I came to know it since when I was little I liked Mini Moni-san.
My dad is a Morning Musume fan, and so I got to know them when he took me to a live.
Suzuki Airi-san appeared in a drama, and I thought she was cute so looked her up and got to know it through that.
I found it by chance on a video site.
I got to know it through Buono!-san singing the theme song for the anime "Shugo Chara!"
I just knew it.
I happened to go to a Morning Musume-san release event which was at my local mall, and when at the handshake they asked me "How old are you?" and said "It's not too long before you'll be able to audition!"
I got to know it through a friend's recommendation.
