Good god... looking over his cv at Jpop Stop! has just convinced me that he does not have a room full of monkeys constantly typing out songs for AKB and SKE.
He has written for a few Johnny's groups (Kinki Kids most notably), the grandfather and grandmother of music (Yazawa Eikichi & Wada Akiko), comedy groups, Takada Junji, JERO's big breakthrough hit Umiyuki, EXILE, 'godfather' Go Hiromi, and those are only the ones I know!
He does not need the whole AKB thing, that's how much awesome he is. He probably smokes all those dollar bills you guys give him...
