I'm so bad, I choose my favorite actresses mostly according to how they look, so superficial, but I really like all of their acting too.
Horikita Maki - She is cuteness in human form. I like her most in Hana Kimi and Atashinchi no Danshi. I wish she played more roles like this.
Aibu Saki - She is so pretty and her smile is gorgeous. I actually liked her acting best in Buzzer Beat, although her character is a really bia. I'd like to see her in more serious roles because she was cute in Zettai Kareshi but a little unconvincing.
Kuroki Meisa - She is stunningly beautiful. I loved her sweet innocent compassionate role in One Pound Gospel.
Kichise Michiko - She's got the whole cougar thing going on, and all I can say is Miss Kichise please take me lol. I love her acting in Bloody Monday, and Boss, and everything else I've seen her in. She always does a good job.
Inoue Mao - I was really impressed with her acting skills in HYD, and I think she is really cute in First Kiss
Ueno Juri - How she ever pulled off a crazy character like Nodame I'll never know, but she did it so great that I totally fell in love with her. I wanna see more rolls with her like this.
Erika Toda - I always really like her characters, especially in SPEC and Boss. I think she's cute, but she's not quite as cute as the others.
