Emperor Sutoku, Taira no Masakado, and Sugawara no Michizane are called the Three Great Onryō of Japan (日本三大怨霊) because they are considered to be the most powerful and revered in Japanese history. After they died with resentment and anger, there was a series of deaths of political opponents, natural disasters, and wars, and the rulers enshrined them as and deified them in Shinto shrines to appease their resentment and anger that had turned into.

are used as subjects in various traditional Japanese performing arts such as Noh, Kabuki, and Rakugo; for example, is a Noh mask representing a female.

The Japanese people's reverence for has been passed down to the present day. The head mound of Taira no Masakado (将門塚), located between skyscrapers near Tokyo Station, was to be moved several times as part of urban redevelopment projects, but each move resulted in the death of a construction worker and a series of accidents. Although the buildings surrounding the Taira no Masakado mound have been rebuilt many times, the mound has remained intact between the high-rise buildings.

Origin
While the origin of is unclear, belief in their existence can be traced back to the 8th century and was based on the idea that powerful and enraged souls of the dead could influence, harm, and kill the living. The earliest cult that developed was around Prince Nagaya who died in 729; and the first record of possession by the  spirit affecting health is found in the chronicle  (797), which states that "Fujiwara Hirotsugu (藤原広嗣)'s soul harmed Genbō to death" (Hirotsugu having died in a failed insurrection, named the "Fujiwara no Hirotsugu Rebellion", after failing to remove his rival, the priest Genbō, from power).

Vengeance
According to the belief of Ikiryō, a person's soul or spirit exists naturally when it is stable or in balance. When too much hatred or resentment brews, it can become separated from the body, resulting in the spirit becoming an. This can allegedly also occur in individuals who died an untimely death.

Traditionally in Japan, driven by vengeance were thought capable of causing not only their enemy's death, as in the case of Hirotsugu's vengeful spirit held responsible for killing the priest Genbō, but causing natural disasters such as earthquakes, fires, storms, drought, famine and pestilence, as in the case of Prince Sawara's spirit embittered against his brother, the Emperor Kanmu. In common parlance, such vengeance exacted by supernatural beings or forces is termed tatari (祟り).

The Emperor Kanmu had accused his brother Sawara, possibly falsely, of plotting to remove him from the throne. Sawara was then exiled, and died by fasting. According to a number of scholars, the reason that the Emperor moved the capital to Nagaoka-kyō thence to Kyoto was an attempt to avoid the wrath of his brother's spirit, according to a number of scholars. This not succeeding entirely, the emperor tried to lift the curse by appeasing his brother's ghost, by performing Buddhist rites to pay respect, and granting Prince Sawara the posthumous title of emperor.

A well-known example of appeasement of the spirit is the case of Sugawara no Michizane, who had been politically disgraced and died in exile. It was believed to cause the death of his calumniators in quick succession, as well as catastrophes (especially lightning damage), and the court tried to appease the wrathful spirit by restoring Michizane's old rank and position. Michizane became deified in the cult of the Tenjin, with Tenman-gū shrines erected around him.
