Goryō

In a broad sense, Goryō (御霊; Japanese: [ɡoɾʲoː]) is an honorific for a spirit, especially one that causes hauntings, and the term is used as a synonym for onryō (怨霊, vengeful Japanese ghosts). In a narrower sense, it refers to a noble or accomplished person who lost a political power struggle or died prematurely from an epidemic or other disease, becoming an onryō that brings pestilence or famine and is later enshrined as a kami in Shinto shrines. For example, the "Sandai Jitsuroku" (a historical Japanese document) mentions that six Shinto shrines were dedicated to the worship of goryō, which were the spirits of those who died from non-natural causes. Later on, two more shrines were added, bringing the total to eight.

Goryō Shinko (御霊信仰, Belief in goryō) refers to the belief that the onryō of people who have died unfortunate deaths cause hauntings and disasters, and the belief that they are enshrined as kami to appease them.
