Panty peeks in VOLTES V?

I remember when I was a kid, I used to watch Western type cartoons (mostly done by Hanna-Barberra).
But when “Voltes V” came marching in on Philippine Television, I was hooked beyond belief; there were elements in the show that’s totally different from U.S. cartoons: Sword fights, intense drama and human sufferings, real death and destruction stuff.

Another thing that I noticed was the fearless showing of female underwear in the cartoons.
I really don’t understand why most Japanese animes from Voltes V’s times (And even so in the present) had this fetish on girls panties (they’re predominantly “white”.)
But one thing is sure, American cartoons in those times never shows what their female characters wear beneath their skirts, the Japanese approach was more radical and I thought, this method was aimed at younger male viewers. (Or the “panty” thing in Japan is just as natural as placing scripts on the characters and was not even a big deal for the viewers…)
Voltes V was not exempted in this “panty showing rule”: There are episodes where the character Megumi has to dodge a whip attack from the Ippei character. Doing so, her skirt flares up, showing her undies.

Another episode (Jamie’s dream) shows Megumi in a hurry, and she starts to put on her boots. The frame camera is in an angle where
The viewers could have a scant look of her panty-covered pubic area.
