Kuroishi Domain

 was a "tozama" feudal domain under the Tokugawa shogunate of Edo period Japan. It is located in northwestern Mutsu Province, Honshū. Its territory included 2000 "koku" in the area around present-day city of Kuroishi, 1000 "koku" in present-day Hiranani, and 2000 "koku" in what is now part of Ōta, Gunma. The domain was centered at Kuroishi Jin'ya, located in the center of what is now the city of Kuroishi in Aomori Prefecture.
History.
Kuroishi Domain began as a 5,000 "koku" "hatamoto" holding, created in 1656 for Tsugaru Nobufusa (1620–1662), the younger son of Tsugaru Nobuhira, 2nd "daimyō" of Hirosaki Domain. Nobuhira had an elder son (Tsugaru Nobuyoshi) by his first wife, the daughter of Ishida Mitsunari, who had been reduced to concubine status when Nobuhira married the niece of Tokugawa Ieyasu to secure his position vis-à-vis the new Tokugawa bakufu following the death of Toyotomi Hideyoshi. However, his position as the son of a concubine resulted in a split in the ranks of the senior retainers of Tsugaru Domain, with a large faction supporting the younger Tsugaru Nobufusa due to his blood connection to the Tokugawa clan, and due to the fact that he was born as son of Nobuhira's official wife. This resulted in an "O-Ie Sōdō" known as the "Funahashi Sōdō" of 1634, which was only suppressed with assistance by the Tokugawa shogunate and resulted in the exile of a number of Nobufusa's supporters in 1636. Problems arose again in 1647 in what was called the "Tempyō Sōdō", with remaining supporters of Nobufusa demanding that Nobuyoshi retire in favor of Nobufusa, alleging misgovernment through excessive drinking and womanizing. The situation was partly resolved by the creation of a semi-autonomous subsidiary holding for Nobufusa based at Kuroishi. The size of the holding was later reduced to 4000 "koku" after Nobufusa's death.
However, in 1809, the Tokugawa shogunate raised the revenues of Kuroishi by 6000 "koku" during the rule of Tsugaru Chikatari as part of an agreement with Hirosaki "daimyō" Tsugaru Yasuchika over making Hirosaki Domain partially responsible for guarding the northern frontier lands of Ezo (including Karafuto and the Chishima Islands). The total revenues of 10,000 "koku" enabled Tsugaru Chikatari and his successors to enter the ranks of the "daimyō".
The 2nd "daimyō" of Kuroishi Domain, Tsugaru Yukitsugu became "daimyō" of Hirosaki Domain after the forced retirement of Tsugaru Nobuyuki, turning the Kuroishi Domain over to his younger brother Tsugaru Tsuguyasu.
During the Boshin War of the Meiji Restoration, the 4th "daimyō" of Kuroishi Tsugaru Tsugumichi initially supported the Ōuetsu Reppan Dōmei, but then defected to the Imperial cause and joined with the forces of Hirosaki Domain at the Battle of Noheji against the forces of Hachinohe Domain and Morioka Domain. Afterwards, his forces also fought in campaigns in Hokkaidō. In July 1871, with the abolition of the han system, Kuroishi Domain briefly became Kuroishi Prefecture, and was merged into the newly created Aomori Prefecture in September 1871. Under the new Meiji government, Tsugaru Tsugumichi was given the "kazoku" peerage title of "shishaku" (viscount), and later served as a member of the House of Peers.
Bakumatsu period holdings.
Unlike with most domains in the han system, Kuroishi Domain consisted of a continuous territory calculated to provide the assigned "kokudaka", based on periodic cadastral surveys and projected agricultural yields. At the end of the Tokugawa shogunate, the domain consisted of the following holdings:
