Look up in an old Japanese farmhouse and you'll sometimes find them: dark, blotchy stains spread across the wooden ceiling boards, the kind that never quite wipe away. Damp, smoke from the hearth, and decades of humidity are the boring explanation. The tenjōname is the other one, at least in modern yokai books. It is a yokai with a long tongue that licks the ceiling. Twentieth-century writers said the stains were its lick marks.
What does it look like?
Toriyama Sekien drew the tenjōname in Hyakki Tsurezure Bukuro (百器徒然袋, 1784), his fourth and final yokai picture book. It is a strange figure licking the ceiling with a long tongue. Where its better-known relative works low to the ground, the tenjōname is built for height. Its tongue reaches boards well above head level. It isn't drawn with the theatrical menace of an oni or a tengu. It's drawn like a piece of household plumbing gone wrong — a mechanism for reaching somewhere a person can't.
Ceiling grime has its own yokai
The name states the job plainly. 天井 (tenjō) is the ceiling; 嘗 (name) is "to lick." Put together, it's the ceiling-licker, and its behavior doesn't extend past that description.
Sekien's own caption is not about stains. It quotes Tsurezuregusa, section 55: "A high ceiling makes winter cold and the lamp dim." Sekien jokes that the tenjōname causes that cold and gloom. The stain idea came later. Folklorist Fujisawa Morihiko wrote it down in 1929, and Mizuki Shigeru repeated it.
The akaname, which licks the grime out of neglected bathtubs, is a close cousin. Sekien drew it earlier, in Gazu Hyakki Yagyō (1776). Between the two, a household had a yokai for the tub nobody scrubbed and the ceiling nobody could reach.
A joke book of yokai
Hyakki Tsurezure Bukuro is a different kind of catalogue than Sekien's earlier, more famous Gazu Hyakki Yagyō. Its title puns on Yoshida Kenkō's classical essay collection Tsurezuregusa ("Essays in Idleness"), and many of its entries — including a run of tsukumogami, animate household tools — read less like transcriptions of village belief and more like an illustrator's private wit, inventing a face for whatever oddity a house or a language had lying around. The tenjōname fits that pattern closely: there's no recorded oral tradition of ceiling-licking spirits circulating before Sekien's book, no shrine or charm associated with keeping one away. Its body was borrowed too. Scholars match it to an upturned, tongue-out creature in the Muromachi-period Hyakki Yagyō Emaki scrolls.
Where it comes from
That doesn't make it a lesser yokai, only a differently made one. Sekien worked as both an artist and a compiler, drawing on real regional folklore in some entries and inventing plausible-sounding creatures in others, and later scholarship generally treats Hyakki Tsurezure Bukuro's more obscure figures — tenjōname among them — as closer to the second category. Researcher Murakami Kenji suggests Sekien drew on the many ghost stories set around ceilings. The stains were real, too. Damp wood, soot from an open hearth, and poor ventilation genuinely do mark old ceiling boards over the years. Later writers gave the mark a culprit. A Shōwa-era retelling even has a Tatebayashi samurai catch one to clean his castle's ceiling. That story most likely appeared only after Sekien's book.

The tenjōname never developed the following of a kappa or an oni — no proverb, no festival mascot, no cucumber-style tradition attached to it. Its afterlife runs through reference works rather than folk memory: yokai encyclopedias and art books that reproduce Sekien's four picture-book series in full, keeping minor entries like this one on the page long after any household actually blamed its stains on a creature in the rafters. It's the kind of yokai you meet by reading the whole catalogue rather than by hearing the story from a grandparent, which is exactly how Sekien's more inventive entries tend to survive. It also stands as a bronze statue on Mizuki Shigeru Road in Sakaiminato.
