After Buddhism spread in Japan, Kaya no Hime began to be considered to have been the mother of the god of fog, of the god of darkness and of the god of worldly desires, therefore, Nozuchi began to be considered to be a god bearing various specters, and Nozuchi itself was gradually considered to be a specter or a govlin.
後に仏教が普及すると、カヤノヒメが霧の神、暗闇の神、惑わしの神を産んだとされることから、野槌は妖怪変化を産む神とみなされ、野槌自体も次第に妖怪視された。
