Amefuri-Kozō (雨降小僧 or 雨降り小僧, lit. Rainfall boy) is a recurring human-like yōkai.
Amefuri-Kozō is a short, child-like yōkai, having a pudgy face and upturned nose. He wears a blue kimono, a pair of getas, and an umbrella over the blue cloth wrapped around his head. He is always carrying around a thin paper lantern.
Amefuri-Kozō appears in episode #21 of the sixth anime adaptation, Flame on! The Solitude of the Takurō-Bi. He appears again in episode #28 along with Takurō-Bi and the other yōkai of GeGeGe Forest to help Kitarō fight off the Western Yōkai. After Backbeard and his army retreats for the time being, Amefuri-Kozō conjures rain to put out the fire that was consuming GeGeGe Forest.
Rain Conjuring: As his name implies, Amefuri-Kozō is able to conjure the rain at his command by using his paper lantern. However within the fifth anime, this ability is uncontrollable.
Amefuri-Kozō is a weather spirit illustrated by Sekien Toriyama in his book "Konjaku Gazu Zoku Hyakki."
