Ittan Momen (Japan)

Ittan momen are sentient sheets of cloth that suffocate people. They belong to a class of yokai called tsukumogami, which are household objects that acquire souls after existing for an extended period.  

An ittan momen strangles its victim to death by wrapping tightly around their neck and face. Sometimes, it may lift the victim into the sky and drop them from great heights.  

Despite being a piece of fabric, an ittan momen is said to bleed when slashed with a sharp object. These yokai are native to Kagoshima Prefecture, where tales about their sightings have been passed down. Some believe that their origins may be traced back to a regional burial custom in which a white cotton flag is raised during funerals as part of the mourning process.
