Ok as an Arashi fan I was looking for streams of Kouhaku live as well as Johnny's count down live on new yrs eve. And i was not very successful in finding good quality streams of those shows before midnight Japan time. I did however find this from a really nice person in an Arashi chat room.

Freshverse is a board that streams live Japanese stations. The host decides what channel is watched and when the channel changed but it is live from japan. Right now i'm watching the talent show that Matsujun co hosts on NihonTV called
"Showtime". For me this is an awesome find for the new yr. so if u don't mind watching raw stuff, from variety shows to dramas to anime and news the same time it Japan (live stream) come check it out. u have to register which takes a few seconds but imo it's totally worth it as a Japanese enthusiast!
