Biography
Emperor Sutoku, born on July 7, 1119, in Kyoto, was the 75th emperor of Japan. He reigned during the late Heian period from 1123 to 1142, taking the throne as a child under circumstances that deeply affected his life. His father, Emperor Toba, doubted Sutoku's paternity, suspecting the child was actually fathered by the retired Emperor Shirakawa, Toba's own grandfather. This suspicion strained their relationship and paved the way for future political conflicts.
Sutoku was forced to abdicate in 1142 in favor of his younger brother, who became Emperor Konoe. With his own son passed over for succession, Sutoku felt slighted. When Emperor Konoe died in 1155 without an heir, Sutoku hoped he or his son would be restored to power. However, Emperor Go-Shirakawa was placed on the throne through the maneuvering of the retired Emperor Toba and rival actions by the Fujiwara regent Yorinaga. These political setbacks led Sutoku to team up with Fujiwara no Yorinaga against Go-Shirakawa and the ruling group, leading to the Hogen Rebellion in 1156.
The Hogen Rebellion was a brief but significant conflict that took place in Kyoto. Sutoku's forces were defeated, and he was captured and sent into exile to Sanuki Province on Shikoku. It was the first time in centuries that an emperor had been exiled, a humiliation he deeply felt. His wife, Fujiwara no Kiyoko, as well as Hyōenosuke no Tsubone, stayed away from him during his exile. He was not allowed to return to the capital and reportedly became deeply despondent.
In Sanuki, Sutoku turned to Buddhism and wrote waka poetry. He copied Buddhist sutras with his own blood as a form of devotion and penance, offering them for those killed in the rebellion. When the court rejected these sutras, thinking they were cursed, Sutoku reportedly swore vengeance, biting the tip of his tongue and writing a curse in blood before sealing the sutras in the sea. This act contributed to his reputation as a vengeful spirit after his death.
Emperor Sutoku died on September 14, 1164, in Sanuki, and was enshrined at Tsuzumigaoka Shrine. In the years following his death, a series of disasters hit the imperial court and the capital, which many believed were caused by his angry spirit. He came to be viewed, along with Sugawara no Michizane and Taira no Masakado, as one of Japan's Three Great Onryo, powerful vengeful ghosts thought to bring harm to the living. Shrines were later built to honor him and calm his spirit.
Before Fame
Sutoku was born on July 7, 1119, in Kyoto, into the highest level of Heian court society. His birth was mired in controversy, as his father, Emperor Toba, reportedly bitterly referred to him as the child of his own grandfather, the retired Emperor Shirakawa. Despite this rocky start, Sutoku became emperor at just five years old in 1123, while real political power was held by retired emperors and Fujiwara regents working behind the scenes.
His early life played out in the ceremonial world of the late Heian court, where waka poetry, Buddhist devotion, and aristocratic rituals were daily activities. He received a solid education in classical poetry and court culture, and became quite skilled as a waka poet. However, the political system known as insei, in which retired emperors had the real authority, meant that Sutoku had little actual power during his reign. Growing tensions with his father, Emperor Toba, steadily increased, leading to the resentment that would ultimately drive him to open conflict.
