is a Japanese kickboxer. He competes in ONE Championship's bantamweight and flyweight division, where he is the former ONE Kickboxing Bantamweight World Champion.

Background Japanese-born Akimoto began his martial arts journey at the age of eight. He took up full contact karate and became a top talent over his years of training. Both of his parents were instructors in the Shichishu-Kai, but he was never forced to participate. It was not until he was involved in a fight at school did he decide to take up martial arts.

As his skills grew, he turned to competition. He did not stick with karate, and also competed in Muay Thai and kickboxing bouts. To get the most of his talents, Akimoto moved from Japan to Singapore to train at Evolve MMA and pursue a world title in ONE Championship.

Kickboxing career Akimoto got off to an incredible start to his professional career. He racked up 19 straight kickboxing victories that would lead him to be signed by ONE Championship.
