Yashiro Uchiha is the only known member of the Uchiha clan whose hair is not visually black. Despite his old age, Yashiro is one of the top-ranked officers in the Konoha Police Force. It has been seen through flashbacks in the anime that he did not get along well with Itachi. Some of the reasons are that he thought Itachi was a show-off and had an easy time getting into ANBU.
