Chōchin'obake

The name and concept derive from the compound chōchin (提灯), the physical paper- or silk-covered lantern, and obake (お化け / 化け), a term for things that change form. In the documented tradition the chōchin'obake is not primarily an individualized ancestral ghost but an object that has become an obake — an animate lantern. Scholarly and popular sources place the entity in the iconographic field of tool-based yōkai (related to tsukumogami and other animated implements) and note that most references come from pictorial and theatrical sources; there are few localized oral traditions about chōchin'obake, and it is often classified among yōkai that principally 'exist in pictures.'

In the pictorial and theatrical tradition the chōchin'obake is commonly shown as an aged chōchin split at top and bottom so the openings form an open mouth, with a long protruding tongue emerging from that mouth. Typical images show a single large eye in the upper half (sometimes two), and many variants add anthropomorphic features — a human face emerging from the lantern, hands, a torso, or even wings. Lantern bodies appear in bucket-shaped or cylindrical forms in Edo-period prints. Artists and compilers such as Sekien included related entries (e.g., bura-bura), and the motif is echoed in kabuki stage effects and later Meiji–Taishō toys and karuta cards.

Primary, well-attested actions in the sources are startling and frightening people — the chōchin'obake functions as a visual and theatrical scare device. A small number of modern popular retellings (for example Mizuki Shigeru) describe more aggressive powers such as 'sucking out souls,' but such claims are explicitly reported in the sources as later embellishments lacking primary-source corroboration. Older anecdotal material (e.g., a Yamagata tale) links the apparition's appearances to the physical presence of an aged lantern rather than to independent, wide-ranging powers.
