The Perfected Form of Honji Suijaku. Kumano Gongen is the most elaborately systematized example of "Honji Suijaku," the Japanese philosophy of Shinto-Buddhist syncretism. Each of the main deities of the Kumano Sanzan was assigned a Buddhist "original ground" (Honji Butsu). For instance, Ketsumimiko-no-Okami of Hongu was identified as Amida Nyorai; Kumano Hayatama-no-Okami of Hayatama Taisha as Yakushi Nyorai; and Kumano Fusumi-no-Okami of Nachi Taisha as Senju Kannon (Thousand-Armed Avalokitesvara). Consequently, a pilgrimage to Kumano functioned as a complete salvation system spanning the past, present, and future: erasing the sins of past lives (Yakushi), gaining benefits in this world (Senju Kannon), and securing a promise of rebirth in the Pure Land in the next life (Amida). Institutionalization and Networks of Shugendo. Kumano is one of the birthplaces of Shugendo, and rather than just a place of prayer, it was a rigorous training ground. From the medieval period onward, Shugendo developed into massive religious organizations such as the Honzan-ha (Tendai sect lineage) and Tozan-ha (Shingon sect lineage), building a nationwide network backed by the religious authority of Kumano. The establishment of "Kumano Shrines" (Junisho Gongen) in various regions was the result of propagation activities through this network of ascetics. The fact that thousands of these shrines still exist nationwide today demonstrates the deep penetration of Kumano Gongen into local communities. The Religious Nature of the "Path" Itself. When discussing the Kumano Gongen faith, the existence of the "Kumano Kodo" (Kumano Ancient Trail) cannot be overlooked. The journey to Kumano was extremely arduous, dotted with numerous small shrines called "Tsukumo Oji." Pilgrims were not merely aiming for a destination; the act of walking the treacherous mountain paths and enduring hardships was itself considered ascetic training to extinguish sins (Dochu Shugyo). Even from the perspective of modern public history, the Kumano Kodo retains its value not just as historical heritage, but as a "space to practice faith" where one purifies the mind using one's own body.

The Theology of "Strict yet Gentle" Duality. The greatest iconographic and doctrinal feature of Fudo Myo-o is the intense contrast between his terrifying appearance and the profound compassion he harbors within. A Wisdom King (Myo-o) is a Buddha who deliberately transforms into a fearsome figure to persuade and instruct; Fudo Myo-o is thus another face of Dainichi Nyorai, the universe's ultimate truth. His wrath is not born of hatred toward evil, but rather an expression of the "extreme limit of compassion" to save wandering souls at any cost. This duality is the primary reason he gathered such broad worship across all classes, from strictly disciplinarian monks to anonymous commoners praying for daily peace. A Hybrid of Worldly Benefits and Memorial Services. Originally, in Esoteric doctrine, Fudo Myo-o was a spiritual pillar meant to lead practitioners to enlightenment. However, as he fused with Japanese indigenous beliefs, he assumed extremely pragmatic roles. From dispelling diseases to preventing fires, and even ensuring modern traffic safety, he acts as a "breakwater" against every threat in daily life. Simultaneously, in the Thirteen Buddhas belief system, he is deeply involved in memorial services for the dead, acting as the guiding deity for the first seventh-day mourning period. Thus, he transformed into an omnipotent guardian deity relied upon throughout the entire process from life to death. Fudo Myo-o and His Retainers. Fudo Myo-o is often depicted in a triad accompanied by Kongara Doji and Seitaka Doji, or surrounded by numerous retainers such as the Eight Great Youths (Hachidai Doji) or the Thirty-Six Youths. This illustrates how Fudo Myo-o's immense power was subdivided to build a system capable of meticulously addressing the diverse wishes of all people. The visual contrast of placing innocent, childlike attendants beside a terrifying central deity is also one of the unique aesthetic and religious expressions achieved by Japanese Buddhist art.

