Help with ID of this perfect Japanese girl!

Got this off 4walled.org recently after searching under "asian". No tags, nothing from tineye and nothing from the thread about the most commonly asked for idols. Can anyone help?

She's got an absolutely perfect face and body.

Thanks in advance.

She looks like Sayumi Michishige

^ Close enough, but the girl in the picture is Mano Erina (真野恵里菜).

The picture is from the photo-book called "Mano Days".
