In a certain era, the 300-year-old Shogunate was overthrown by the Meiji Restoration, and the idea of male superiority over women came to an end, and a new era of women ruling over men was ushered in. Women gained power and wealth, and the brothels where women sold their bodies to men fell into disuse, while "brothels" where men sold pleasure to women developed. Among them, the brothel "Yamaguchian," which had respected tradition and protected its form, was the most prosperous in the area, and was called the "den of sluts" by men who feared it.
