HABITAT: human-inhabited areas
DIET: lamp oil

APPEARANCE: Abura akago are yōkai from Ōmi Province. They are a type of hi no tama, or fireball, but can also take on the shape of a baby.

BEHAVIOR: Abura akago first appear as mysterious orbs of fire which float aimlessly through the night sky. They drift from house to house and—upon entering one—transform into small babies. In this baby form, they lick the oil from oil lamps and paper lanterns, known as andon. They then turn back into orbs and fly away.

ORIGIN: Like many other oil-related yōkai, abura akago are said to originate from oil thieves. While the particular circumstances of these oil thieves are lost to time, they mirror so many other yōkai that we can infer that these thieves died and—instead of passing on to the next life—turned into yōkai as a penalty for their sins.
