Kawa-Akago - 川赤子 - [Yokai]

•About this Yokai•

Kawa-Akago (JP: 川赤子) aka the "river baby"

a sneaky child like kappa cousin who's modus operendi is mimicing noises: in particular it sounds exactly like a human baby. it hides under the reeds by the shores, cries & then when someone tries to save what they think is a drowning child, it pulls the good samaritan under, often drowning them instead.

• History and early appearances: Kawa Akago appears in Toriyama sekiens Konjaku zoku Hyakki. (1779) - it might be related to other yokai such as kappa or the similar, yama akago from akita prefecture.
