Yoshida Domain
The former Hosokawa landholding in Bizen was partitioned; Ogasawara Tadazane, who had ruled the Akashi Domain of Harima Province, was granted 150,000 "koku" of land in northern Bizen, with the territory's seat of government being placed at Kokura Castle. The secondary castle of Nakatsu became the center of the new Nakatsu Domain, which was granted to Tadazane's nephew Ogasawara Nagatsugu. Simultaneously, Tadazane's younger brother Ogasawara Tadatomo, who had been a hatamoto, was given Kitsuki Castle and the surrounding 40,000 "koku" worth of territory, making him a "daimyō". Tadatomo retained rulership of Kitsuki until 1645, when he was moved to the Yoshida Domain of Mikawa Province.
