As a "white apparition," the Yuki-onna is told of as a white figure that suddenly stands in one's path on a blizzard night, leaving no footprints. Before she draws near, the air first turns cold and one's breath freezes white; then, in the glow of the snow, a woman with a long trailing hem floats dimly into view. This sense that "the cold announces her before she comes" is the shared core of encounter-tales across the regions. Her face alone is translucently pale, her eyes glint from within, and she either gives no answer when addressed or asks one's name in a low voice. In many versions the taboo runs thus: answer her question and your life-force is drained; stay silent and you are spared.

The tale of Minokichi and O-Yuki that Lafcadio Hearn set down in Kwaidan^[3] conveys this white-apparition image most vividly. Having frozen the old woodcutter Mosaku to death in a storm-bound hut, the snow woman leaves the young Minokichi with a single command: tell no one what you have seen tonight. Later Minokichi weds a traveling woman named O-Yuki, fathers children, and lives happily — until one snowy night, watching his wife's pale profile as she sews by lamplight, he sees in her the face of the snow woman of long ago and lets the words slip. O-Yuki reveals herself, declares that she spares him only for the love of their children, and vanishes through the smoke-hole as a white mist. A bond sealed by a single forbidden word comes undone: the sorrow of parting, and the otherworldly woman who longs for a human, crystallize here.

In pictorial tradition she is usually painted as a tall woman in white in pale washes, her outline never drawn too firmly, dissolved into a white scarcely distinguishable from the snow. Her feet are blurred into haze and she casts no shadow, lending the air of something not of this world. Less a spirit who sings and dances than a still apparition who stands without sound and vanishes without sound — that is the true nature of the Yuki-onna as a "white apparition."
