Yabuki Defends IBF Flyweight Belt vs Miel Fajardo in Tokyo
Yabuki (20-4, 18 KO) meets mandatory challenger Miel Fajardo on November 26th, headlining a stacked Tokyo card of Japanese title action.

IBF flyweight champion Masamichi Yabuki has his next assignment locked in: mandatory challenger Miel Fajardo on November 26th in Tokyo. Yabuki (20-4, 18 KO) is one of the sharper punchers you'll find below 115 pounds, carrying an 18-KO haul into a defense against a challenger with genuine one-shot menace of his own.
This is a mismatch on paper and a coin-flip in the punch stats. Yabuki holds the credentials, but Fajardo (14-3-2, 12 KO) earned this shot the loud way — flattening Tobias Reyes with four knockdowns inside 65 seconds earlier this year. When you land that hard, nobody's asking about your record.
How Yabuki Got Here
After Kenshiro Teraji evened their series at 1-1, Yabuki went on a tear: six straight finishes. That run included stopping IBF light-flyweight titlist Sivenathi Nontshinga, then-unbeaten flyweight champ Angel Ayala Lardizabal, and Felix Alvarado (42-5, 35 KO) — a fighter nobody had ever put away — with a 12th-round knockout.
The streak ended against Rene Calixto last June, but not for want of violence. Yabuki dropped 'El Indio' twice and cruised to a decision. So the champion arrives as a rightful favorite, with the finishing rate to back it up and the durability question already answered.
The Rest of the Card
Tokyo gets a genuinely loaded night around the main event. WBA minimumweight champ Takeshi Ishii (12-1, 9 KO) defends against an opponent still to be confirmed — one reportedly grinding through a brutal cut after campaigning as high as heavyweight. Yabuki's brother, Masanori Rikiishi (17-2, 12 KO), features against Melchor Roda (10-6, 6 KO) in a clear step down in competition.
Rounding it out, recently dethroned bantamweight titlist Yoshiki Takei (12-1, 9 KO) takes a rebound bout against countryman Kenshin Oshima (9-5-1, 5 KO). It's a get-well spot, but Takei's lone loss means he needs a clean night to stay in the mix. The whole show hangs on one question: can Fajardo's power close the gap the résumés say shouldn't close.
