Pancrase Flyweight World Champion Senzo Ikeda first began his martial arts journey with boxing, when he joined Dream Boxing Gym in an effort to overcome his own perceived weakness. He proved to be a talented pugilist, and made his professional boxing debut in 2003.

However, after compiling an undefeated 8-0 boxing record with two championships in Japan, Ikeda decided to retire and was left searching for a new challenge. Although he toyed with the idea of a boxing comeback, a friend introduced him to mixed martial arts, and it reignited his passion for competition.

Although he began his mixed martial arts career in disappointing fashion, Ikeda never gave up. After years of persistence, he eventually managed to develop his all-round game and began to flourish. Ikeda started to dominate his opposition and became known as one of the most feared strikers in Pancrase, eventually capturing the Pancrase Flyweight World Title to earn a place among the world’s best martial artists in ONE Championship.
