Ichiman is a child of one or two, the eldest son of the head of the house and therefore, by birth, the next lord of Kamakura.
His mother's family, the Hiki, are rich in offices and close to Yoriie. For the Hōjō his existence is the problem: if Yoriie dies or is set aside while Ichiman is small, the Hiki rule in his name. On the likely course the Hōjō end the question in 1203: Ichiman is killed with the Hiki (the Azuma Kagami and the Gukanshō disagree on who killed him).
