In the following year of 1051, the Abe clan (Oshu Province) tried to expand their region of authority beyond the Koromo-gawa River; Narito, the Mutsu no kami (Governor of Mutsu Province), joined forces with TAIRA no Shigenari, Akitajo no suke (provincial governor of Akita-jo Castle in Dewa Province) and others in an attempt to control them, but suffered a crushing loss in Onikiribe and was replaced.
翌年の永承6年（1051年）、安倍氏(奥州)が衣川の柵を越え勢力圏を拡大しようとしたため、陸奥守だった登任は、秋田城介平重成らと安倍氏を討伐しようするが、逆に鬼切部で大敗を喫し更迭された。
