Tanaka Domain
Komoro was part of the holdings of Kōfu Domain from 1622-1624, but was revived as an independent domain for Matsudaira Norinaga from 1624-1647. On his death without an heir, the domain was placed under Matsumoto Domain for a year, until the transfer of Aoyama Munetoshi, who was raised from "hatamoto" status. He subsequently served as "Osaka jōdai" from 1662, and Komoro was given to Sakai Tadayoshi, formerly of Isesaki Domain. Sakai was demoted to Tanaka Domain in Suruga Province in 1679. The next ruler of Komoro was Nishio Tadanari, formerly of Tanaka Domain. He made great efforts to undo the damage caused by the misgovernment of Sakai Tadayoshi, but was transferred to Yokosuka Domain in 1682. Komoro was then given to a junior branch of the Matsudaira clan from 1679 to 1702.
