Omigawa Domain

 was a minor feudal domain under the Tokugawa shogunate of Edo period Japan, located in Shimōsa Province (modern-day Chiba Prefecture), Japan. It was centered on what is now part of the city of Katori. It was ruled for most of its history by the Uchida clan.
History.
Omigawai Domain was created for Matsudaira Ietada in 1594, a close associate of Tokugawa Ieyasu. After his death at the Battle of Sekigahara, the domain passed to Doi Toshikatsu, another close retainer of Tokugawa Ieyasu who played a crucial role in the formation of the Tokugawa shogunate. After he was transferred to Sakura Domain, Omigawa was granted to Andō Shigenobu, a retainer of Tokugawa Hidetada, who had also fought at Sekigahara. On his transfer to Takasaki Domain in 1619, Omigawa Domain reverted to "tenryō" status, directly under the control of the shogunate and administered by a series of " hatamoto "-level officials.
Omigawa Domain was revived in 1724 for Uchida Masachika, who was demoted in status from the 15,000 "koku" "daimyō" of Kanuma Domain in Kōzuke Province to 10,000 " koku" at Omigawa due to crimes committed by his father Uchida Masayuki. He was allowed to build a "jin'ya" in what later become the town of Omigawa, Chiba, where his successors continued to rule until the Meiji Restoration. The final daimyō of Omigawa Domain, Uchida Masanori fought on the imperial side during the Boshin War, and later became an officer in the Imperial Japanese Army, serving in combat during the First Sino-Japanese War.
Holdings at the end of the Edo period.
As with most domains in the han system, Omigawa Domain consisted of several discontinuous territories calculated to provide the assigned "kokudaka", based on periodic cadastral surveys and projected agricultural yields.
