That's seiyuu Hayami Saori 早見沙織 doing the voiceover in this Japanese TV spot for the current movie "Lovely Bones." At least that's what it sounds like to me and to a couple of posters on 2channel.
Hayamin, 18, starred last year in the animes Eden of the East and Sora no Otoshimono, and has released several songs connected with the latter. She is currently starring in the film release of Eden of the East.
Check out my earlier posts about her.
