Biography Nakai was born on October 22, 1986, in Matsuyama, Ehime Prefecture. She started training in judo at the age of three. She was ranked #5 in judo in all of Japan in middle school and #3 in senior high school. She graduated from Takanawadai High School (a Middle School attached to Tokai University) and later dropped out of Teikyo University.

Early MMA Nakai started fighting on October 1, 2006. She defeated Asuka Ito by TKO (technical knockout), after breaking Ito's nose at Pancrase 2006 Blow Tour.

Smackgirl On May 19, 2007, she fought against Kazue Matake in her first fight for the Smackgirl promotion and won the decision.

On September 6, 2007, she fought against Asha Ingeneri in Smackgirl and defeated her on round one, at 1 minute 3 seconds with an armbar.

On April 25, 2008, she defeated Kanako Takeshita at her final fight for the Smackgirl promotion.

Valkyrie On December 7, 2008, she fought against WINDY Tomomi at the 4th "Pancrase-ism"-sponsored event and won by TKO with a mounted punch.

Nakai had a year and two month-long gap before her next fight. On February 11, 2010, she played against Mizuho Sato at VALKYRIE 04, which was her first fight for the VALKYRIE promotion, and won by Kimura Lock.

On June 19, 2010, she fought against Megumi Yabushita at VALKYRIE 06 and won a 3–0 decision.

On September 26, 2010, she fought against Mayumi Aoki in the semi-final of the women's open-weight class first champion decision tournament of VALKYRIE 07, and won with an armbar.

On November 28, 2010, she faced-off again with Mizuho Sato in the women's open-weight first championship tournament final of VALKYRIE 08. Nakai defeated Sato by Doctor Stoppage, when it was suspected that Sato had fractured of the orbital floor of her left eye. This win also earned Nakai the Valkyrie tournament win.

On December 30, 2010, in the VALKYRIE-sponsored match of the "Battlefield - Soul of Fight" event held at the Ariake Coliseum, she fought Mika "HARI" Harigai and won by Keylock submission.

Return to Pancrase On September 4, 2011, Nakai fought Danielle West to a split-decision draw at "Pancrase - Impressive Tour 9". On December 1, 2012, Nakai would rematch Danielle West at "Pancrase - Progress Tour 14", with Nakai this time defeating West by unanimous decision.

Nakai faced Mayumi Aoki in a rematch at Pancrase Progress Tour 10 on September 1, 2012. The fight was part of the opening round of the bantamweight Queen of Pancrase tournament. Nakai defeated Aoki by TKO in the second round.

On December 1, 2012, Nakai faced Danielle West in a rematch for the bantamweight Queen of Pancrase title at Pancrase Progress Tour 14. She defeated West by unanimous decision to become the first bantamweight Queen of Pancrase. There was a good deal of controversy surrounding the bout however, as some journalists, and observers accused Pancrase of "fixing" the match. West came in 1 kg heavy for the fight and as a result Pancrase officials made her cut weight a second time on the day of the fight to prevent her from re-hydrating. Beyond a second weight cut they also informed her that no knees or chokes would be allowed. However officials failed to inform West that the rule would only apply to her, Nakai would have no restrictions. West was only made fully aware of this discrepancy mid-fight. Following the fight West was also informed that even if she had won the contest it would have been declared a draw or no-decision.

On May 11, 2014, she fought against Sarah D'Alelio in Pancrase and won the decision.

She fought against Tara LaRosa in Pancrase on September 29, 2013, winning a 2–0 decision.

UFC In 2014, Nakai made her move to the American UFC promotion. When Nakai began competing for the UFC, the organization did not have a women's flyweight division (-56.7 kg), so she had to compete at bantamweight (-61.2 kg). Her UFC debut took place at UFC Fight Night: Hunt vs. Nelson on September 20, 2014. Her opponent was Miesha Tate, who at the time was ranked second in the women's bantamweight rankings. Nakai would lose the fight by 0-3 decision and was the first loss in her MMA career. At UFC Fight Night: Hunt vs. Mir on March 19, 2016, she faced Leslie Smith and lost a 0–3 decision.
