Daidarabotchi (ダイダラボッチ, 大座法師) was a gigantic type of yōkai in Japanese mythology, sometimes said to pose as a mountain range when sleeping.
The Hitachi no Kuni Fudoki, a recording of the imperial customs in the Hitachi Province compiled in the 8th century, also told of a Daidarabotchi living on a hill west of a post office of Hiratsu Ogushi who fed on giant clams from the beach, piling the shells on top of a hill.
In Mito, Ibaraki, a 15-meter statue was erected in Ogushi Kaizuka Park to commemorate the yōkai and its myths.
Having the strength of a giant, he performed Kuni-biki, pulling land from Silla with ropes, to increase the size of his territory.
The Daidarabotchi was also said to reside at Mount Togakushi, where there exists a pond on its south side bearing its name.
