She is said to be the daughter of an imperial minister of the Fujiwara clan and a royal princess. Different stories disagree on her date of birth: most place it in the 8th century, during Emperor Shōmu's reign, and suggest she was the daughter of Fujiwara no Toyonari; however, a few state she was the daughter of Fujiwara no Toyoshige, a century earlier.[1][2] It is said that the childless couple had appealed to Kannon and been granted a daughter in exchange for the life of one parent.
