Fujioka has been one of the stars of female boxing, particularly in the East. She was a stand out amateur before turning professional in 2009 and quickly raced to a title, claiming the OPBF female Minimumweight title in just her 4th professional title. She would add the WBC female Minimumweight just 2 fights later, beating Anabel Ortiz for the belt. Having out grown the Minimumweight division Fujioka jumped up to Super Flyweight, battered Naoko Yamaguchi for the WBA female Super Flyweight title and then pursued more titles. Unfortunate she has, twice, lost in bouts for Flyweight gold but did claim the WBO female Bantamweight title in 2015 when she beat Hee Jung Yuh.
In the ring Fujioka is an aggressive fighter, who looks for the stoppage but can also box. A bit of a boxer-brawler if you will. She's tough, having take some serious bombs from Shindo Go last year, and determined. Unfortunately she hasn't shown her best outside of Japan, losing 2 of her 3 bouts outside of her homeland. Despite those losses, to Susi Kentikian and Jessica Chavez, Fujioka showed her ability and was competitive with both, and in reality the decision against Chavez was one of the worst in world class female boxing last year.
Whilst Fujioka is a proven fighter, with wins against the likes of Naoko Shibata, Anabel Ortiz, Naoko Yamaguchi, Mariana Juarez and Shindo Go the same cannot be said of Millan. In fact the Mexican has yet to score a major win at genuine world level, though has got some notable ones including a victory last year over Amira Hamzaoui. That win netted Millan the WBF female Flyweight title which she has defended once. When it comes to her most notable bout that was loss, with Millan being stopped by Esmeraldo Moreno in 2014.
Since her loss to Moreno fans have seen Millan go 8-0 (2), though mostly against very limited opposition. She did score a win in France, as mentioned against Hamzaoui, but fighting in Japan against a fighter like Fujioka is a massive step up.
From the footage of Millan she looks like a tall and rangy fighter but one who lacks in terms of skills and ring IQ, rarely setting up her punches and often looking more like a gangly fighter than a trained boxer, throwing looping open shots from outside of range. At the level she's been fighting at that's not been too much of a problem but against a fighter like Fujioka it will be a major issues.
Given what's available of both women it's hard to see anything but a win for Fujioka, in fact we'd be going with Fujioka to stop Millan in the middle rounds with the Japanese fighter simply breaking down Millan with her tenacity and power. If she does that, as we're predicting, then Fujioka will mark her name in the history books as the first Japanese fighter to become a 4-weight world chanmpion.
