Oyumi Domain

Oyumi Domain (生実藩, Oyumi-han^?) was a Japanese domain of the Edo period, located in Shimōsa Province (modern-day Chiba Prefecture), Japan. It was centered on what is now Chuo Ward and Midori Ward of the city of Chiba. It was ruled for the entirety of its 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 his successors continued to rule Oyumi Domain until the Meiji Restoration.
