A yokai depicted by Toriyama Sekien in Konjaku Gazu Zoku Hyakki. His note states, “Jami belongs to the class of chimi,” presenting it as the malevolent vapors and wicked forces that pervade mountains and forests, or as a catch‑all for harmful demonic presences. Not a native Japanese creature, it visualizes an abstract malign entity found in Chinese writings. Its form is not fixed; it is linked to noxious airs and curses, bringing illness and delusion to humans.
Folklore & Legends
In various Chinese miscellanies, the malign airs of wilds and mountains are said to possess people and cause sickness; accounts describe Taoist priests or immortals summoning and subduing them with talismans. The Shenxian Zhuan includes rites to draw out and seal such demons from the sick, later interpreted as referring to jami. In Japan, Sekien’s image popularized the concept, and it came to be treated simply as one of the chimi-moryo, with few localized traditions attached to it.

This version organizes the image of the Jami as an example of Sekien aligning a Chinese-origin demonic concept within Japan’s yokai system. Its original sense is “pernicious enchantment,” classed among chimi, a noxious presence born from the gloom of mountains and wastelands that harms body and mind. Its form is not fixed in classical texts, and images function more as visualizations of an idea. The effects fall between illness and invisible curse—fever, hallucination, frenzy—sometimes triggered by contact with resentment or defilement. Countermeasures include bans, talismans, and wards; traditions speak of drawing a prison on the ground to summon and seal, binding it by asking its name, or transferring it into a vessel. In Japan it rarely became an object of distinct cult, often treated as a generic term alongside more-ryo. In folk terms it is distinguished from miasma, mononoke, and tsukumogami, a high-abstraction yokai appearing where the chill of wild places intersects with human grudge.
