Site of Koga Castle, administrative headquarters of Koga Domain
Koga Domain (古河藩 , Koga-han ) was a feudal domain under the Tokugawa shogunate of Edo period Japan . It is located in Shimōsa Province , Honshū . The domain was centered at Koga Castle ,[ 1] located in what is the city of Koga in Ibaraki Prefecture .
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 of Koga Domain, with assessed kokudaka of 30,000 koku .
Afterwards, the domain was reassigned every couple of generations to a large number of fudai daimyō clans, spending the longest time under the control of the Doi 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 peerage system. Koga Domain subsequently became part of 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 , based on periodic cadastral surveys and projected agricultural yields.[ 2] [ 3]
