That 13-Year-Old Fighter Just Beat Her 34-Year-Old Opponent — Replay!

In the history of MMA, there are plenty of examples of weird and bizarre events that take place in the sport in Japan.

JEWELS was at one time the premiere organization for women’s MMA in Japan. However, in Dec. 2011 a 13-year-old girl fought a 34-year-old woman at one of their events.

While it may seem odd and even cruel for a 13-year-old girl to fight a grown women, it took Yukari Yamaguchi just over one minute to submit her much older opponent with an armbar.

To this day, Yukari Yamaguchi has yet to lose a fight. She even has a shoot boxing win over former ONE Championship title challenger Mei Yamaguchi.
