Both KinKi Kids & Kanjani8 are having their own separate countdown at different places outside of Tokyo & in recent times , even SMAP & TOKIO don't really participate in them as frequent as before
It frankly didn't really surprise me there might/will not be any Johnny's Countdown cos if so , this would have been announced way back in Aug if not last month
Now is already mid Oct , it seems very late & you cannot expect ARASHI to perform live via satellite which they've done so for the past 2 years isn't it ?
