Onryō

The onryō (怨霊, «rancorous spirit») is not defined by how it looks but by why it returns: a specific grievance, almost always suffered in life and almost always beyond repair. While the ordinary dead depart after the funeral rites and join the cult of the ancestors, the onryō remains because something was left unsettled: a betrayal, a false accusation, a love cut short, an unjust death. Rancour (urami) works both as anchor and as fuel. The belief is ancient: already in the Heian period plagues, fires and disasters were blamed on the spirits of the wronged, and collections such as the Konjaku Monogatari-shū (12th century) gather tales of the dead coming back to collect outstanding debts. Ueda Akinari's Ugetsu Monogatari (1776) raised the motif to literature: in his tales the dead return with the punctuality of a contract, because what moves them is not malice, it is the grievance.

The image everyone recognises today (a white burial kimono, immensely long loose black hair, hands drooping before the chest and no legs) is not ancient: it stabilises in the painting of the Edo period, and tradition credits Maruyama Ōkyo, in the 18th century, with the first canonical portrait of a legless ghost. The white kimono is the kyōkatabira in which the dead were shrouded; the loose hair breaks the bound hairstyle that social order demanded of a living woman. From painting it passed to the woodblock print (Hokusai devoted plates of his Hyaku monogatari series to Oiwa and Okiku, and Tsukioka Yoshitoshi composed his «New Forms of Thirty-Six Ghosts») and to kabuki theatre, whose stage machinery of trapdoors, puppets and tearing lanterns turned the onryō into a spectacle. Japanese horror cinema inherited that image whole; what the 20th century added is dated, not backprojected.

Japan condensed the archetype into three tales that tradition groups as the three great ghost stories (Nihon san dai kaidan), and all three protagonists are in this catalogue. Oiwa, from Tsuruya Nanboku's Yotsuya Kaidan (1825), is the wife disfigured by her husband's poison: she returns with half her face ruined to pay the betrayal back. Okiku, from the legend of Banchō Sarayashiki, is the maid falsely accused of losing a precious plate and thrown into a well: she returns to count plates and never reaches ten. Otsuyu, from the Botan Dōrō (a Chinese tale acclimatised into Japanese by Asai Ryōi and later popularised by rakugo and the stage), is the dead lover who visits her beloved every night with a peony lantern. Each embodies one variant of the grievance: conjugal betrayal, the injustice of the powerful, love cut short by death. None of them is a monster: all three are victims first, and that inversion (the powerless victim who in death becomes unstoppable) is the heart of the archetype.

The way out is not always to defeat the onryō; often that is impossible. Tradition here distinguishes the goryō, the spirit of a wronged noble (Sugawara no Michizane, Taira no Masakado, Emperor Sutoku) whom the State appeases with official cult and even with shrines of his own, from the common onryō, who is usually someone powerless in life: a wife, a maid, a girl in love. Its posthumous strength inverts that powerlessness. An onryō is appeased with complete funeral rites, with prayers and memorial services, or by completing what was left half done: in a famous variant of Okiku's legend, someone shouts «ten!» after the ninth plate and the spectre, its account settled, vanishes. Pure exorcism is rare; reparation is the norm. That is why the onryō is, more than a monster, a form of memory: the reminder that an unburied grievance ends up rising back to the surface.
