Komoro Domain

 was a feudal domain under the Tokugawa shogunate of Edo period Japan. It is located in Shinano Province, Honshū. The domain was centered at Komoro Castle, located in what is now part of the city of Komoro in Nagano Prefecture. 
History.
The area which later became Komoro Domain was repeated contested between the Uesugi clan, the Takeda clan and the Later Hōjō clan during the Sengoku period, changing hands repeatedly. After Toyotomi Hideyoshi annihilated the Hōjō clan in the Siege of Odawara in 1590, he awarded Komoro as a 50,000 "koku" holding to Sengoku Hidehisa. The marked the start of Komoro Domain. He was confirmed in his status by Tokugawa Ieyasu after the Battle of Sekigahara, and his son, Sengoku Tadamasa was transferred to Ueda Domain in 1622.
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.
In 1702, Makino Yasushige was transferred to Komoro from Yoita Domain in Echigo Province. This at last brought stability to the administration of the domain, as the Makino clan continued to rule until the Meiji restoration. 
During the Boshin War, the 10th "daimyō", Makino Yasumasu quickly supported the imperial side, and participated in the Battle of Hokuetsu and was assigned to guard Usui Pass. However, in September 1869 he was forced to suppress an attempted coup d’etat within his own domain. 
In July 1871, with the abolition of the han system, Komoro Domain briefly became Komoro Prefecture, and was merged into the newly created Nagano Prefecture.

As with most domains in the han system, Komoro Domain consisted of several discontinuous territories calculated to provide the assigned "kokudaka", based on periodic cadastral surveys and projected agricultural yields.
