Yes. It is said that the religion of Kurozome is the largest spread religion in the entire shinobi world, where as every village, and more distinctively, the five great shinobi nations, all possess followers of this religion. Iwagakure, however, prohibited any prayers/rituals that they tried to do, almost sort of like a holocaust. Sayuri, after the black crown attacked Iwagakure, would have taken advantage of that asset, and basically them told, "yo look, if you come with me, you can practice your religion and do whatever you want."

That became the basis and what fundamentally built Usogakure from bottom up, religious tolerance. All of those that couldn't be Kurozomian in iwagakure followed Sayuri into Usogakure. That is what I mean by survivors of Iwa, those kuromizan survivors who survived the holocaust.
