Were Erika Nagai, Shinobu Ayukawa and Chiharu Miyama really martial artists?

Question

I would like to know if hard to find now japanese AV stars Erika Nagai (Saori Fujimoto), Shinobu Ayukawa (Eri Matsui) and Chiharu Miyama were actually martial artists or if it was all nothing but publicity from the Soft On Demand company. Wikipedia is not clear on them, and it seems Shinobu/Eri is actually a judoka, as in some japanese board they said she was part of high school tournaments. Anyway, can anyone help according to background info or by analyzing their moves? Thanks.

Answer 1

LOL-Japanese schools have judo, kendo, karate, kyudo, etc. clubs for their students, and participation in at least one club (not necessarily budo) is usually mandatory. So the fact that a given AV star was on the judo team etc., in high school is unremarkable. Obviously though, pornographers are not the most reliable people.
