Oyumi Domain (生実藩 Oyumi-han?) was a Japanese domain of the Edo period, located in Shimōsa Province (modern-day Chiba Prefecture), Japan. The site of the Oyumi jin'ya is now under a residential area of the city of Chiba. The domain was ruled through its entire history by the Morikawa clan.
Oyumi Domain was created in February 1627, when Morikawa Shigetoshi, a hatamoto in the service of Shogun Tokugawa Hidetada acquired holdings in Sagami, Kazusa and Shimōsa Provinces with revenues exceeding the 10,000 koku necessary to qualify as a daimyō. He was allowed to build a jin'ya on the site of the Sengoku period Oyumi Castle. He later rose to the post of rōjū, and committed junshi on the death of Tokugawa Hidetada. His successors continued to rule Oyumi Domain until the Meiji Restoration.
Holdings at the end of the Edo period
As with most domains in the han system, Oyumi Domain consisted of several discontinuous territories calculated to provide the assigned kokudaka, based on periodic cadastral surveys and projected agricultural yields. The domain was centered on what is now Chuo Ward and Midori Ward of the city of Chiba.
