#2 Megumi Fujii
Just like Miku Matsumoto, Megumi Fujii was a pioneer of Japanese WMMA. In fact, Fujii was a bigger name than Matsumoto.
Fujii started her career in 2004 and was unbeaten for six years. She won 22 straight fights and only went the distance on three occasions. Her undefeated run went all the way to the Bellator Tournament final for the inaugural 115 pound Women’s championship.

Unfortunately, she suffered her first defeat in that fight against Zoila Frausto Gurgel via split decision and also lost the chance to hold the Bellator title. Interestingly, Fujii was 36-years-old when she fought for the Bellator title.
She fought six times after this defeat and won four fights including one against Mei Yamaguchi who is a prominent name in ONE Championship these days. In 2013, Fujii decided to retire from the sport as her age was starting to catch up on her.
