三河吉田藩
Tsugaru Yukitsugu was born as Matsudaira Yukinori, the 5th son of Matsudaira Nobuakira, the "daimyō" of Yoshida Domain in Mikawa Province. He was adopted on June 5, 1821, as the heir to Tsugaru Chikatari, the "daimyō" of Kuroishi Domain. On his adoptive father’s retirement, as Tsugaru Yukinori, he became the 2nd "daimyō" of Kuroishi Domain from 1825 to 1839. He was known as an intelligent ruler, and worked for the restoration of the domain's finances during the political and agricultural crisis of the Tenpō era. After the Tokugawa shogunate forced Tsugaru Nobuyuki of Hirosaki Domain into retirement over allegations of gross misrule, Yukinori was ordered to change his name to Tsugaru Yukitsugu and to take his place as the 11th "daimyō" of Hirosaki. He turned the rule of Kuroishi Domain over to his brother, Tsugaru Tsuguyasu.
