Mononoke — Who Is It in Japanese Mythology

What the Word 'Mononoke' Originally Meant

Mononoke is not the name of a specific creature, but a Heian term for an unexplained illness, madness, or misfortune caused by a possessing evil spirit — most often an ikiryō (the spirit of a living person) or an onryō (the spirit of the dead). In court literature of the 10th–11th centuries, including 'The Tale of Genji', doctors and monks literally 'diagnosed' mononoke as the cause of an ailment and performed exorcism rituals to expel the possessing spirit.

• Classical meaning: an invisible curse or possession by an evil spirit.
• Manifestations: unexplained illness, madness, misfortunes without visible cause.
• Connection to the 'Genji' plot: Lady Rokujō's mononoke possesses her rivals.
• Modern shift in meaning: after Miyazaki's film, 'mononoke' is often used colloquially to mean 'forest spirit'.

Why It Is Not Sought in Chronicles of the Gods

Unlike the gods of the pantheon, mononoke is practically absent from the 'Kojiki' and 'Nihon Shoki' — this concept came later, from court prose and medical practice of the Heian period, not from state chronicles about the gods.

物の怪 — 'Strange Thing'

How the Writing 物の怪 Is Analyzed

物の怪 is read もののけ: 物 'thing, creature' plus の 'possessive particle' plus 怪 'strangeness'. Literally — 'strangeness of a thing/creature', indicating that something behaves not as it should due to external interference.

物 — значение: thing, object, to matter — онъёми: ブツ、モツ — кунъёми: もの、もの- — 8 штрих(ов). 物 — 'thing, creature': on the left is the cow 牛, on the right the phonetic. The same character appears in 動物 (animal) and 食べ物 (food).

How Miyazaki's Film Changed the Meaning of the Word

• 'Princess Mononoke' (1997) — Hayao Miyazaki's film used the word for forest and animal spirits, not for the classical curse, and it is this interpretation that became the most famous outside Japan.
• The anime 'Mononoke' (2007) — a medicine seller exorcises various mononoke, closer to the traditional meaning of the term.
• Adaptations of 'The Tale of Genji' regularly show scenes of the exorcism ritual for mononoke at the bedside of the sick.
• Horror games about possession often borrow the classical interpretation of the term rather than the image from Miyazaki's film.
