How a rejected prayer, a holy scripture written in blood, became a 700-year curse that toppled an empire.

In this episode of our podcast, we explore one of Japan's most powerful and enduring legends: the story of Emperor Sutoku. We begin by examining the political betrayals that led to his defeat in the Hōgen Rebellion and his subsequent exile. The podcast then details his attempt at spiritual reconciliation by painstakingly creating holy sutras written in his own blood, and the court's fateful decision to reject this offering. This rejection is the turning point that transforms a pious emperor into a vengeful spirit, or onryō, who unleashes a curse to bring down the imperial family. This episode discusses how subsequent historical events, including natural disasters and the rise of the samurai class, were seen as the direct fulfillment of his prophecy. We also look into the cultural concepts of karmic retribution (inga) and the appeasement of angry spirits (goryō shinkō), which culminated in Sutoku's eventual deification. Finally, the podcast touches on his modern legacy and why even 20th-century leaders took steps to appease his spirit.
