This ranking from Oricon lists the top 10 music artists in the Heisei era in terms of the number of CD singles and albums they have sold. As such, this does not include DVD sales which actually should bring in more money than CDs but tends to be lower in terms of number of copies sold because of its higher unit price.
Dates in brackets indicate when the CD single or album was released.
