Not to dis Japanese horror, but there are other countries which produce horror featuring nubile girls and copious amounts of blood. Hell, America is one of them, and recieves criticism for it from "serious" horror fans who think they are too good for gore and beautiful ladies.
Actually, Cannibal Holocaust is an Italian film which became one of the top 10 grossing films in Japan. It was so effectively gorey that there were rumors that the actors were really killed in the film.
