Junto Nakatani and David Cuellar quickly sized up each other and then offered the other a fist bump before they went their separate ways.

The amicable stare down was the last time that the pair of unbeaten boxers will meet before fight night. They both came in under the 118-pound bantamweight limit for their scheduled 12-round WBC title fight. Nakatani was 117 ½ pounds, while Mexico’s Cuellar weighed 117 ¼—his lightest weight in more than two years.

The two will square off this Monday, for Nakatani’s WBC bantamweight title. ESPN+ and Amazon Prime-Japan will air their scheduled 12-round bout live from Ariake Arena in Tokyo, Japan.

Nakatani (29-0, 22 KOs) will attempt the third defense of his current title reign. The Ring’s No. 1 bantamweight and No. 9 pound-for-pound entrant is a three-division titlist who enters his ninth career title fight.

The bout marks a rare fight where the 5'8" southpaw will see eye-to-eye with an opponent, never mind the slightly shorter fighter.

Cuellar (28-0, 18 KOs), who stands at 5′ 8½″, attempts his first bid at a major belt. The Ring’s No. 8 bantamweight also fights abroad for the first time in a career nearing eight years. His previous 28 contests have all taken place in his native Mexico.

The evening’s lone other title fight also takes place at bantamweight. Seiya Tstusumi (12-0-2, 8 KOs) risks his WBA belt against countryman and former flyweight titlist Daigo Higa (21-3-1, 19 KOs).

Tokyo’s Tsutsumi, The Ring’s No. 3 bantamweight, was right at the 118-pound divisional limit ahead of his first title defense. Higa, No. 9 at 118 by The Ring, weighed 117 ¾ pounds in his second crack at a bantamweight belt. He came up just short in a twelve-round thriller against unbeaten countryman Yoshiki Takei last Sept. 3 at Ariake Arena.

Monday’s title fight is a rematch of their Oct. 2020 meeting, which ended in a ten-round majority draw. Tsutsumi has since won seven in a row, including a twelve-round, unanimous decision over Takuma Inoue (20-2, 5 KOs) to win the WBA belt last Oct. 13, also at this venue.

Also on the show, Tenshin Nasukawa (5-0, 2 KOs) embraces his biggest risk to date as a pro boxer. The wildly popular former kickboxer faces former WBO bantamweight titlist Jason Moloney (27-3, 19 KOs), The Ring’s No. 7 contender at the weight.

Both fighters weighed in right at the 119-pound contracted limit for their scheduled 10-round non-title fight.
