The Owariya, located in Yoshiwara, was the ageya where Lady Wisteria worked as a tayu in The Pillow Book of Lady Wisteria. It was owned by a man named Eigoro. Each night, if a client wished company of a courtesan from a particular brothel, a message would be sent to the brothel and then the tayu would come to the client at the ageya. Those who came to the Owariya were mostly high ranking officials in the government. Lord Matsudaira Mitsuyoshi was murdered there by Lady Wisteria.
