inoue in the second round, but hurt him a couple of additional times before things started to unravel for him in the seventh and fateful eighth. I'm very curious to see how Nakatani's punches affect Cárdenas, and vice-versa, in comparison with The Monster.
It will be interesting how a Cardenas who isn't underestimated by his opponent would do. Not taking credit away, but you can't deny Cardenas was severely underestimated until his last fight.
That wouldn't even come close to removing any credit. If Inoue underestimated his opponent, despite being a professional boxer, that wouldn't alter any credit given to Cardenas for the successes he had in the fight.
If that happens, ironically it probably doesn't raise Cardenas' value as much as it should and it would just lower Nakatani's value. Savage KO win by Nakatani within 6R - raise Nakatani's value and hype up the anticipation for Inoue-Nakatani next year, possibly reverse the odds of who wins. A late KO win or a wide decision by Nakatani - prove Cardenas success against Inoue wasn't a fluke and that Cardenas has what it takes to be fighting at the top tier of 122. Despite consecutive losses Cardenas would still have value as a potential champion to be. Inoue-Nakatani hype stays the same. Struggle or close decision by Nakatani - lower Nakatani's value and lessen the anticipation for Inoue-Nakatani next year. I actually think something like a solid 10R KO win would be the best case for me who is looking forward to Inoue-Nakatani the most.
Inoue is fighting MJ in September. Then Picasso for December. Disappointing because I thought Inoue was gonna fight Nick Ball next after MJ.
They are trying to build up the Inoue-Nakatani more to see how Nakatani does against the same guy who was competitive with Inoue. Not too crazy about this match up honestly. Would rather see Nakatani against Bam where the winner of that fight takes on Inoue. That would be a much more significant match up leading up to a fight with Inoue.
I'm not sure that Naoya Inoue will be at 126 lbs (Feathweight) until April / March 2026. Hideyuki Ohashi said that Naoya Inoue will fight Junto Nakatani on March 2026 and the fight is probably at 122 lbs (Super Bantamweight).
