Tenjōname

Tenjōname, literally "ceiling-licker," is a yōkai of the Japanese Edo period depicted as a tall, gaunt, faintly humanoid figure with an extraordinarily long tongue, shown clinging to or reaching along the ceiling of an old building. Its primary attestation is pictorial: it appears in the illustrated yōkai catalogues associated with Toriyama Sekien and similar eighteenth-century print compilations, which paired a stock image with a brief explanatory caption rather than any developed story. Physically it is drawn as spindly and shadow-dark, suited to occupying the high, dim corners of a traditional wooden building where a ceiling would need to be reached by something unnaturally elongated.

What the tradition credits it with doing is narrow: its long tongue is offered as the cause of the cold patches, dark stains, or grime visible high on the ceilings of old temples and houses, phenomena that in an ordinary building come from damp, soot, or age. Rather than being an encountered threat with a story of pursuit or negotiation, tenjōname functions as an explanatory figure attached after the fact to a household observation, and modern scholarship on yōkai treats it explicitly as an example of the type: an image and a caption doing the work a folk narrative would otherwise do. No source gives it speech, motive, or any interaction with a human beyond the implied nightly visit to the ceiling.

The material here is genuinely thin, and it is worth saying so plainly: there is little to no evidence of an oral folk narrative about tenjōname independent of the illustrated catalogues, and its status as inherited "folklore" versus an artist's invention explaining a household phenomenon is an open question among yōkai scholars rather than a settled point. Later compendia, including modern English-language encyclopedias, repeat and stabilize the image, but they draw on the same pictorial tradition rather than adding independently attested stories, sightings, or regional variants. What can be said with confidence is limited to the visual type, its ceiling-licking action, and its association with the stains it explains.

The paragraphs below are extrapolated; no source supports them.

Read as a personality, tenjōname resists characterization more than most figures in this tranche, since almost nothing beyond a single repeated action is attested. What little there is suggests something solitary and fixed in habit rather than purposeful — a creature defined by one recurring, almost mechanical behavior with no recorded awareness of or interest in the household beneath it. There is no sign of malice, communication, or reaction to being noticed; if anything, the absence of any human confrontation in the material implies indifference rather than menace. This reading should be treated as considerably more speculative than the others in this batch, given how little behavior the sources actually supply.
