Kakita Ichiro was the son of Kakita Toshimoko and half-brother of Seppun Toshiken. Rather than take up the blade as his father had done, Ichiro was trained by Kakita Yoshi in the ways of politics. Ichiro planned to kill his father, but was slain by his brother Toshiken when he tried to enact his assassination. After his death Toshiken adopted his son, Kakita Noritoshi.