This edition is not about a single seat on a particular sacred mountain, but a general treatise that thoroughly unravels "what a tengu is" from the history of its iconography and types. The individual traditions of each seat are left to the page of each great tengu. The form of the tengu is not uniform. The first type is the long-nosed tengu—ruddy face and high nose, clad in the ascetic's headcloth (tokin) and the suzukake robe, a feather fan in hand and one-toothed high clogs on the feet. The second is the crow tengu, with a crow's beak and wings, grasping a sword or a vajra staff. The third are the lesser tengu called leaf tengu and wood-chip tengu, held to be weak and numerous kin. Rather than a fixed classification, these reflect the breadth of the tengu image across eras and regions. The iconography shifted over time. The Heian-period tengu was first conceived as a bird like a black kite, and the image of the crow tengu retains that vestige. The long nose grows prominent only from the late Kamakura period; the Zegaibō Emaki depicts a scene in which a tengu that had disguised itself as a human has its nose lengthen as it returns to bird form. As for the origin of the long nose, there are theories that derive it from the high-nosed Jidō mask of gigaku and link the crow tengu to the Karura (Garuda) mask, and a view that sees the long nose as an iconographic vestige of a bird's beak—but none can be called settled doctrine. It was overlaid with the god Sarutahiko, described in the Nihon Shoki as having a nose seven hand-spans long, and the custom arose of using a tengu mask for the role of Sarutahiko in festivals. The tengu's dual nature is rooted in the Buddhist notion of the way of the tengu. Because it studies the Buddhist path it does not fall into hell, and because it handles heterodox arts it cannot reach paradise either—an intermediate state, and the one who falls there was held to be the arrogant monk. The Tengu Zōshi depicts this notion as satire of the monks of the seven great temples, yet Chigiri Kōsai too warns that the simplification "only arrogant monks become tengu" goes too far. Demon though it is, once subdued it turns to guardianship, and it was held that if a Shugendō practitioner recites the Tengu Sutra he may summon the tengu of the various provinces to grant his wishes—this amplitude between guardian and demon is the very core of the tengu. The certain medieval source for the grouping called the "Eight Great Tengu" lies in the libretto of the Muromachi-period Noh play Kurama Tengu. The passage in which the great tengu calls up the tengu of the provinces he commands in geographical order—"In Tsukushi, Buzenbō of Hiko-san; in the four provinces of Shikoku, Sagamibō of Shiramine; Hōkibō of Ōyama; Saburō of Iizuna… the host of Zenki of Ōmine, Takama of Katsuragi"—shows that the Eight Great Tengu were rooted in medieval belief and performing arts, not an Edo invention. Still, the composition wavers by source, with a variant that adds Hōkibō of Ishizuchi-san; it is no fixed roster.

A portrayal of the Ippon-datara based on records from Kii and Kumano through Nara. It is said to be one-eyed and one-legged, but firsthand sightings are rare; in many regions a single large track left after snowfall is taken as proof of its presence. Its most notable trait is appearing on December 20, the “Hate-no-Hatsuka,” a day overlapping taboos of mountain deities and roads, effectively discouraging entry into the mountains. In its link to smithing, folklore explains the one-leg one-eye form as derived from the tatara blower treading the bellows with one foot and watching the furnace with one eye. In the Obagatōge lineage it is equated with the oni-god Inosasao, once a terror of the peak but sealed by a monk and released only once a year. In Kumano and Itsukushima it is said “only footprints appear, not the body,” feared yet seldom directly harmful. While stories of one-legged snow spirits (such as Yuki-nyūdō and Yukibō) have blended with it, this entry centers on the Kumano–Nara stream, emphasizing three points: the taboo day, the single track, and the blacksmith-origin theory.

An Aobōzu type based on images in Edo-period picture scrolls and regional field collections. Depicted as a monk with a bluish hue or as a one-eyed priest, it may be told as an animal in disguise, a manifestation of a mountain deity, or an uncanny being of uncertain nature. It serves to warn children against wandering, anchors tales of hauntings in fields, mountains, and vacant houses, and conveys oral taboos. No fixed proper name or origin is agreed upon, and its conditions of appearance and behavior vary by region. Because Sekien’s print lacks commentary, notes from other sources list it alongside the “One-Eyed Monk” or as an allegory for an unseasoned priest, but neither view is definitive. In premodern oral accounts, concrete images coexist under multiple labels such as “Blue Priest,” “Great Monk,” and “Little Monk.”

