Kuroishi Domain

Kuroishi Domain (黒石藩, Kuroishi-han^?) 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.

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.
