TRANSLATION: oil baby
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.
叢原火 or 宗源火
TRANSLATION: Sōgen’s fire
HABITAT: spotted at Mibu-dera in Kyoto
APPEARANCE: Sōgenbi is a type of hi no tama, or fireball yokai. It appears as the anguished head of an old monk, covered in flame, and flying about the sky.
LEGENDS: Long ago, at the temple of Mibu-dera in southern Kyoto there lived a monk named Sōgen. Sōgen was a wicked monk, for he would steal money out of the temple’s saisen bako, a large wooden box which holds offerings. He also made off with precious oil, which was to be used as an offering for the gods, and sold it in secret, keeping the money for himself. This went on for many years, until eventually Sōgen grew old and died. Because of his wickedness, he was reborn in hell to pay for his sins. Shortly after his death, it was said that the flaming head of old Sōgen could be seen floating about in the vicinity of Mibu-dera.
