Takuma Inoue proved too fast, too sharp and too fresh for an ageing Kazuto Ioka on Saturday at the Tokyo Dome.Inoue dropped Ioka twice en route to a lopsided unanimous decision win on the undercard of his older brother, Naoya’s, Japanese super fight with Junto Nakatani.AFPInoue dropped Ioka in rounds two and three[/caption]The three judges sided with the younger Inoue brother by margins of 119-107, 120-106 and 118-108.In victory, Inoue retains his WBC bantamweight title and denies future Hall of Famer Ioka from becoming a five-weight world champion.A visibly emotional Inoue said post-fight: “It was a very intense battle from the first round to the third round, but it was very fun.“Thank you so much, Ioka, for fighting me.“He is a legend, and I have been looking up to him throughout my career.“Because of him, this fight was great, and because of him I am stronger than ever.”Inoue (22-2) then called for a unification clash with one of the other champions at 118lbs (Seiya Tsutsumi, Jose Salas Reyes, and Christian Medina).Ioka (32-5) is now 1-3 in his last four fights and may very well have made the final ring walk of his storied career.Story of the fightThe former pound-for-pound top 10 fighter looked every one of his 37 years as he was picked apart on the outside by Inoue.While Ioka was able to walk Inoue to the ropes, he rarely capitalised on the openings.View Tweet: https://twitter.com/hashtag/InoueNakatani?src=hash&ref_src=twsrc%5EtfwView Tweet: https://twitter.com/hashtag/InoueNakatani?src=hash&ref_src=twsrc%5EtfwThe difference in speed was clear from the opening bell as Inoue repeatedly snapped back Ioka’s head with ram-rodding jabs.In the dying embers of round two, a sharp right-hand counter and a follow-up flurry sent Ioka tumbling to the canvas.But Ioka made his way back to his feet to hear the final bell. Sensing his man was in trouble, Inoue put his foot on the gas in the third stanza and decked Ioka for a second time with a booming right uppercut. Ioka, once again, regained his footing and saw out the round.The rugged veteran rebounded well in the fourth and arguably nicked the round as Inoue eased off in an attempt to walk his adversary onto a finishing blow.However, from round five onwards, Inoue was back in control as he circled off the ropes and into the centre of the ring, peppering Ioka with sharp shots.MORE TO FOLLOW…Watch Boxing on DAZN*If you click a link in this boxout, we will earn affiliate revenueSign up to DAZN to access the definitive subscription for boxing fans.Upgrade to DAZN Ultimate from just £24.99/month, guaranteeing access to 185+ fights annually, a minimum of 12 pay-per-views at no extra cost, as well as every Lega Serie A match and other elite football access.Alternatively, DAZN Standard is just £15.99/month, with the caveat you will have to pay for pay-per-view events.Click here to sign up.
