Koga Domain History
During the Muromachi period , Koga was the seat of the Kantō kubō , under the Ashikaga clan , who vied with the Uesugi clan and with the Later Hōjō clan for control of eastern Japan. Ashikaga Ujinohime was the last Koga-kubo and owner of Koga domain of the Ashikaga lineage.
When Toyotomi Hideyoshi defeated the Hōjō at the Siege of Odawara , the area fell into his hands, and was subsequently assigned (along with the rest of the Kantō region ) to Tokugawa Ieyasu . Ieyasu assigned Koga Castle to his grandson-in-law, Ogasawara Hidemasa as daimyō kokudaka koku
Afterwards, the domain was reassigned every couple of generations to a large number of fudai daimyōDoi clan (1633–1681, 1762–1871).
During the Boshin War , the Tokugawa shogunate ordered the domain to provide guards on the foreign settlement at Yokohama . However, the domain capitulated almost immediately on the approach of the imperial forces. The final daimyō of Koga, Doi Toshitomo , served as domain governor until 1871, and was awarded the title of shishaku (marquis ) under the kazoku Ibaraki Prefecture .
Bakumatsu period holdings
As with most domains in the han system , Koga Domain consisted of several discontinuous territories calculated to provide the assigned kokudaka cadastral surveys and projected agricultural yields.[ 2] [ 3]
