Google translating Twitter says Ai Shinozaki but she looks nothing like her. Specifically, I cannot find a copy of this photo labeled Ai Shinozaki.
Somebody in the 2ch thread said Wrestler Kana (who I find hot but she doesn't look too similar)
There are currently 2.73 trillion photos of Ai Shinozaki. One of them is bound to look like OP.
