Such a sweet face... and, what, only three movies to date? At least her output has been very recent, so the odds are, there will be more of Haruka to cum. .
Can't tell in the pics but does she have a little mole on the right side of her upper lip?
If she does, then CodeGeek is right - Haruka Tachibana.
She also has another name Rinko Kuriyama (栗山凜子) under the "Mywife" series.
outdoorlife, you're right: It is her. If you go down on Sougouwiki page of Haruka Tachibana (http://sougouwiki.com/d/%b5%cc%bd%d5%b9%e1) you'll find the same photo as the first photo on the page you mentioned.
