Oriental and Pacific Boxing Federation minimumweight female champion Mizuki Chimoto of Watanabe Boxing Gym pounded out an eight-round majority decision over South Korean Park Hye Soo and retained her title on Sept. 17 at Mielparque Hall Osaka.

It was the 28-year-old Chimoto’s second successful defense of the title she captured in June 2021 by edging Yuko Kuroki of YuKO Fitness Boxing Gym for the vacant title. Chimoto made her first successful defense of the title this May by decisioning Kaori Nagai of Shinsei Boxing Gym.

After the fight, in which there were no knockdowns, Chimoto said, ‘’I am glad that I was able to win. Ms. Park was stronger than I had expected. I need to have more experience.’’

With the victory, Chimoto extended her unbeaten streak to five, including a knockout. Meanwhile, the 34-year-old Park, the OPBF’s seventh-ranked flyweight, fell to a 6-9-3 win-loss-draw-tally with one KO.
