The Biwa‑bokuboku belongs to the tsukumogami tradition: man‑made household artifacts that, by folklore, may become animate after long existence or when they reach an advanced age (sources commonly cite the motif of objects becoming alive after roughly 100 years). The Biwa‑bokuboku specifically is a biwa that acquires awareness and anthropomorphic form through long use, long neglect, or the passage of time as described in tsukumogami accounts.
Described in the sources as an anthropomorphic being with the head of a traditional biwa and often pictured wearing precious kimono. Accounts specifically note it 'sits calmly in a tatami room, singing and plinking,' and it is compared to similar instrument yōkai such as the koto‑furunushi. Sources do not specify exact size beyond its depiction within household rooms.
Sources describe the Biwa‑bokuboku as coming to life at night and singing and plinking its instrument‑head while lamenting neglect by a former owner. It is characterized as ambivalent rather than uniformly hostile: its actions center on noisy complaint and socializing. Alternative accounts note that Biwa‑bokuboku may meet other tsukumogami, hold noisy parties, dance through houses, or leave home to seek others with whom to commiserate. There are no sources in the provided material that attribute overtly harmful supernatural powers or standardized possession rituals to it.

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.
Amanozako
Amanozako is a Japanese divine/monstrous figure described in classical summaries as a furious, contrarian kami produced from the ferocious aspect (ara-mitama) of the storm-god Susanoo; later glosses present her as an ancestor-figure for ill-tempered yōkai such as tengu and amanojaku.
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.
