The Roc is an enormous legendary bird of prey in the popular mythology of the Middle East.
The Roc appears in Arabic geographies and natural history, popularized in Arabian fairy tales and sailors' folklore. Ibn Battuta tells of a mountain hovering in the air over the China Seas, which was the Roc.[1] The story collection One Thousand and One Nights includes tales of Abd al-Rahman and Sinbad the Sailor, both of which include the Roc.
Rokurokubi (ろくろ首, 轆轤首) is a type of Japanese yōkai (apparition). They look almost completely like humans with one of two differences. There is a type whose neck stretches and another whose head detaches and flies around freely (nukekubi). The Rokurokubi appear in classical kaidan (spirit tales) and in yōkai works. It has been suggested, however, that the idea of rokurokubi may have been created for scaring people into staying in past midnight
