Scholarly and folkloric discussion traces the shachihoko to continental roof-ornament motifs. Sources state it evolved from the Chinese Chiwen (a Han-dynasty roof component) and shows affinities with the Vedic/Hindu makara; it was localized in Japan and incorporated into temple and castle roof practice, becoming visible in Nara and Heian periods and widely used by the Sengoku period.
Depicted with the head of a dragon or tiger and the body of a carp covered entirely in black or grey scales. Figures have broad fins and an upward-pointing tail; dorsal fins are often shown with numerous sharp spikes. Roof examples are frequently made so the tail points heavenward and the figure appears oriented toward the roof edge (commonly installed in pairs at roof-ridge ends). Famous decorative instances include the gilded kin shachi at Nagoya Castle (male ~2.62 m high with 112 scales; female ~2.58 m high with 126 scales).
In folklore and architectural belief the shachihoko is credited with aquatic and weather-associated capacities: it is said to be able to swallow and hold a large quantity of water, to summon clouds, and to control rain. These attributed powers explain its use as a roof guardian against fire. Architectural versions sometimes include a spouting hole or are otherwise conceived as capable of emitting water to quench flames; beyond these functional/ritual attributions sources do not present the shachihoko as an individualized moral agent.

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.
