I know it's not much information to go on, but the face is very clear and the gifs are good quality. I don't recognise her at all and none of the gifs contain any real information to help identification. I tried a few reverse image searchers to no success. http://38.media.tumblr.com/ec275f01f902b5b73ea17327c9cc3f5d/tumblr_nfilr8GilQ1ti729qo1_500.gif http://38.media.tumblr.com/9395fde75e4f766b6df0164af89fb408/tumblr_nfilr8GilQ1ti729qo3_400.gif http://33.media.tumblr.com/07bc5f42bab606535dd0cc22e13b1bf9/tumblr_nfilr8GilQ1ti729qo4_500.gif Thanks in advance.
I recommend to attach image always to your posts using the "Upload a File" button (at least if they are not too big size wise because there is a file size limit). After the successful upload you can include them into your post using the "Full Image" button.
First I thought she is maybe not active anymore. But it seems she did some movies not long ago this year. http://sougouwiki.com/d/%b1%e0%ba%e9%b0%c9%ce%a4 http://www.dmm.co.jp/mono/dvd/-/list/=/article=actress/id=1014650/ She changed her stage name: http://www.dmm.co.jp/mono/dvd/-/list/=/article=actress/id=1025579/
