Her father was Shigehide NIWATA, Konoe no chujo (middle captain of the palace guards), Jushiijo (Junior Fourth Rank, Upper Grade), and her mother was not known.
Hideko was first called "Katsura no kata." After being appointed to Naishi no suke later, she was called Gen no Naishinosuke, Gen no Otenji, and Koichijo no Tsubone. Onna Ichinomiya was born on November 8, 1650. She was later named Takako. Emperor Gokomyo passed away in four years. Probably because of the short reign of the emperor, few records of Hideko is left. Imperial princess Takako received a title of Princess by Imperial order in 1683, but Hideko passed away on May 4, 1685, two years after that. Her posthumous name was Eiunin (栄雲院).
