We probably won't get any official confirmation on Kouhaku until the end of the month, but KARA are confirmed for Best Hits Kayousai on Nov.24 (http://www.ytv.co.jp/besthits/artist/2011_index.html) and FNS on Dec.7 (http://www.fujitv.co.jp/FNS/index.html).
FNS and Music Station Super live are my favorite end of the year shows. I'm super excited they are going to FNS this year.
