I thought Kanjani8 is supposed to be the one who promoting this ecowhatever campaign?
Last year AKB48 had the CM too when Perfume was the one who being choosen.
and I remember AKB48 promoting DoComo around KAT-TUN's signal CM.
I'm lost D:
I shouldn't think too much when OkuAyakaMariko is in one screen though :D
Hurray for Oku's hair!!
