Kenshiro Teraji and Seigo Yuri Akui will meet in a flyweight title unification fight on Thursday, March 13, at Ryōgoku Kokugikan Sumo Arena in Tokyo, Japan. Teraji’s WBC title and Akui’s WBA strap will both be on the line.

Teraji, 24-1 (15 KOs), enters his 17th consecutive world title fight, an eight-year run that includes two light flyweight title reigns. In March 2022, he avenged his only pro defeat by knocking out Masamichi Yabuki in three rounds. Teraji knocked out Cristofer Rosales in October to capture the vacant WBC flyweight world title.

Akui, 21-2-1 (11 KOs), beat longtime champion Artem Dalakian by unanimous decision in January 2024 and followed up the victory with decision wins over Taku Kuwahara and Thananchai Charunphak later that year.

Teraji-Akui tops a world title tripleheader that also features flyweight Anthony Olascuaga making his second WBO title defense against former two-weight world champion Hiroto Kyoguchi and Japanese standout Shokichi Iwata defending the WBO light flyweight strap against Puerto Rico’s Rene Santiago.

In 2023, Teraji stopped Los Angeles native Olascuaga, 8-1 (6 KOs). Last July, in Olascuaga’s second flyweight bout, he knocked out Riku Kano in three rounds. Olascuaga made his first defense in October with a first-round stoppage over former world champion Jonathan Gonzalez.

Kyoguchi, 19-2 (12 KOs), attempts to become a three-weight world champion and looks to recapture a world title more than two years removed from a knockout loss to Teraji in a light flyweight title unification battle.

Iwata, 14-1 (11 KOs), has won five straight, including last October’s third-round stoppage of Jairo Noriega. Santiago, 13-4 (9 KOs), is making his second attempt at a world title. He lost a decision to Jonathan Gonzalez in March 2024 before rebounding with a one-sided decision over Ricardo Astuvilca that October.

The three fights will stream live and exclusively on ESPN+ in the U.S. starting at 4 a.m. ET/1 a.m. PT.
