AVEX is just bad with promotion in general nowadays, have you seen their youtube account? They promote the crappiest **** there, and some really meh singers, they don't come up with great numbers like koda kumi, BoA and Ai Otsuka anymore, just plain boring generic forgettable looking singers.
And of course, many of these singers don't even make it into ORICON
Just ridiculous.
It seems like they are relaying on their Kpop acts atm.
