Ittan-Momen is a yokai from Kagoshima Prefecture, described as a strip of cotton cloth about ten meters long (one tan, a traditional unit of fabric length) and roughly nine centimeters wide. At dusk or nighttime, it is said to flutter through the air and wrap itself around a person’s face or neck, suffocating them. Its form is nothing more than a piece of cloth, voiceless and silent in its movements. The name appears in Ōsumi Kimotsuki-gun Dialect Collection (by Denji Nomura, with contributions from Kunio Yanagita), where it was told as a cautionary tale for children. Interpretations vary: some see it as a discarded cloth transformed into a spirit (tsukumogami), while others view it as a manifestation of the wind.
