yeah, the whole debut single thing doesn't apply to K8. i think it's because JE didn't really put that much effort into K8's debut. they were only to debut in Osaka, but then it went nationwide too. i think if you watch Ohkura's SCP appearance he talked about K8's debut, and he compared K8's debut with Arashi's debut. K8 only got a conference room, while Arashi got a cruise ship in Hawaii. or something like that.
yeah, i think the other JE groups the debut single doesn't equal best-selling single are Tackey & Tsubasa and SMAP. i'm pretty sure the rest of JE's best selling singles are their debut singles (SMAP & beyond~ of course. i don't know about the previous groups like Hikaru GENJI, etc. lol)
AWESOME, AWESOME SALES FOR K8!
i'm really proud of all their success!
HAPPY BIRTHDAY SEXY OSAKA MAN~
i love you so much to you~!
