I'm about to quickly count down the top 50 album chart runs by non-Japanese female artists (Koreans or other Asians singing in Japanese also don't count).
This is based on the Oricon top 30 from January 1988 up until now.
Point system to score the chart runs is:
#1 = 60, #2 = 57, #3 = 54, ..., #10 = 33
#11 = 30, #12 = 28, #13 = 26, ..., #20 = 12
#21 = 10, #22 = 9, #23 = 8, ..., #30 = 1
Obviously this again rewards longevity more than impact, but it's the fairest way to compare albums from different years.
If you feel an album or artist is missing, you can request chart runs at the end and I'll look them up.
Here we go
