Emperor Sutoku was the 75th emperor of Japan, who reigned in the twelfth century before being forced to abdicate and later exiled following the Hōgen Rebellion. After his death in exile, he became venerated as one of Japan's most feared onryō, or vengeful spirits, with various shrines and memorial rites established to pacify his spirit and honor his memory. His story is often cited in discussions of goryō belief, the practice of enshrining wronged historical figures to ease their resentment and protect the living.
