A Bitter Bantamweight Rematch: Riku Masuda vs. Seiya Tsutsumi
At the forefront of the November 29th card is the WBA bantamweight title rematch between reigning "world" champion Riku Masuda, boasting an 11-1 record with 9 coming by way of knockout, and former titleholder Seiya Tsutsumi, who enters the ring undefeated at 13-0-3 with 8 knockouts. The two fighters share a significant professional history, having previously collided in 2023 when both were rising prospects carving out their paths in the domestic ranks. On that occasion, Tsutsumi earned a definitive unanimous decision victory over Masuda, establishing his technical superiority and tactical discipline at the time.
The path back to this squared circle encounter has been uniquely convoluted, navigating the complex politics and shifting landscapes of the sanctioning bodies. Yet, the reality of the matchup brings together two aggressive, heavy-handed finishers whose previous rivalry guarantees fireworks. Tsutsumi, who arguably holds a legitimate claim to a broader world title opportunity given his previous reign and undefeated status, finds himself fighting for a version of the belt he never technically lost inside the ring. For Masuda, the bout represents an opportunity for career redemption, a chance to avenge his lone professional defeat, and a definitive statement to the bantamweight division that his current championship status is fully earned. Given both men’s propensity for throwing caution to the wind and hunting for the stoppage, fans and pundits alike are anticipating an absolute war from the opening bell.
Kenshiro Teraji Moves Up to Defend Against Jassiel Ramon Amador Gamez
Moving three pounds south to the super flyweight division, multi-weight world champion Kenshiro Teraji continues his campaign in a heavier weight class as he makes his first title defense against hard-hitting Mexican contender Jassiel Ramon Amador Gamez. Teraji, an elite technician and seasoned champion with a stellar 26-2 record featuring 16 knockouts, has cemented his legacy as one of Japan’s premier modern fighters. However, questions linger about whether the decorated veteran has begun to lose a step as he enters the latter stages of his prime, making his next outing all the more intriguing.
His challenger, the 25-year-old Amador, brings an unblemished 15-0-1 record with 13 knockouts into the ring, showcasing devastating power that has overwhelmed previous opponents. Despite his impressive regional resume, this bout represents a massive step up in competition and environment for the young contender, marking his very first professional appearance outside of his native Mexico and only his second fight outside his home state of Baja California Sur. While boxing history is rich with unheralded Mexican knockout artists traveling abroad to cause major upsets, Teraji’s veteran savvy and championship pedigree will serve as the ultimate test for the ambitious challenger.
David Jimenez Faces Seigo Yuri Akui Amid Sanctioning Controversy
Rounding out the championship tripleheader in the 115-pound division, WBA champion David Jimenez (18-1, 12 KOs) is set to put his title on the line against former flyweight titlist Seigo Yuri Akui (23-3-1, 13 KOs). Fight fans will fondly remember Akui for his sensational, action-packed battle against Teraji last year, a contest that rightly earned Fight of the Year consideration for its unrelenting pace and sheer drama. Akui’s transition and performance at the weight class ensure that Jimenez will face a formidable, battle-tested opponent.
However, the matchup has not arrived without considerable controversy behind the scenes regarding the sanctioning body’s handling of mandatory obligations. The World Boxing Association had originally ordered Jimenez to make his mandatory defense against top challenger John "Scrappy" Ramirez. In a controversial turn of events, the sanctioning body subsequently reversed course by granting Jimenez a "special permit" to take on Yuri Akui in a voluntary defense instead.
In its official statement justifying the decision, the WBA claimed it holds the discretionary authority to modify mandatory defense deadlines and grant special permits under "justified circumstances." Notably absent from the press release, however, was any explicit explanation detailing what those specific justified circumstances actually were. While the sanctioning body’s mandate dictates that the winner of the Jimenez-Akui bout must face Ramirez within 120 days, observers and industry insiders remain skeptical, pointing to the WBA’s explicitly stated authority to further modify mandatory defense deadlines at will. As the fighters finalize their training camps for November 29th, the action inside the ring at the Ryogoku Kokugikan will look to overshadow the bureaucratic friction happening outside of it.
