Shimoina Districtしもいなぐん

In historical sources, Ame-onna first appears in Toriyama Sekien’s illustrations, though his entry leans on an allegory from Chu, leaving the standalone monster image faint. In oral traditions nationwide two types stand out. One is a female apparition on rainy nights that targets children (such as Shinshu’s “Ame-onba”), with motifs like approaching crying children on night roads and carrying a sack. The other is a numinous being that summons rain in drought, tied to rain-invoking rites and shrine prayers, venerated as a symbol of blessed showers. Rather than contradicting each other, these reflect a folk reading of rain’s dual gifts and perils. From early modern times, a nickname meaning “one who brings rain” also stuck to individuals, but that is a social label, not a yokai image. Sources vary widely by region, and many tales leave names and citations unspecified.
