Isami Kodaka
Makoto made her debut for Yoshihiro Tajiri's Smash promotion on December 24, 2010, at "Happening Eve", where she teamed with Isami Kodaka and Yusuke Kodama to defeat Chii Tomiya, Hikari Minami and Kushida in a six-person intergender tag team match, scoring the deciding pinfall over Tomiya. In her next Smash appearance on January 29, 2011, at "Smash.13", Makoto was defeated by former WWE wrestler, Serena. After the match, Makoto was attacked by Kana, Io Shirai and Mio Shirai, the trio known as Triple Tails, who had earlier attacked another one of Tajiri's protégés, Yusuke Kodama, after his match. The trio was eventually chased out of the ring by Tajiri. On April 30 at "Smash.16", Makoto teamed with Serena and Syuri to defeat the Triple Tails in a six-woman tag team match. On May 3 at "Smash.17", Makoto teamed with Tajiri in a three-way intergender tag team ladder match, contested for possession of the new Smash Championship and Smash Diva Championship belts, which had been stolen earlier by Michael Kovac. In the match, Makoto and Tajiri defeated the teams of Kovac and Lin Byron, and Hajime Ohara and Jessica Love to regain possession of the belts, which were then put up for grabs in separate tournaments.
