Japanese boxer Umi Ishikawa is the WBC female interim minimumweight champion. She achieved this feat on May 3, 2024, in Pathum Thani, Thailand, by defeating Thailand’s Sothita Sitthichai with a second-round knockout. Born on March 21, 1984, in Tokyo, Ishikawa is currently 41 years old, an uncommon age to shine in the lighter divisions, where youth typically dominates. Standing about 5'2" with an orthodox stance, her professional record shows power and determination: 12 wins, 10 of them by knockout, and 3 losses.

 

Her professional career began in 2016, and since then, she has been known for her offensive style, which allowed her to quickly climb the ranks in the Asian scene.

 

In May 2023, she got a quality win in the atomweight (102-pound) division, knocking out Nitinart Plabplerng. In August of the same year, she moved up a weight class and in her second fight at 105 pounds, she defeated Sitthichai with a third-round KO. She has not fought since then.

 

She is hoping for a fight against the current WBC full champion, Costa Rica's Yokasta Valle.
