Maeda clan
During the Sengoku period, Nanao Castle was a major stronghold of the Hatakeyama clan, and was contested by the Uesugi clan and Maeda clan. The area became part Kaga Domain controlled by the Maeda clan under the Edo period Tokugawa shogunate, with the exception of some scattered small holdings which retained by the shogunate directly as "tenryō" territory and administered by "hatamoto" for strategic purposes.
