TRANSLATION: river baby
ALTERNATE NAMES: kawa akaji
HABITAT: rivers, streams, ponds, swamps
APPEARANCE: Kawa akago are cousins of the kappa, and trickster yōkai. They look like small, red-skinned babies.
INTERACTIONS: Kawa akago appear on riverbanks and call out to passersby, perfectly mimicking the sound of crying human babies: “Waah! Waah!” (Japanese: “Ogyaa! Ogyaa!”) When someone wanders down to the river’s edge, the kawa akago retreats further into the underbrush and calls out again. This continues with the yōkai leading its victim further and further into the river. Finally, it sneaks up under the unsuspecting human, pulls his legs out from under him, and sends him tumbling into the river. While this is only meant as a prank, some people drown in this manner. This makes kawa akago a fairly dangerous yōkai.
ORIGIN: Similar yōkai called yama akago (mountain baby) are found in Akita Prefecture (old Dewa Province). They hide in leaf piles in the mountains, and when people step on the leaves, they call out in a loud voice, “Ouch! That hurt!” Then they laugh and vanish into thin air.
TRANSLATION: rainfall priest boy
HABITAT: found throughout Japan; appears during rainy weather
APPEARANCE: Amefuri kozō resemble young boys. They wear children’s kimonos, wooden clogs, and wide-brimmed straw hats or umbrellas on their heads. They are not particularly cute, and have pudgy, upturned noses.
BEHAVIOR: Despite their childish appearance, amefuri kozō are charged with the very important task of causing rainfall. Wherever they go, they cause clouds to form and rain to come down. In ancient China, amefuri kozō were thought to be the servants of the god of rainfall, who is known as Ushi in Japanese.
INTERACTIONS: Amefuri kozō are shy and rarely interact directly with people. However, they enjoy stealing people’s umbrellas and wearing them as hats. They then cause rain showers to fall upon their victims.
ORIGIN: Amefuri kozō became widely known thanks to the printing boom during the Edo period. They were common characters in the cheap, pocket-sized publications sold by street vendors known as kibyōshi, or yellow covers. Kibyōshi were satirical comics, heavy on illustrations, depicting urban life with easy-to-read prose. Amefuri kozō and other priest boy yōkai became popular in these adult-oriented comic books. People enjoyed their grotesque, silly, yet somewhat cute appearance.
LEGENDS: Rain that falls while the sun is out is known in Japan as kitsune no yomeiri—fox weddings. Kitsune (fox yōkai) hold their weddings during sun showers. Before getting married, kitsune will say a prayer to the amefuri kozō for rain on their wedding day.
