Fujiwara no Tamako
, also known as , was an empress consort of Emperor Toba of Japan, and mother of Emperor Sutoku and Emperor Go-Shirakawa. She was the eldest daughter of . Life 
Tamako's father died when she was seven years old, and she was raised by the retired Emperor Shirakawa and his favorite mistress  (Gion no Nyogo was Taira no Tadamori's wife also Mother of Taira no Kiyomori). Once she grew up, she was almost engaged to the heir of the regent Fujiwara clan, Fujiwara no Tadamichi, but his father Fujiwara no Tadazane incurred Shirakawa's displeasure by declining the offer due to rumors about Tamako's behavior. In early 1118, with Shirakawa as her godfather, Tamako entered the court of her cousin Emperor Toba. Just a month later, she was invested as Empress Consort (chūgū). In mid-1119 she bore Toba's first child, Prince Akihito. In early 1123, Shirakawa had the five-year-old Prince Akihito ascend to the throne as Emperor Sutoku, and in 1124 Tamako was bestowed the title Taikenmon-in. Around this time Tamako also bore Princess Kishi, Prince Michihito, and Prince Kimihito, but these two princes were born handicapped. She bore Princess Muneko in 1126, and Prince Masahito less than a year later, in 1127. In 1129 she had her final child, Prince Motohito. Tamako bore Toba a total of seven children, and also accompanied him on a trip to the Kumano shrines, but this was all during the lifetime of Shirakawa. When the long-governing retired emperor died in 1129, her life took a turn for the worse. The retired Emperor Toba inherited Shirakawa's reign, commanding the courtiers and isolating the young Emperor Sutoku. He reinstated the kampaku Shirakawa had dismissed, Fujiwara no Tadazane, and married Tadazane's daughter Fujiwara no Yasuko to the young emperor, investing her as kōgō. Furthermore, he transferred his affections from Tamako to another wife, Fujiwara no Nariko. In 1139, Toba appointed his three-month-old son with Nariko, Prince Narihito, as crown prince, and in 1141 pressed Sutoku to resign, letting Narihito take the throne as Emperor Konoe. While this was going on and Nariko was invested as Toba's kōgō, a series of incidents occurred in which someone appeared to be trying to curse Nariko, and a rumor spread that it was Tamako pulling the strings. The Kojidan further states that an additional rumor spread that Sutoku was actually Shirakawa's son, though this rumor is not recorded elsewhere. In 1142, with her power evaporated, Tamako cut her hair and became a nun at , which she had had built herself. Three years later, on September 10, 1145, Tamako died at the estate of her eldest brother . According to the diary entry of Fujiwara no Yorinaga for that day, Toba came running to care for her, and on her deathbed wailed loudly while ringing a metal bell used in the reciting of sutras. In 1155, ten years after her death, Emperor Konoe died at the age of 17, and Tamako's son Prince Masahito was unexpectedly enthroned as Emperor Go-Shirakawa. The court split between supporters of Go-Shirakawa and supporters of Sutoku, culminating in the Hōgen Rebellion. Issue
