Yes, you have read very well, this Japanese crime flick looks like an Italian one from the seventies; I mean a very macho like movie where women are treated like cattle, beaten like dogs, even whiplashed OK, Japanese films have the reputation to be mainly for men, but not at this scale, in this manner. Many nude scenes in this feature where it is question of a poor young woman kept prisoner in an apartment by pimps who search to take advantage of her with blackmail affairs. Sorry but I watched it without any subtitle, so it was not so easy for me to get most of the elements I need to bring something correct as a comment. I missed many things unfortunately. But it is not for all audiences. It is bleak, dark and depressing, as many Japanese stuff. I would also say that's more a drama looking like Daniel Duval's LA DEROBADE than a yakuza movie, a crime or even action flick.
