Tōdaiki / Todaiki

The entity is attested in the Japanese yōkai/bestiary tradition via Toriyama Sekien's Konjaku Hyakki Shūi (as cited in Kappapedia), where it is recorded under the reading toodai ki / toodaki (灯台鬼). Wikidata also links the term to appearances in narrative material such as the Tale of the Heike and other stories (as noted in the supplied excerpts). Beyond these cataloguing and indexing attestations, modern secondary sources and fiction rework the motif: a Monster Wiki entry presents a folkloric-style origin in which a human is transformed by dark magic into a candlestick-like cursed spirit, while Tezuka Osamu's manga Duke Goblin employs a Todaiki image as a giant lighthouse demon within a prophetic dream sequence. The supplied materials do not provide a single canonical medieval origin narrative or a detailed primary-source origin myth.

Primary documentary evidence in the supplied material is classificatory and pictorial rather than descriptive prose. Kappapedia's citation of Sekien records the term with the characters 灯台鬼 and labels it 'Demon with a candlestick,' indicating a hybrid of a lamp/lighthouse/candlestick and a demonic figure in Sekien's plate. The Monster Wiki describes a 'twisted humanoid version of a candlestick' that may be immobile and mute. Tezuka's usage characterizes it as a 'giant lighthouse demon' in a dream. No further consistent visual details (colors, exact anatomy, scale beyond 'giant' in one fiction) are provided in the supplied excerpts.

Accounts in the supplied sources disagree or emphasize different roles rather than a consistent set of powers. Sekien's inclusion in Konjaku Hyakki Shūi places the Tōdaiki among catalogued supernatural beings but the supplied citation gives no explicit powers. The Monster Wiki frames it as a cursed spirit transformed from a human by dark magic and often rendered immobile and mute, used as an ornament by sorcerers or evil spirits (this narrative detail appears only in that modern secondary source). Tezuka's Duke Goblin uses the motif as a visionary or prophetic monstrous figure in a dream sequence. The supplied material does not document traditional abilities such as possession, disease-causing, or weather control, so specific powers remain uncertain in these sources.
