On April 8, 2009, it was announced at a press conference that the April 19 Ito Dojo show would be Hamada's final match in Japan as she had signed with Total Nonstop Action Wrestling. On August 6, 2009, Jeremy Borash announced on his Twitter page that Hamada would be starting with the company after the Hard Justice pay-per-view. On the August 27 edition of "Impact!", Hamada made her debut as a face defeating Daffney in a No Disqualification match. The following week on "Impact!" she and Sojo Bolt were eliminated in the first round of the Knockouts Tag Team Championship tournament by Tara and Christy Hemme, with Hamada afterwards hitting Bolt with the Hamada Driver. On the September 24 edition of "Impact!" she was assaulted by Alissa Flash while giving an interview. Flash proceeded to throw Hamada down some stairs, sparking a feud between the two. On the October 15 edition of "Impact!" Hamada defeated Flash in a Falls Count Anywhere match. On the November 19 and December 3 editions of "Impact!" Hamada beat Taylor Wilde and then Sarita, the Knockouts Tag Team Champions, with the Hamada Driver.
