Emperor Hanzei also known as Emperor Hansho, was the 18th Emperor of Japan, according to the traditional order of succession. Both the Kojiki, and the Nihon Shoki recorded events that took place during Hanzei's alleged lifetime. No firm dates can be assigned to this Emperor's life or reign, but he is conventionally considered to have reigned from 406 CE to 410 CE. His family included an "Imperial Lady", and "Concubine" which bore him 4 children. Historians have stated that while nothing remarkable took place during Hanzei's brief reign, he did have ranked concubines which is an introduced Chinese custom.