An iconographic reading of the Dōjōji bell as depicted in Toriyama Sekien’s Konjaku Hyakki Shūi. While a note alludes to a variant in which the woman, transformed into a serpent, coils around the bell hiding Anchin and heats it until it melts into scalding liquid, hearsay also holds that the bell itself survived in historical record. Its “yokai nature” here is less an ensouled object than a visualization of folk belief in obsession possessing a vessel and causing anomalies. It represents Edo-period reception where Noh, sekkyō, and engi traditions intermingle.

A form rooted in the topographic legends of Kitayama Village. A fox is said to possess a person and display uncanny lightness, leaping across sheer cliffs. Variant tales pit it against serpents or yamabushi ascetics, so rivals and techniques differ by account. Anchored to cliff-line marks cited as physical proof, it serves to evoke the village boundary’s numinous authority and taboos. Ritual details and personal names are not preserved, and narratives remain general in outline.

A classic image of gaki possession said to occur on mountain passes and in the hills. It is understood to stem from the spirits of those starved to death in battles or as wayfarers, so travelers carried a little food and offered it to the pass before crossing to avert harm. Onset is sudden, marked by fierce hunger, weakness in the limbs, and feet that refuse to move, often leaving one unable to rise in shade or where wind passes through. The remedy is simple: even a single grain of rice, a pinch from a salty rice ball, or a scrap of dried fish in the mouth is said to loosen the grip. As prevention, people scattered a bite of their lunch to the mountain deity or the spirits of the unburied dead, or made offerings at roadside Jizo. One should avoid heavy meals at once, easing the stomach with rice porridge or zosui. Though names vary—Iso-gaki on the coast, Hidarugami in basins and farm villages, Jikitori in Shikoku—the symptoms and remedies are nearly identical and closely tied to local practices of memorial and roadside offerings for the dead.

Okuri-suzume has been framed as a harbinger and ill omen warning of dangers on mountain roads. Its calls precede, and are said to lead into, appearances of wolves or the escorting wolf, forming a narrative that encourages careful footing and avoiding delays in the wilds. The name “kuzusuzume” aligned with the real bird Black-faced Bunting (Aoji) is recorded, though its supposed nocturnality is debated. Sightings of its form are scarce, leaving its appearance unsettled, and in parts of Nara it is conflated with the night sparrow. Stories place it around Myohosan in Wakayama, and it is said to draw near lantern light. More than a threat itself, the lore centers on its “foreboding call,” giving it a strong character as a sound-based apparition.

