The Konaki-jiji / Koji (子泣き爺), translated literally as the "Crybaby Old Man" or "Crybaby Geezer," is a prominent example of a Japanese yōkai (supernatural spirit) characterized by a profound and unsettling paradox of form. Its definition establishes a foundational tension: it is a figure that can take the appearance of an old man or a baby, but in either manifestation, it is identified by the sound of a desperate, high-pitched infant cry. This initial contradiction foreshadows the yōkai's deeper connection to the dual social crises of abandoning both the young and the old.

The historical trajectory of the Konaki-jiji reveals a process of folkloric standardization. The term originated in Shikoku, documented within localized family records used to describe an old man who possessed an unusual, child-like cry. The subsequent inclusion of this regional description into a national encyclopedia of yōkai was pivotal, transforming the localized observation into a nationally recognized phenomenon. This process of scholarly codification gave the Koji a stable, standardized identity that proved vital for its later utilization in popular culture. Furthermore, the theme embodied by the Konaki-jiji—a deadly, clinging burden—is not unique to Japan. Folkloric comparisons link the Koji to similar European spirits, specifically citing the Scandinavian Myling (a ghost of an unburied baby), the Slavic Poroniec, and the Germanic Aufhocker. The existence of these cross-cultural parallels suggests that the Konaki-jiji narrative resonates with a universal human anxiety regarding the moral and material weight of neglecting the most vulnerable members of any society.
The geographical origin of the Konaki-jiji firmly roots the legend within the mountainous interior of Shikoku, specifically identifying its cradle in the local folklore of Tokushima Prefecture. The definitive "ghost mountain" complex associated with this yōkai is located in the Oboke-Iya Valley region of Miyoshi City. This area is nestled within the deep, rugged mountains surrounding the sacred peak of Mt. Tsurugi. The environment, defined by extreme geographical peril and profound historical seclusion , is not merely a setting but a crucial, active component in the genesis of the legend. This report posits that the Konaki-jiji acts as a spiritual manifestation of the social and moral burden incurred by life in this remote and treacherous landscape.

The Konaki-jiji is a master of predatory deception. Its standard appearances—an old man or a baby —are carefully chosen to evoke pity and override traveler caution. It is often found crying in remote mountain recesses, locations where the presence of a human infant would be unexpected and cause for alarm. A notable, grotesque variation of the folklore depicts the Koji as a fusion: having the body of a baby but the distinct head of an old man. This combination of the temporal extremes of the human life cycle—infancy and advanced age—is deeply psychologically unsettling, reinforcing the layered thematic analysis that ties the spirit to abandonment practices affecting both the young and the elderly.
The yōkai's hunting strategy relies entirely on exploiting human empathy. By emitting the desperate sound of a crying baby, the spirit triggers the fundamental human desire to offer aid (ninjō). The traveler, often weary and alone on a remote mountain road , is tricked into picking up the seemingly helpless creature.
The encounter culminates in the lethal transformation: immediately upon being lifted, the Koji sheds its deceptive appearance and suddenly becomes a dense, heavy stone or boulder. This transformation is fatal; the spirit "clings on so tightly that it is impossible to release" , ensuring the death of the victim by crushing or suffocation. The magnitude of the attack is quantified in specific folkloric accounts, which cite weight increases up to 50 "kan" and even 100 "kan" (approximately 188 kg to 376 kg). This extraordinary weight guarantees the crushing of the unfortunate person. While the vast majority of encounters result in death, some lore suggests the possibility of survival if the victim reacts quickly enough to drop the creature, leaving the traveler merely "stunned and surprised".
The explicit specification of the crushing weight in "kan", a traditional Japanese unit used for quantifying economic burdens and commercial goods, grounds the supernatural threat in socioeconomic terms. One hundred "kan" represents a massive, life-threatening mass, illustrating that the burden imposed by the yōkai is not merely spiritual but represents the literal, material cost that families during periods of scarcity could not afford to sustain. The encounter acts as a deadly parallel to the historical economic pressures that drove the practices of kin abandonment.
The Konaki-jiji myth finds its definitive geographical home in the Tokushima Prefecture on Shikoku, Japan's smallest main island. The yōkai is described as being "born in the perilous Oboke area" of Yamashiro, which is part of Miyoshi City. This location is not accidental; the region is characterized by extreme isolation. The Iya Valley, which forms part of this complex, is recognized alongside Shirakawa-go and Shiiba Village as one of Japan's "Three Most Mysterious Lands". This profound seclusion is intrinsically linked to the spirit’s narrative of abandonment and danger.
The geography of the Konaki-jiji's birthplace directly informed the mythos. The Oboke and Koboke gorges, carved by the Yoshino River, are marked by exceptionally steep mountainsides and narrow, treacherous paths. The names themselves provide a crucial linguistic clue: Oboke and Koboke translate to "Big Dangerous Steps" and "Small Dangerous Steps," personifying the immense difficulty and danger involved in traversing the region.
The Konaki-jiji is thus seen as a cultural manifestation of the environment itself. The crushing weight that the spirit imposes on the traveler represents the inescapable geographic and economic hardship intrinsic to the region. Historically, this isolation and ruggedness amplified resource scarcity, making the desperate act of abandonment a greater probability. The yōkai haunts the treacherous paths, punishing those traversing the very terrain defined by its danger.
In the contemporary context, Miyoshi City has embraced this folklore as a source of local pride and tourism, a profound cultural reversal. The figure that once symbolized lethal isolation and crushing social guilt has been transformed into marketable cultural capital. Stone statues of the Konaki-jiji are deliberately erected along the Fujikawatani Valley near Oboke, serving as physical place markers that confirm this deep mountain region as the definitive site of the myth. Tourists can visit the Rest Area Oboke's Yokaiyashiki (Yokai mansion), which features the Koji and other local spirits, turning the terror of the "ghost mountain" into a tool for regional revitalization.
The "ghost mountain" linked to the Japanese yōkai Konaki-jiji is the secluded and geographically perilous complex of the Oboke-Iya Valley in Miyoshi City, Tokushima Prefecture. This region, situated beneath the sacred peak of Mt. Tsurugi, is historically defined by extreme isolation and economic hardship, leading to its identification as one of Japan's most mysterious lands.
The Konaki-jiji is far more than a simple monster; it is a profound allegorical articulation of social guilt. By combining the figure of the old man and the infant and transforming into a deadly, crushing weight—quantified in massive units of kan—the yōkai serves as the vengeful manifestation of the community's failed moral obligation to protect its most vulnerable members through periods of scarcity and famine (ubasute and child abandonment). The enduring popularity of the Konaki-jiji, cemented by the work of Shigeru Mizuki, demonstrates modern Japan's continuing fascination with and reappropriation of its darker regional folklore, effectively transforming the literal danger of the "dangerous steps" into a compelling cultural legacy.
