Everyone did their job at the scale to ensure the final two title fights of 2019 proceed as planned.

Kazuto Ioka and Jeyvier Cintron both made weight for their New Year’s Eve headliner, which takes place at Ota-City General Gymnasium in Tokyo, Japan. Ioka weighed in right at the 115-pound divisional limit for the first attempted defense of his junior bantamweight title, while Puerto Rico’s Cintron checked in at a fighting fit 114.75 pounds for his first career title fight.

Ioka (24-2, 14KOs) claimed a 115-pound title with a 10th round knockout of Philippines’ Aston Palicte this past June in Chiba, Japan. The win saw the 30-year old become the first-ever male boxer from Japan to claim titles in four weight divisions, joining Naoka Fujioka as the second-ever Japanese boxer to accomplish the feat.

The feat was accomplished on the second try for Ioka, who came up just short in a 12-round split decision defeat to Donnie Nietes for the same title last New Year’s Eve in Macao. Previous title reigns have taken place at strawweight, junior flyweight and flyweight.

Cintron (11-0, 5KOs; 1ND) emerged as the mandatory challenger following a decision win over Koki Eto in their rematch this past August. The bout came barely two months after their controversial first fight this past May at Osceola Heritage Park in Kissimmee, Florida, in which Cintron—a two-time Olympian for Puerto Rico—was initially deemed a 1st round knockout victim, only for replays to show the sequence was caused by a foul, changing the verdict to a No-Decision.

Their second fight took place in the very same venue, with Cintron scoring a decisive points win to emerge as the top contender to Ioka’s title.

The evening’s chief support pits three-division and reigning flyweight titlist Kosei Tanaka (14-0, 8KOs) in a voluntary defense versus China’s Wulan Tuolehazi (13-3-1, 6KOs).

Both fighters came in right at the 112-pound flyweight limit.

Tanaka attempts the third defense of the title he claimed in a 12-round thriller over countryman Sho Kimura last September in what landed as the BoxingScene.com 2018 Fight of the Year. The win also helped him match Vasiliy Lomachenko’s record of becoming a three-division titlist after just 12 pro fights. The 24-year old all-action hero enters this fight on the heels of come-from-behind 7th round knockout of Puerto Rico’s Jonathan Gonzalez this past August in his hometown of Nagoya, Japan.

Tuolehazi comes in riding an 11-fight unbeaten streak after stumbling out to a 2-3 career start. Tuesday’s bout marks his fifth of 2019, though stepping way up in competition against a bubble pound-for-pound entrant as he enters his first career title fight.