Academic Correction (Most Important Note for this Species): The monsters included in the "Mei" volume of Toriyama Sekien's *Konjaku Gazu Zoku Hyakki* (1779) are Nue, Itsumade, Jami, Moryo, Mujina, Nobusuma, Nozuchi, Tsuchigumo, Hihi, Dodomeki, Buruburu, Gaikotsu, Tenjo-sagari, Ohaguro-bettari, Okubi, Dodomeki, Kanedama, and Amanozako (18 entities in total), and Tsurube-otoshi is not included. What Sekien drew was the related yokai Tsurubebi, which was included in *Gazu Hyakki Yagyo* (1776) — the predecessor to Zoku Hyakki. The original text for Tsurubebi is Yamaoka Genrin's *Kokon Hyaku Monogatari Hyoban* (published in 1686; the "Tsurube-oroshi of Nishinooka" tale in Nishiyama, Kyoto), which theorized the strange phenomenon of a large tree's spirit turning into a fireball and descending from the tree on rainy nights using the Five Elements theory (Wood generates Fire). In other words, the "Yokai Tsurube-otoshi (a severed head or demon mask falling from a tree)" and "Sekien's Tsurubebi (a mysterious fire dropping from a large tree)" are separate lineages that diverged after the Showa era, and Sekien did not directly depict the former. No primary visual sources with the name "Tsurube-otoshi" from the Edo period exist, and it mainly appears as local folklore in Taisho period topographical records and folklore collections. This is a critical correction that must be specified to maintain the academic quality of yokai.jp, and the widespread "1779 Sekien iconification theory" should be explicitly denied. The primary records of Tsurube-otoshi are Taisho period local materials and folklore collections. The Kyoto regional study *Kuchidanba Kohishu* (a Taisho era collection of folklore from Minamikuwada and Funai Districts) serves as the core historical document, recording it as a local legend of mountain roads, passes, and old trees in the Chubu and Kinki regions. The fact that the primary source is not Edo period iconography but local folklore oral collection is a unique characteristic of this yokai, making it an exceptional case that does not fit the generalization that "yokai originate from Edo period iconification." The local folklore of Tsurube-otoshi is concentrated in the Chubu and Kinki regions: 1. Kyoto Prefecture — Hoki, Sogabe Village, Minamikuwada District (present-day Sogabe-cho, Kameoka City; drops from a kaya tree, laughs "Finished your night work? Shall I drop the bucket? Squeak, squeak" and rises again), Tera, Sogabe Village (a severed head descends from an old pine, devours people, and disappears for 2-3 days when full), Tomimoto Village, Funai District (present-day Yagi-cho, Nantan City; a pine tree covered in ivy), Tsuchida, Ooi Village (present-day Ooi-cho, Kameoka City; eats people) — documented in the Taisho period regional study *Kuchidanba Kohishu*. 2. Kuze Village, Ibi District, Gifu Prefecture (present-day Ibigawa-cho) — drops a bucket from a large tree that is dim even during the day. 3. Hikone City, Shiga Prefecture — drops a bucket from tree branches aiming at passersby. 4. Kuroe, Kainan City, Wakayama Prefecture — similar lore. 5. Tamba-Sasayama City, Hyogo Prefecture. 6. Mikawa mountainous region, Aichi Prefecture (folklore in Toyone Village, etc.). It has a geographic characteristic of concentrating around ancient trees (pine, kaya, cedar, zelkova) along mountain roads, passes, and shrine grounds in the Chubu and Kinki areas. Its behavior is bifurcated by region: The Kyoto lineage is predatory (eating people and staying full for 2-3 days), making it a lethal yokai; the Gifu-Shiga lineage is intimidating (only dropping a bucket to scare people), causing little real harm. The Kyoto lineage features a specific predatory pattern of "not appearing for 2-3 days when satiated," and was feared as a murderous monster rather than a mere scarer. On the other hand, the Gifu-Shiga lineage, as its name suggests, simply drops a "tsurube (well bucket)" from a tree to startle people, a relatively harmless yokai positioned between a "supernatural threat" and a "laughing matter." Despite sharing the name "Tsurube-otoshi," the entity itself varies significantly depending on the region, providing an excellent example of the regional diversity of local legends. The modern visual of a "red-faced, bearded, disheveled old man's head" depends heavily on Shigeru Mizuki's artwork and is not the original standard form in local folklore. The original form varies widely by region, splitting into three lineages: 1. A solitary severed head (Tera, Sogabe Village, Kyoto), 2. A formless monster that drops a well bucket itself (Gifu and Hikone, Shiga), and 3. A spirit type accompanied by laughter and speech (Hoki, Sogabe Village, Kyoto). The image of the "red severed head" was popularized through Shigeru Mizuki's manga and anime such as *GeGeGe no Kitaro* and *Akuma-kun*, becoming fixed as the modern general image, but from a folkloric perspective, the standard form changed pre- and post-Mizuki. This is also a perfect illustration of the decisive impact "Mizuki Yokai Culture" had on Japanese people's perception of yokai. The idiom "autumn days drop like a tsurube" (a metaphor comparing the rapid darkening of the autumn sunset to the motion of a well bucket and rope plunging down at once) has no direct lineage connection to the yokai Tsurube-otoshi. They share the same metaphorical source of "a well bucket = something that falls rapidly," but the idiom was established independently as a meteorological expression. However, the fact that the concept behind the yokai's naming (the three elements of falling speed, darkness, and surprise) stands on the same metaphorical foundation as the idiom is noteworthy in cultural history — demonstrating the richness of Japanese metaphorical culture, where an everyday tool like a "well bucket" evolved into both a meteorological phrase and a yokai name. Distinctions from similar yokai: 1. Tsurubebi (the mysterious fire dropping from a tree in Sekien's *Gazu Hyakki Yagyo*, which, as mentioned, is the Edo period origin lineage that diverged from Tsurube-otoshi in modern times), 2. Kodama (tree spirits in general; Tsurube-otoshi is an "individual monster dwelling in a specific ancient tree," a variant of the kodama lineage), 3. Kosoma (an acoustic supernatural phenomenon making axe and falling tree sounds in the mountains, different in nature from Tsurube-otoshi which primarily relies on visual dropping attacks), 4. Severed head lineages (Otoshikubi, Kubikireuma, etc.; they share the "head" aspect, but the Kyoto lineage's severed head in Tsurube-otoshi is an independent yokai entity, not a monster of decapitation). Toriyama Sekien's four-part yokai series consists of *Gazu Hyakki Yagyo* (1776) -> *Konjaku Gazu Zoku Hyakki* (1779) -> *Konjaku Hyakki Shui* (1781) -> *Hyakki Tsurezure Bukuro* (1784), and all images are publicly available on the National Diet Library's NDL Image Bank. Tsurubebi is included in the "In" volume of *Gazu Hyakki Yagyo*. When listing Tsurube-otoshi on yokai.jp, it should be clearly stated that typeOfSource = "Local folklore (Chubu/Kinki)" and firstAttestedSource = Taisho period *Kuchidanba Kohishu*, while explicitly denying the widespread misinformation of the "Edo period Sekien iconification theory." In modern yokai culture, it was popularized by Shigeru Mizuki's *Yokai Zukan* and the bronze statue on *Mizuki Shigeru Road* (Sakaiminato City, Tottori Prefecture), and appears as a Kyoto yokai in *GeGeGe no Kitaro* (3rd season VA: Masato Hirano, 5th season: Hisao Egawa) and *Nura: Rise of the Yokai Clan*. As an excellent example of a grassroots yokai originating from local oral tradition being popularized by Shigeru Mizuki's artwork, Tsurube-otoshi is an important case study showing the modernization mechanism of Japanese yokai culture — a fascinating yokai situated at the intersection of folklore studies, art history, and media theory, demonstrating a modern yokai circulation route from unillustrated Edo period local folklore to Taisho period oral collection, Mizuki's popularization, and modern anime and games.

