Sendai Girls' Pro Wrestling
On February 11, 2008, Nakajima entered a tournament to determine the number one contender to the JWP Openweight Championship. After winning only one of her four round-robin stage matches, Nakajima failed to advance to the finals of the tournament. On June 8, Nakajima defeated Tyrannosaurus Okuda at a JWP event to regain the JWP Junior and Princess of Pro-Wrestling Championships. Nakajima made her first title defense on October 12, defeating Sendai Girls' Pro Wrestling representative Ryo Mizunami. After a 196-day reign, she lost the titles to Hiroyo Matsumoto on December 21 at an event held by the Ibuki promotion. On February 21, 2009, Nakajima, teaming with Toujyuki Leon, received her first shot at the JWP Tag Team and Daily Sports Women's Tag Team Championships, but the two were defeated by the defending champions, Keito and Yumiko Hotta. On April 19, Nakajima was defeated by Saki Maemura in a singles match. Following the match, JWP sidelined Nakajima from in-ring action due to "poor health". On May 31, Nakajima officially quit JWP and three days later announced her retirement from professional wrestling, however, keeping the door open for a possible return down the road.
