Numazu Domain

Numazu Domain (沼津藩, Numazu-han) was a feudal domain under the Tokugawa shogunate of Edo period Japan located in Suruga Province. It was centered on Numazu Castle in what is now the city of Numazu, in modern-day Shizuoka Prefecture.^[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 was assigned the territory of Numazu, to the east of Sunpu, to be his domain, with revenues of 40,000 koku. However, when he died without heirs in 1617, the domain reverted to the Tokugawa Shogunate.

The domain was revived in April 1777, when the former wakadoshiyori Mizuno Tadatomo was transferred from Ohama Domain in Mikawa province, and assigned revenues of 20,000 koku. He rebuilt Numazu Castle in 1780, and his revenues were increased by 5,000 koku in 1781 when he assumed the post of rōjū . He received another 5,000 koku increase in 1785.

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. Through this connection, he secured an increase in the revenues of Numazu Domain by an additional 10,000 koku in 1821 and another 10,000 koku in 1829.

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

However, during the Bakumatsu period, the 8th (and final) daimyō, Mizuno Tadanori, sided with the new Meiji government in the Boshin War of the Meiji Restoration. His domain was abolished with the creation of Shizuoka Domain for the retired ex-Shōgun Tokugawa Yoshinobu. The holdings of the domain in Suruga province were transferred to Shizuoka Domain, and the holdings in Izu province with transferred to Nirayama Prefecture. Tadanori was assigned the short-lived Kikuma Domain in Kazusa province in July 1868 with the same nominal kokudaka.

In 1871, the territory of former Numazu Domain became part of Shizuoka Prefecture.^[2]

As with most domains in the han system, Numazu Domain consisted of several discontinuous territories calculated to provide the assigned kokudaka, based on periodic cadastral surveys and projected agricultural yields.^[3][4]
