The Mononobe clan was a Japanese aristocratic kin group (uji) of the Kofun period, known for its military opposition to the Soga clan. The Mononobe were opposed to the spread of Buddhism, partly on religious grounds, claiming that the local deities would be offended by the worshiping of foreign deities, but also as the result of feelings of conservatism. The Nakatomi clan, ancestors of the Fujiwara, were also Shinto ritualists allied with the Mononobe in opposition to Buddhism.
