I really agree with all the look-alikes oaxiac has mentioned. The Yuuka and Kanatomo one,
And I had always thought Sayumi and Mano Erina looked very much alike.. almost like twin sisters.
I also see the resemblance for Kojima Mako and Eri.
The Junjun and Miyazaki Yuka one is also agreeable.
And the moment I saw Kanon I thought she and Aibon looked reaaaally similar xD
Also the same for Linlin and Ayaka.
Miyabi and Fukuda Saki too, its actually kind of scary LOL
And definitely have to agree with the Shida Mirai and Masuda Yuka and Sudo Maasa one, thought of that one for a long time too.
And I can see where the Hannah Montana and Koharu one is coming from, but I also agree Sawajiri Erika looks similar with Koharu in some pictures.
I was watching AKB48 Senbatsu 2014 recently and I managed to screencap some members (Apologies I really don't know their name =/) and maybe it was just that screenshot but they really reminded me of some H!P members xD and also want to share some of the members I thought looked alike as well.
1.)
I thought she was Ishida Ayumi from Morning Musume. 14 when I saw her.. I was like.. What is Ayumi doing here in Senbatsu?? O______O {Ayumi in photo below}
2.)
This one I thought was Tokunaga Chinami from Berryz Koubou. I don't think I need to circle them to point out which one I thought looked like Chinami because it was like literal double in this screen
[Thought I might just add this, girl with green necktie bow looked alike to Yamamoto Sayaka (NMB48) in this picture] {Chinami in photo below}
3.)
I also have always thought Maeda Ami (AKB48) looked alike to Yajima Maimi (C-ute) but with thicker eyebrows. (Ami on left, Maimi on right)
4.)
Marius Yo (Sexy Zone) and Kudo Haruka (Morning Musume.14) they are like boy and girl ver. of each other o-o
5.)
Last one I'll post {for today maybe} is Tanigawa Airi (NMB48) I seriously think she gives off a Chisato vibe and that might be the reason she's one of my favourite member of NMB48 and in AKB48 fandom because Chisato is my goddess. And I used an old photo because it adds to the similarity
