The Great Spider is a spider that has lived long enough to gain supernatural power, troubling people and monks. It hides in the mountains or in temple rafters, brushes people’s faces late at night, and drains their vitality, causing illness. It may take human form—often as an old woman—and ensnare victims with silk. References appear in records and essays; it may also be called “mountain spider” or “tsuchigumo,” though details and abilities vary by region.
Folklore & Legends
Early Edo anecdotes tell of a Great Spider that turned into an old woman at midnight to attack a man, only to flee after having a leg cut by his sword. A kana-zōshi tale relates a yamabushi lodging at a temple who severed a hairy hand reaching from the ceiling; at dawn, a spider’s corpse measuring about 2 shaku 8 sun was found beside the altar. Records from Shinano describe a Great Spider visible only to the sick, draining their life, and being slain through the efforts of a mother, her child, and neighbors. These stories reflect the folk belief that aged spiders transform.
A tradition-grounded composite of spider apparitions said to gain occult power through great age, lurking in mountain passes, temple rafters, and caves. Appearances range from an ordinary spider grown enormous, to a hairy arm extending from the ceiling, to an old woman in human guise. Avoiding notice, it moves by night, saps vital energy, and binds victims with silk. In slaying tales it often retreats after its limbs are severed by blades, or reveals its true form and is later found as a corpse. Names and lairs vary; reports surface sporadically in local curiosities and essays. Though terms like yamagumo and tsuchigumo sometimes overlap, here it refers broadly to eldritch old spiders.
