As of December 2020, he is ranked as the world’s fourth-best active super-flyweight by BoxRec, and third by The Ring magazine and the Transnational Boxing Rankings Board. He is also ranked as the world's ninth-best boxer, pound for pound, by The Ring.Kazuto Ioka is the nephew of flyweight champion Hiroki Ioka. Kazuto asked his father to teach him how to box as a teenager. His father, Kazunori Ioka, would continue training him through his amateur and professional career. Ioka amassed a record of 95-10 as an amateur, winning six national high school tournaments along the way. He reached the semifinals of the 2008 King's Cup, an amateur boxing tournament held in Thailand, before losing to Amnat Ruenroeng. Ioka joined Tokyo Agricultural University, hoping to represent his country in the 2008 Olympics but he would fall short on the qualifiers.Upon failing to qualify for the Olympics, Ioka dropped out from college and turned professional in 2009. On April 12, 2009, he fought against Thongthailek Sor Tanapinyo, and won his debut via a third-round technical knockout. After this victory, he won six straight victories. After winning 5 fights, Ioka competed for the vacant Japanese light flyweight title. Ioka captured the national title by stopping Masayoshi Segawa in the final 10th round.In his next fight, Ioka won the WBC mini-flyweight title from Oleydong Sithsamerchai via a fifth-round technical knockout in the latter's seventh title defence at the World Memorial Hall, in February 2011. Sithsamerchai was knocked down twice over the course of his first professional loss. Ioka went on to defend his title twice in 2011, first against Juan Hernández, winning via unanimous decision (118–111, 117–111, 116–112), and then against Yodgoen Tor Chalermchai, winning via first-round technical knockout on New Year's Eve 2011.On 20 June 2012, Ioka met WBA champion Akira Yaegashi in a match that marked the first time two Japanese fighters had met to unify world titles. The fight took place at the Osaka Prefectural Gymnasium. Ioka defeated the WBA champion Akira Yaegashi via a unanimous decision (115–113, 115–113, 115–114). The two fighters exchanged hard shots throughout a tense, tactical fight. The fight ended with Yaegashi and Ioka trading combinations while looking for a knockout. From early in the fight, Yaegashi's eye was nearly shut. The ringside doctor performed several checks on it but Yaegashi was allowed to finish the fight. When asked whether the result would have been different unless he got swollen eyes, Yaegashi said "We should not think about it. There is no if's in boxing". The day after the fight, Ioka decided to move up a weight division.
