Numazu Domain

[1] In 1601, Ōkubo Tadasuke, a 5000 koku hatamoto was rewarded by Shōgun Tokugawa Ieyasu for his efforts at the Battle of Sekigahara, where he stopped an advance by Toyotomi forces under the famed Sanada Yukimura, by elevation to the rank of daimyō.

He rebuilt Numazu Castle in 1780, and his revenues were increased by 5,000 koku in 1781 when he assumed the post of rōjū .

The second daimyō of Numazu, Mizuno Tadaakira, was also a rōjū, and a close confidant of Tanuma Okitsugu, a senior official in the Tokugawa shogunate.

The 6th daimyō, Mizuno Tadahiro, was a close confidant of Senior Councilor Ii Naosuke.

Tadanori was assigned the short-lived Kikuma Domain in Kazusa province in July 1868 with the same nominal kokudaka.
