WBA bantamweight champion Koki Kameda successfully defended the crown for the sixth time, winning a split decision over Panomroonglek Kaiyanghadaogym of Thailand on Sunday night in Osaka.
Koki, the oldest of the three Kameda boxing brothers, improved to a record of 30-1, including 17 knockouts. He is the only Japanese fighter to win titles in three weight divisions.
"I have nothing to say but sorry," said Kameda. "All these people gathered to watch me and all I could do is this. I wanted to end it with a knockout. I want to evolve and come back stronger."
