One of MMA’s most accomplished female fighters, Megumi “Mega Megu” Fujii, now has an opponent for her retirement fight at Vale Tudo Japan 3rd on October 5th in Tokyo. Fujii will conclude her storied career when she takes on former Bellator rival Jessica “Jag” Aguilar in a rematch on the card.

VTJ officials announced the matchup today. Fujii, who opened her career with 22 straight victories, announced plans for her retirement in June. She most recently defeated “V.V” Mei Yamaguchi at VTJ 1st in December. Her opponent, Aguilar, has won six straight and defeated Fujii in May 2012.

Fujii (26-2-0) has been a staple of the women’s pound-for-pound rankings throughout her career, which dates back to August 2004. The submission specialist has finished 20 of her 26 conquered opponents and she holds victories over a who’s who of the lighter women’s weight classes. In 2010, Fujii fought through serious injuries in order to compete in the Bellator 115-pound women’s title tournament. She advanced to the finals before dropping a contentious decision to Zoila “The Warrior Princess” Gurgel.

Since the loss to Gurgel, Fujii has won four of five fights. Her second defeat also came in controversial fashion inside the Bellator cage when she was outpointed by Aguilar at Bellator 69. In an action-packed, back-and-forth bout, Fujii rebounded with a close Unanimous Decision win over Yamaguchi on December 24th. She now competes one final time before stepping away from MMA competition.

Aguilar (15-4-0) currently stands atop the women’s strawweight division thanks to her close win over Fujii. She has not lost since September 2010 when she dropped a controversial Split Decision to Gurgel in the semi-finals of the Bellator tournament. After defeating Fujii, Aguilar sat out for ten months before returning in March at Bellator 94. In an uncharacteristically slow performance, Aguilar eked out a Split Decision win over “Little” Patricia Vidonic in a bout that many felt that Vidonic had won.

Both Fujii and Aguilar will have something to prove in their rematch next month. Fujii looks to avenge one of her two contentious defeats before stepping away from the sport, while Aguilar sets out to prove that she is the undisputed top female strawweight in MMA today.

Vale Tudo Japan 3rd takes place on October 5th at Ota City General Gymnasium in Ota, Tokyo, Japan.
