Kaori Yoneyama
On January 25, 2009, Toujyuki Leon was finally able to defeat Kaori Yoneyama in a singles match, pinning her with the "Captured Buster". On February 8, Toujyuki Leon and new tag team partner Arisa Nakajima defeated Kazuki and Sachie Abe to become the number one contenders to the Daily Sports Women's and JWP Tag Team Championships. They would receive their shot at the titles on February 21, but were defeated by Keito and Yumiko Hotta. On April 19, Toujyuki Leon defeated visiting freelancer Ayumi Kurihara in a high-profile singles match. On September 6, Toujyuki Leon and Kaori Yoneyama faced each other in yet another singles match, this time to determine the number one contender to the JWP Openweight Championship. Yoneyama would go on to win the match, avenging her loss the previous January. The following month, Toujyuki Leon got involved in a storyline, where she aligned herself with other JWP wrestlers to defend the promotion against members of the NEO Japan Ladies Pro Wrestling-based Passion Red stable. One notable match in the storyline saw Toujyuki Leon defeat Passion Ray in a singles match on December 13 at "JWP-Climax 2009". On January 10, 2010, Toujyuki Leon announced that she was shortening her ring name to just Leon, before defeating Passion Hotty in a singles match. On June 13, Leon wrestled her tenth anniversary match, where she and Kaori Yoneyama defeated Aja Kong and Akino. On September 26, Leon formed the Shishi no Ana ("Lion's Hole") stable with Basara and Misaki Ohata. On October 27, Leon represented JWP in Sendai Girls' Pro Wrestling's Joshi Puroresu Dantai Taikou Flash tournament, a single-elimination tournament, where different "joshi" promotions battled each other. In their first round match, Team JWP, which also included Command Bolshoi, Hanako Nakamori, Kaori Yoneyama and Kayoko Haruyama, defeated Team Pro Wrestling Wave, which included Gami, Moeka Haruhi, Shuu Shibutani, Toshie Uematsu and Yumi Ohka. The semifinals of the tournament were contested in six woman tag team formats, which led to Leon being sidelined from the match, where JWP representatives Kayako Haruyama, Nana Kawasa and Tsubasa Kuragaki were eliminated by Team Sendai Girls' Hiren, Kagetsu and Meiko Satomura. On November 27, Leon took part in an independent event produced by Passion Red, where she defeated Natsuki☆Taiyo to win the NEO High Speed Championship, her first title in four years. When NEO Japan Ladies Pro Wrestling folded the following month, the title was renamed the High Speed Championship.
