Numazu Domain

This was a domain that ruled the Numazu region of Suruga Province (Shizuoka Prefecture). In 1601 (Keicho 6), Okubo Tadasuke moved from Kazusa Mobara to Sanmaibashi Castle (Numazu Old Castle), which had been there since the end of the Sengoku period, and established the domain with 20,000 koku of rice. However, in 1613, Tadasuke had no heir and the domain was dissolved. After that, this area was sometimes the territory of Tokugawa Yorinobu and Tokugawa Tadanaga, but most of it continued to be controlled by the shogunate's magistrate.

In 1777 (An'ei 6), Mizuno Tadatomo, a lord of Ohama in Mikawa with a stipend of 13,000 koku, was promoted from young councilor to chamberlain, and given an additional stipend of 7,000 koku and 3,000 ryo for castle construction funds, which allowed him to build Numazu Shinjo Castle and enter the domain, restoring it to a fief of 20,000 koku. The Mizuno clan was the family of Tokugawa Ieyasu's mother, Denzuin, and had been the lord of Matsumoto Domain in Shinano for generations, starting with Tadatomo's direct ancestor, Tadakiyo, but during the reign of Tadatsune, he was stripped of his fief after he engaged in a sword attack on Mori Moronari in the castle. The family name alone was passed down to his uncle, Tadayoshi (Tadatomo's father). Tadatamo started out as a servant of the Shogun's heir Takechiyo (Ieshige), and was promoted to chamberlain and then senior councilor while remaining a chamberlain, supporting the Tanuma era (30,000 koku). His adopted son, Tadanari (chief senior councilor), recoined currency and earned more than 600,000 ryo in profits (50,000 koku). After him, Tadatamo was succeeded by Tadayori, Tadayu, Tadanaga, Tadahiro, Tadanobu, and Tadanori, leading to the Meiji era. During this time, Numazu Domain's Western studies led to the creation of works such as the Yochi Navigation Chart, Mizuno Family Records, and Mizuno Tadataka Family Records. In 1868 (Keio 4), with the establishment of the Sunpu Domain by the Tokugawa family, he was transferred to Kikuma in Kazusa.

駿河(するが)国（静岡県）沼津地方を領有した藩。1601年（慶長6）大久保忠佐(ただすけ)が上総茂原(かずさもばら)から、戦国末以来の三枚橋(さんまいばし)城（沼津古城）に入り2万石で立藩したが、1613年忠佐に嗣子(しし)がなく絶藩。以後この地は徳川頼宣(よりのぶ)、徳川忠長らの領地となったこともあったが、大部分は幕府の代官支配が続いた。

　1777年（安永6）三河大浜1万3000石の水野忠友が、若年寄から側用人(そばようにん)に進み、7000石の加増と3000両の築城資金を与えられて沼津新城を築いて入封、再立藩した（領地高2万石）。水野氏は、徳川家康の生母伝通院(でんずういん)の生家であり、忠友の直接の祖忠清以降は代々信濃(しなの)松本藩主であったが、忠恒(ただつね)のとき城中で毛利師就(もろなり)に対し刃傷(にんじょう)に及び除封となった。家名だけは伯父忠穀(ただよし)（忠友の父）によって継承。忠友は将軍世子(せいし)竹千代（家重(いえしげ)）の御伽(おとぎ)から身をおこして昇進し、側用人のまま侍従、老中に進み、田沼時代を支えた（高3万石）。養子忠成(ただあきら)（老中首座）は貨幣改鋳を行い益金60万両余を得た（高5万石）。以後、忠義、忠武、忠良(ただなが)、忠寛(ただひろ)、忠誠(ただのぶ)、忠敬(ただのり)と続き明治に至った。この間、沼津藩洋学の成果の一つ『輿地(よち)航海図』『水野家記録』『水野忠敬家記』などが残されている。1868年（慶応4）徳川宗家の駿府(すんぷ)藩創置に伴い、上総菊間(きくま)へ転封となった。
