The pictorial sources that record furaribi do not supply an explicit prose origin. An interpretive theory noted in scholarship and the source summary proposes that some furaribi represent incarnations of fire formed from deceased persons who were not given memorial rites and thus wandered as unsettled spirits, gradually taking on the fiery forms depicted in the scrolls. Separately, a Toyama (Isobe, Jinzū River basin) local legend links the nightly appearance of ghost-lights—called buraribi or Sayuri-bi—to the aftermath of an execution and a deathbed curse, producing a locally situated haunting tied to a named individual (Sayuri). The memorial-neglect origin is presented in the sources as theory rather than an established, uniform origin story.
In classical yōkai picture-scrolls (Hyakkai Zukan, Bakemonozukushi) furaribi are depicted as birds enveloped in flame with a dog-like face; Sekien Toriyama's Gazu Hyakki Yagyō includes an example rendered as a bird wrapped in fire whose facial rendering an observer has compared to Garuda (this comparison is attributed to the source depiction). The Toyama local tale describes atmospheric ghost-lights without detailing a bird-form and reports that, in that story, calling the light by the name 'Sayuri' causes the apparition of a severed woman's head with disheveled hair—a specific local manifestation distinct from the pictorial bird-imagery.
The pictorial tradition presents furaribi as visible fiery apparitions—bird-formed flames that manifest in the human-visible world. The scholarly interpretation tying some forms to deceased persons not given memorials suggests a behavioral role as lingering, restless manifestations of the unmemorialized dead, though this is explicitly framed as theory in the sources. In the Toyama tale, the related nightly ghost-lights respond to vocal invocation: calling 'Sayuri, Sayuri' summons the apparition of a severed woman's head (the local Sayuri), an ability reported only for that specific regional story rather than for all pictorial furaribi.
Abumi-guchi
A Japanese yōkai classed as a tsukumogami: an animated stirrup (abumi) depicted in Sekien Toriyama's Gazu Hyakki Tsurezure Bukuro. Traditional accounts say it is formed from a stirrup that belonged to a soldier who fell in battle and that it waits where the stirrup lies for its dead owner to return.
Abura-sumashi
A yōkai spirit from the Amakusa region of Kumamoto Prefecture, Japan, said to inhabit mountain passes. Traditionally explained as the ghost of a person who stole oil, it appears to surprise travelers and is represented in modern media with a straw-coat body and a potato- or stone-like head.
Akaname
Akaname is a Japanese yōkai associated with baths, bathtubs, toilets, and other places where scum and filth accumulate. Traditionally depicted as a child-like creature that licks grime, it functions in folklore as a cautionary figure tied to cleanliness; a few narrative variants cast it as dangerously predatory.
Akateko
Akateko (赤手児, lit. 'red child's hand') is a yōkai from Japanese folklore commonly told as a small, red, disembodied child's hand that appears from trees—especially the Japanese honey locust—and startles travelers; in some regional variants it is accompanied by a specter of a young woman or manifests as paired foot- or leg-like apparitions. Accounts vary between mostly harmless trickster apparition and a violent variant that attacks humans.
Akubōzu
Akubōzu (灰坊主, Akubōzu) is a household yōkai from parts of Akita and Iwate Prefectures in northern Japan said to live in the ashes of the hearth. Sources say they appear when people (notably children) play with or dig in hearth/furnace ash; the figure is cited as part of a broader Tōhoku motif warning against disturbing ash.
Akuma
Akuma (悪魔／あくま) in Japanese sources is an evil spirit, devil, or demon associated with misfortune and mental disturbance. The term appears in Buddhist texts and Heian-period literature and was later used to translate the Christian figure of Satan, as well as the Buddhist Mara.
Akurojin-no-hi
Akurojin-no-hi (悪路神の火, "fire of the god of the bad road") is a flamelike ghost from the folklore of Mie Prefecture, Japan. It is reported to appear on rainy nights; those who encounter it and do not run away are said to become gravely ill. The phenomenon is sparsely documented and is usually compared to will-o'-the-wisp type ghost-lights.
Amabie
Amabie is a mid-19th-century Japanese yogenjū-type wondrous creature attested in kawaraban and related pamphlet culture that emerges from the sea (in canonical accounts) to prophesy about harvests and epidemics and prescribes that its image be drawn and shown to the sick as a protective measure.
Amanojaku
Amanojaku (天邪鬼 / あまのじゃく) is a Japanese yōkai-type being portrayed as a contrarian, heart-reading trickster. Treated in different contexts as a small ogre (ko-oni), a wicked demon (jaki) in Buddhist iconography, and a folkloric spirit that provokes human vice, it appears across regional tales with variable roles from malicious kidnapper to household oddity.
Amefurikozō
Amefurikozō (雨降小僧 or 雨降り小僧) is an Edo-period yōkai figure depicted in classical illustrated and popular print culture as a youthful attendant associated with rain. Classical sources (notably Sekien Toriyama's Konjaku Gazu Zoku Hyakki) present it as a kozō-type servant linked by captional wordplay to a rain deity; later popular literature elaborates its rain-producing role and playful mischief on rainy nights.
Ameonna
Ameonna (雨女, "rain woman") is a figure in Japanese folklore treated as a yōkai associated with rain. Sources depict her both as a rain-calling supernatural being (sometimes helpful in drought) and as a folk label for an unlucky person whom rain seems to follow; a key pictorial source is Toriyama Sekien's Konjaku Hyakki Shūi.
Amorōnagu
Amorōnagu (Amorōnagu / 天降女子) is a tennyo or celestial maiden figure in the folklore of Amami Ōshima (Kagoshima Prefecture, Japan). Attested sources describe her as a heavenly woman who bathes in pools and waterfalls in ravines on the island.
