The civil war of the Keitai and Kinmeicho dynasties (継体・欽明朝の内乱, Keitai Kinmeicho no nairan) is a hypothetical civil war in Japanese history. It is based on the assumption that the death of Emperor Keitai in the first half of the 6th century resulted in a struggle over the succession to the throne, but remains speculative as there are unnatural points in the documents recording the history of the time. The assumed year of the outbreak is specifically set as 531 CE, the year of Emperor Keitai's death according to the Chronicles of Japan. The possible conflict is also known as Shinigai no Hen (辛亥の変).
