Yasuda and Ishikawa are pregnant so they both gets a pass for showing up. Iida just had a baby in September so she also gets a pass.
Yuko, Nacchi, Fujimoto and Yoshizawa have small children and as far as I can tell, Nacchi and Miki feel semi-retired.They aren't active by any means, both removing themselves from M-Line a year ago. Yuko, I think still does some TV work but not outside of where she lives. Not sure about Yoshizawa, she's still active but not super active.
Tsuji's got kids, but they aren't really babies anymore, I think her youngest is 4. So she's in a place where she can do stuff and not be tied down with a baby.
Mari , I could care less about. She's dead to me. xD
The only one I don't know why she didn't show up is Risa. I'm assuming she may just have had some scheduling issues. She is an active theater girl so she might have been involved with that.
So basically of all the OG still left in Up-Front. I can only see a handful that could handle performing.
Nacchi had a couple albums in the last 3 years though hasnt she?
I haven't heard of any Nacchi albums since the last one I bought, "Natsumi Abe: Best Selection – 15 Shoku no Nigaoe Tachi ," which was in December 2008. Has she released new albums since then? If so, what label? And why haven't I heard of them?
