Well they don't do work outside Japan so it'll be less, considering they work INSIDE JAPAN ONLY.
I don't exactly get what you're trying to say. Firstly most of the income comes from outside work. I'm pretty sure the actual performers of a song, as long as they didn't take part in the creation of the song, get a meager 5-10% of the total profits made from the song. So it's not like I expect them to make millions through that.
Actual money lies in appearances- TV, magazines, concerts, etc. I know gravure doesn't pay very handsomely. So I'm not even surprised that the fashion queens topped. But these girls-individually and in group, have quite a few brand endorsement contracts so I'd just expect them to earn a little more based on that. Not more by leaps and bounds. I saw a list once according to which the top girls demand about 400,000 USD per CF. Even if they got to keep about 30% of that, considering the top girls all have at least 10 or more endorsements, they should be making more.
Also I'm still curious how Kasai, Sayaka snd Sae are on that list and are making as much as they are. Because of this, in my eyes,this list seems a bit questionable when it comes to legitimacy.
