盛岡藩
The actual construction work on Morioka Castle was supervised by his Nanbu Nobunao's son, Nanbu Toshinao, who later became the 1st "daimyō" of Morioka Domain, but the castle was not completed until 1633, during the tenure of Nanbu Shigenao, the 2nd "daimyō". However, its three-story "tenshu" burned down only one year later, and was never rebuilt.
