If I'm not wrong, voting ends on 1st December 2006 and the top artist (top 1 or top 3, I'm not sure) will be presented with an award by Kashu-Navi AND they will be performing at the annual Internet Music Festival. (I think, again. Sorry! This is what I gathered... if there's something wrong with my info please correct me)
So please support KAT-TUN and cast your votes HERE! You can vote again every hour. They're currently at 5th position in the artist ranking with SIGNAL at 4th and REAL FACE at 17th in the song ranking.
Edit: To vote, you see the left sidebar on the main page? There's a bright orange button with the words 投票 on it. Click on it and there you go ^_^
