I only know bits and pieces.
Nancy Kumi has more rumours about her than any other Japanese wrestler I know of. It seems she was a hostess at some point, though I don't know when. The last I saw of Kumi was a picture of her and Fujimi at the memorial of what would have been Jackie Sato's 50th birthday. Apparently, Nancy Kumi nursed Jackie while she was dying.
Most of the girls tried careers in entertainment after retiring -- acting, singing, modelling, comedy, that type of thing. None of them were particularly successful. Dump & Omori had brief success as comedians & I think Mimi Hagiwara kept her idol act going for a few years, but the majority of girls got married & most of them have kids now. IIRC, Kayama and Kumano were at Jaguar's 30th anniversary show. Ikeshita got married after she retired. They're all oba-sans now. Yumi Ogura is gonna have a baby soon, which is cool. And I think Jumbo Hori will be a grandmother soon. Maki Ueda tried acting for a while, but she runs a restaurant somewhere outside Tokyo these days.
