As told in the 14th-century history Taiheiki, Lady Kaoyo’s stunning beauty made her famous throughout the shogun’s court. Enchanted by the mere thought of her, Lord Ko no Moronao decided that he needed to witness her beauty firsthand. With the help of another woman of the court, he secretly watched Lady Kaoyo as she left her bath. Obsessed with what he had seen, he tried to take Lady Kaoyo for himself by accusing her husband Enya Takasada of treason. Takasada and his family were killed as they tried to flee. In this work, Lady Kaoyo steps into the dim light of the crescent moon, unaware of the voyeur beyond the fence. Moronao peeks over his fan, aroused by the private scene.
