Translation: pillow flipper
Alternate names: makura kozō
Appearance: Makuragaeshi are a kind of zashiki-warashi: a child ghost which haunts specific rooms of a house. They are found all over Japan, though details about them vary from region to region. They take the form of a small child dressed as a Niō, a monk, or a samurai, and appear in bedrooms late at night.
Behavior: Makuragaeshi gets it is named for its primary activity: flipping pillows. People who sleep in a room haunted by a makuragaeshi often wake up to find that their pillow has been flipped and is now at their feet. Makuragaeshi are also known for other minor pranks, such as running through ashes and leaving dirty footprints around the rooms they haunt.
While most stories about makuragaeshi present them as harmless pranksters, there are a few stories that describe scarier powers. Some don’t flip the pillow, but lift up and flip people instead. Others pick up entire tatami mats that people are sleeping on and bounce them around. Still others are said to sit on their victim’s chest while he or she sleeps, pressing down hard and squeezing the wind out of the lung. They occasionally cause kanashibari, or sleep paralysis. The most extreme stories say that anyone who sees a makuragaeshi loses consciousness, after which the makuragaeshi steals their soul, leaving them dead.
Origin: There are as many theories as to where makuragaeshi come from as there are variants of zashiki-warashi. Most often they linked to the ghosts of people — particularly children — who died in the room they come to haunt. As makuragaeshi are generally lower in rank than zashiki-warashi, they are often the result of ghosts which died tragically, such as murder victims. However, some makuragaeshi have also been attributed to shape-shifting, prank-loving yokai such as tanuki or saru. Others still have attributed this spirit to the actions of monster cats such as kasha.
