I'm going to compile Ayu's RIAJ certifications here as sourced from
this page and
this page so that there's no real confusion as to how much a ringtone sold or how much something shipped... or something.
NOTE: THERE ARE SINGLES MISSING FROM BETWEEN 1998 - 2003. This is due to RIAJ tracking in like 2003 onwards.. or something. Or perhaps they just don't want to reveal those CDs' certifications?
Terms:
Million -> 1,000,000+
Triple Platinum -> 750,000+
Double Platinum -> 500,000+
Platinum -> 250,000+
Gold -> 100,000+
