Obata Domain

Obata Domain (小幡藩, Obata-han^?) was a feudal domain under the Tokugawa shogunate of Edo period Japan, located in Kōzuke Province (modern-day Gunma Prefecture), Japan. It was centered on Obata jin'ya in what is now part of the town of Kanra, Gunma. Obata was ruled through part of its history by the Oda clan, descendents of Oda Nobunaga.

Obata Domain was originally created in 1590 as a 30,000 koku holding for Okudaira Nobumasa, a son-in-law of Tokugawa Ieyasu. After the Battle of Sekigahara in 1601, he was promoted to the 100,000 koku holding of Kanō in Mino province and Obata was reduced to 10,000 koku and given to Mizuno Tadakiyo, a son of Mizuno Tadashige. For his efforts at the Siege of Osaka, he was transferred to the 20,000 koku Kariya Domain in Mikawa Province in 1615. Nagai Naokatsu, another of Ieyasu’s generals noted for his actions ay the Siege of Osaka then briefly ruled from 1616-1617. In 1617, the domain was awarded to Oda Nobuyoshi, the grandson of Oda Nobunaga, and fourth son of Oda Nobukatsu, daimyo of Uda-Matsuyama Domain in Yamato Province. The Oda clan continued to rule Obata over the next seven generations until 1764, when they were transferred to Takahata Domain in Dewa Province. Obata was then awarded to the Okudaira-branch of the Matsudaira clan, who ruled until the end of the Edo period.
