薩長同盟
During the Boshin War, the domain quickly supported the Satchō Alliance. After the Battle of Ueno, the final "daimyō" of Takaoka, Inoue Masanori, submitted to the Meiji government. He was appointed domain governor under the new administration, until the abolition of the han system in July 1871 and subsequently served in the police forces of the new government and became a viscount under the "kazoku" peerage. The former Takaoka Domain was absorbed into the new Chiba Prefecture.
