Daidarabotchi

Sources present Daidarabotchi both as a type of gigantic yōkai and in specific localised legendary figures recorded in classical place-records. Hitachi no Kuni Fudoki (as summarized in modern sources) relates a Daidarabotchi living near Hiratsu Ogushi who fed on giant clams and piled their shells into a hill; Izumo no Kuni Fudoki recounts Ōmitsunu, a giant-strength king linked thematically to land-pulling (kuni-biki). Across accounts the figure functions as a mythic explanation for conspicuous landforms rather than a single canonical life-story.

Daidarabotchi is described in the tradition as an enormous humanoid or giant yōkai whose size is great enough that its sleeping body could be mistaken for a mountain range and whose footprints became lakes and ponds. Some modern glosses and derivative depictions describe a bald-monk-like silhouette (rendering the kanji 大座法師 as 'big seated monk'), but the core folkloric descriptions emphasize vast humanoid scale and landscape equivalence rather than standardized iconography.

Primary attributed abilities are geological in scale: creating lakes and ponds with its footprints, moving or piling up mountains and hills, and altering coastal material (for example, piling clam shells into a hill). Legends credit prodigious physical strength and earth-shaping agency; in related tradition Ōmitsunu performs kuni-biki (land-pulling) to enlarge territory. In some regional accounts (notably Ibaraki) the being uses its strength benevolently to assist people by moving mountains.
