used to be uncommon. David Cronenberg casting Marilyn Chambers at the lead in RABID (1976) was waaaay ahead of its time. it's one hell of a horror film and she's perfectly cast, track down a copy.
glad to hear Sora/Sola Aoi is doing TV but fans will want to catch her feature-film leading role:

IMdB has this irritating habit of listing Asian films under their transliterated titles. they call this one "Kyonyû doragon: Onsen zonbi vs sutorippâ 5" which i'm not gonna attempt to translate. the English title--BIG TITS ZOMBIE--is much more informative.
basically, Aoi and her co-strippers (including at least one other JAV star, sashimi the living fuck outta the living dead. and show their tits, not constantly, but more than a brief flash like some peek-a-boo Hollywood star. why not? what's wrong with tits? and what's wrong with combining them with zombies??
Japan has been making over-the-top gore/irony flicks for awhile now, my favorite is still TOKYO GORE POLICE (2008) which manages to skewer Japan's corporate culture along with extreme fake-violence.no pornstars, but does star Eihi Shiina from Takashi Miike's astounding 1999 film AUDITION (

Sora Aoi has been starring in various mainstream and "pink" (softcore) films since '04:

gotta love stroke-flicks with titles like "Yeah! Nurses!! Max Max 4 Hours"...that pixelated censorship is idiotic though.
