The boxing spotlight is focused on the pocket rockets of the sport and the best pocket rockets on the planet at that, on Thursday, March 13, at Tokyo’s Ryoguko Kokugikan Arena. Three of the world’s best flyweights take to the ring in the Japanese capital. The headline bout on the Title Fight Tripleheader in Tokyo is the all-Japanese flyweight unification clash, with the WBC champ, Kenshiro Teraji, taking on the reigning WBA holder, Seigo Yuri Akui. Ring Magazine ranks Teraji and Akui as the 2nd and 3rd best flyweights in the world, respectively.
WBO flyweight king Anthony Olascuaga is also in action. The American is defending his belt against Tokyo resident Hiroto Kyoguchi. If that’s not enough, Shokichi Iwata and Rene Santiago Garcia go glove-to-glove for the WBO light flyweight crown, too.
It’s the start of a huge week for Tokyo sports fans, with Major League Baseball pitching off their 2025 regular season with the Tokyo Series, which sees the LA Dodgers take on the Chicago Cubs on Tuesday, March 18th and Wednesday, March 19th. Locals will be hoping that several homegrown baseball stars who ply their trade in the MLB will be in action, including Shohei Ohtani and Shota Imanaga.
Back to the top-of-the-bill boxing clash at the Kokugikan, and amazingly, Kenshiro Teraji will enter the ring for a 17th straight world title encounter. It’s a run of bouts that goes back to May 2017. This will be his second all-Japanese unification bout, as he also took on (and dominated) fellow countryman Hiroto Kyoguchi during their light flyweight title unification fight back in November 2022. Teraji may have celebrated his 33rd birthday at the start of the year, but he shows no signs of slowing down. ‘The Amazing Boy’ is currently on a 6-fight win streak, winning by stoppage in five of those clashes.
Teraji’s only career defeat to date came against Masamichi Yabuki, in September 2021, when he was still fighting as a light flyweight. But he showed resilience when roaring back six months later to avenge that loss. Teraji only moved up to flyweight last September, when he outclassed and stopped Cristofer Rosales at Tokyo’s Ariake Arena to become the WBC king. This, therefore, will be the first defence of that title. Though Teraji is four years Akui’s senior, he does have physical advantages over his opponent from Kurashiki. Teraji has impressive power, and his knockout win percentage stands at 63% compared to Akui's 52%. The WBC champ also has a height and reach advantage of an inch.
Like Kenshiro Teraji, Seigo Yuri Akui has also racked up a lengthy win streak. His second career loss came way back in 2018. Unlike Teraji though, the majority of Akui's triumphs were decision wins. Although Akui's confidence is high after nine straight victories, he will be wary of Teraji's punch power as both his previous defeats were by TKO. We last saw Akui in action, making the second successful defence of his WBA flyweight crown, on the same September card as Teraji’s win over Rosales. This time, the flyweight foes enter the ring together on the same card.
