安德天皇
In 1180, Emperor Takakura was forced to abdicate by Kiyomori; Prince Tokihito ascended the throne as Emperor Antoku. Now an empress dowager, Tokuko received the name Kenrei-mon In. In this period, the names of the several gates in the walls surrounding the Imperial grounds refer not only to the wall-openings themselves; these names were also used to refer indirectly to a nearby residence of an empress whose husband had abdicated, or as an indirect way of referring to an empress dowager herself.
