The "Woman Missing Her Lower Half" as a Post-War Japanese Horror Motif. While the basic description traces her origins and spread, a deeper analysis repositions Teke Teke within a broader cultural sphere: the motif of the "physically mutilated female ghost" in post-war Japan. The "female ghost lacking a complete body" is a recurring archetype in Japanese horror. From Oiwa (facial disfigurement, Nanboku Tsuruya's "Tokaido Yotsuya Kaidan," 1825) and Kasane (facial and bodily disfigurement, Encho Sanyutei's "Shinkei Kasanegafuchi"), to post-war entities like the Slit-Mouthed Woman (mouth disfigurement, first appeared in Gifu in 1979), Teke Teke (missing lower half), Kashima-san (missing lower half), and Hachishakusama (abnormal height), there is a common thread of "the loss of female physical integrity." Within this lineage, Teke Teke is unique for her connection to the "railway," a piece of post-war Japanese infrastructure.

The Linguistic Choice of the Onomatopoeia "Teke Teke". The name "Teke Teke" mimics the sound of crawling on both arms, and this specific onomatopoeia is the result of several linguistic choices. First, the combination of the plosives 't' and 'k' suggests the hard, striking sound against a wooden floor or concrete. Second, the repetition (teke-teke) creates an eerie sense of a "slow, continuous pursuit." Third, it rolls easily off the tongue, making it easy for children to reenact. Derivative names like "Patapata," "Kotokoto," and "Katakata" have all undergone similar phonological selections, demonstrating a folk-acoustic pattern of "expressing the sound of movement with a two-syllable onomatopoeia."

The Genealogy of Railway Accident Urban Legends. Japan's railways during the post-war period of rapid economic growth were the site of numerous fatal accidents, becoming a hotbed for ghost stories. Alongside Teke Teke, various railway and crossing-related legends have been recorded nationwide since the 1970s, such as "a woman standing behind you when you look back at a crossing," "a figure missing its lower half at the edge of a platform," or "being spoken to by a woman waiting for a train along the tracks." In "The Folklore of Yokai" (Iwanami Shoten, 1985), folklorist Noboru Miyata argued that post-war urban infrastructures (railways, tunnels, housing complexes) function as new spaces for generating ghost stories, replacing traditional locations like bodies of water, crossroads, and mountain passes. Teke Teke is perhaps the most successful entity born of these "infrastructure ghost stories."

Cross-referencing with Kashima-san and the Structure of the "Answer". The method to survive Teke Teke—"answering 'Kashima-san'"—spread widely as a derivative rule. This follows the same pattern as answering "pomade" or "bekko ame" (tortoiseshell candy) to the Slit-Mouthed Woman, actively engaging children's imaginations by embedding a "correct answer" within the story. The countermeasures for Kashima-san herself are diverse, such as "answering 'Kamashi'" or "chanting the full name 'Reiko Kashima'," turning the countermeasures themselves into a trend among children. This can be read as a secularized form of the spells and mantra beliefs that have existed since the Heian period, now taking place within the school environment.

Interpretation of the 2009 Film Adaptation. Director Koji Shiraishi's film "Teke Teke" (2009) adopted the Kakogawa, Hyogo origin theory, depicting the monster as a woman (real name "Reiko Kashima" = Kashima Reiko) whose lower body was severed in a post-war railway suicide. The film reconstructed the oral cross-referencing between Teke Teke and Kashima-san as "two sides of the same person." Bolstered by its connection to the idol culture of the time—starring AKB48's Yuko Oshima—Teke Teke served as a prime example of how post-war children's oral ghost stories were mediated into mainstream Heisei-era cinematic horror.

Reproduction in the Internet Age. Since the 2010s, Teke Teke has been repeatedly reproduced through ghost story reading channels on YouTube, paranormal content on Niconico, and horror shorts on TikTok. In the 2020s, she has been embraced anew by Generation Z as a "scary story told at school during childhood," making her a rare case of an 80s-90s children's oral tradition successfully passing down through generations. Teke Teke is perhaps the clearest example of how the lifeline of a ghost story can endure while adapting its medium from "oral tradition → children's magazines → movies → the internet."