Based on types recorded around Kumano and Mount Kuanashi, this yokai takes the form of a young woman, asks for a light from a lantern, then steals it and slips into the dark to drain the victim’s flesh or vital essence. In encounter tales, brandishing strong flame from a matchcord or fire striker drives it off, and bullets engraved with Buddhist names expose its true form as a skeletal fiend—mountain taboos and carry-on wisdom are emphasized. Although later images show it slipping indoors to steal vitality while nestled close, this version centers on wilderness meetings and warnings for night travel, noting that lanterns, live embers, and recitation of Buddhist names function like protective charms. It avoids conflation with foreign lore and follows Kii oral traditions and records.

The Night Sparrow is a nocturnal attendant yokai widely told of in the mountains of western Japan, marked by revealing itself through its call. In Tosa it is said to look like a small bird, in Kitagawa and Iyo like a moth or butterfly, and its appearance is not fixed. When someone walks alone, it alternates between the rear and the front, chirping close to the ear and throwing off the walker’s rhythm. In Toyama Village a banishing chant is preserved, and people are warned that rashly trying to catch it brings night blindness. In Wakayama, by contrast, it is taken as a sign that wolves are near and as a protective omen against mountain evils. Related tales include the “okuri-suzume” of Nara and Kii and the “tamutori-suzume” of Kochi and Ehime. In Tsunoyama and Johen they are treated as the same, and avoidance methods include gripping one’s sleeve, setting three twigs upright, or reciting specific mantras. Its folkloric traits are its ambiguous visual form, interference through sound, and regional differences in whether it is seen as ill or auspicious.
