According to Japanese sources, the convention probably started with Machiko Hasegawa's popular manga Sazae-san, whose character designs for Wakame Isono incorporated an improbably brief hemline.

Western-style clothing (including women's underwear) gained popularity in the post-war period, reinforced through numerous media outlets—magazines, newspapers, films, journals, and comics.
According to architectural historian Shoichi Inoue, the practice of "scoring" a glimpse up young women's skirts became extremely popular around this period; "Magazines of the time have articles telling the best places where panties could be viewed".
[10] In 1969, the Japanese oil company Maruzen Sekiyū released a television commercial featuring Rosa Ogawa in a mini-skirt that gets blown up by the wind and her lips forming an 'O' in surprise.
Artists working for the pay-library system had already pioneered the depiction of graphic violence, and had proudly declared that they were drawing gekiga ("drama pictures"), not mere comics.
