Aah I've been a JE fan since around 2004. The first group I really fell in love with was KAT-TUN since I was following the Gokusen Dramas back then...
After that gradually came NewS and then the Junior Groups (Yax3, Kis-my-Ft2, ABC, JJExpress) and Kanjani 8 and Arashi and well, I like a lot of boys in the Jimusho now =3 But I think I can say that my all time favourites are definitely KAT-TUN and Kis-my-Ft2. And I'm a happy fangirl since Kis-my-Ft2 and ABC are going to have their FIRST OWN CONCERT in the Yokohama Arena this October!!!
About HEY!SAY!JUMP... I used to not like them a lot because I was still sad that groups like JJE and Yax3 disbanded because of that and that people started disappearing (like Ayukawa Taiyou) and yeah... but recently I've gotten over that 'grudge' and I've come to the decision that I really just dislike Nakajima Yuto in that group and that I have no interest in Morimoto Ryoutarou... so I'm fine with the rest of the group... I prefer BEST over 7 though...which is probably easy to understand because of my age... *doesn't want to be a pedophile yo!*
As for Golf/Mike... unfortunately I missed their meet/greet event when I was in Japan...but since I'm a member of the International Fanclub and help with maintining a forum and webpage... I got a signed CD and Uchiwa nonetheless! =D *happyness* The club has also been having projects for presents for the 2 and a video featuring all international fans has been presented to Golf and Mike before their concert last year (it was also shown on TV afterwards, at least some snippets). It was actually supposed to be played during the concert as a surprise but the quality was too bad ^^; and uhm...some of our presents even appeared on Thai TV! When Golf and Mike were visited by reporters at home and showed their ROOM full of fan presents =]
