After Tadayoshi came of age and became the lord of the castle, Ietada was again moved to a new fief, this time to Omigawa, Shimousa Province (present day Katori City, Chiba Prefecture), where he established a base at Kamidai-jo Castle (present day Sakurai, Katori City).
その後、忠吉が正式に城主になると改めて下総国小見川（現在の千葉県香取市）に移封され、上代城（同市櫻井）を本拠とした。
