Tengu-tsubute is told as a formless anomaly whose cause has been variously ascribed to tengu, foxes, or divine intent. Stones fly from all directions though no thrower is seen, impacts and sounds are real yet no stones are found, no marks remain, and the events repeat at set hours. Cases are recorded widely from Kaga, Kanazawa, and Edo in urban quarters to shrine precincts, and some reports note that crowds of onlookers or official patrols led to its quieting. Morally it serves as a warning against misconduct and as an omen of crop failure or illness, and older records link it with thunder as stones cast by Tenjin. Folklore studies connect it conceptually to stone-throwing rites, mass petitions, and indochi stone fights, understanding it as an expression of a supernatural will.
