The Ōkubo clan (大久保氏 Ōkubo-shi?) were a samurai kin group which rose to prominence in the Sengoku period and the Edo periods.[1] Under the Tokugawa shogunate, the Ōkubo, as hereditary vassels of the Tokugawa clan, were classified as one of the fudai daimyō clans.[2]

Ōkubo clan genealogy[edit]

The Ōkubo clan traces its origins to 16th century Mikawa province.[2] The Ōkubo claimed descent from the Utsunomiya clan, descendants of Fujiwara no Michikane (955–995).[3] Ōkubo Tadatoshi (1499–1581) and his younger brother Ōkubo Tadakazu (1511–1583) were the first to abandon the Utaunomiya name for "Ōkubo". Both brothers were among the seven closest retainers of Matsudaira Hirotada, the father of Tokugawa Ieyasu.

Main branch[edit]

The head of this clan, Ōkubo Tadanori line was ennobled as a viscount ("shishaku") in the kazoku peerage system.[3]

Cadet lines[edit]

  • A cadet branch was created in 1601 for Ōkubo Tadasuke (1537–1613), the second son of Ōkubo Tadakazu, who had served as a general in the armies of Tokugawa Ieyasu. Ōkubo Tadasuke was given Numazu Castle and assigned Numazu Domain (20,000 koku) in Suruga province; however, he died without leaving any heirs, and the domain reverted to the shogunate.[3]
  • A cadet branch of the Ōkubo was created in 1684. The descendants of Ōkubo Tadatame (1554–1616), the sixth son of Ōkubo Tadakazu, has served as hatamoto to the Tokugawa shogunate. In 1687, Ōkubo Tadataka had amassed a revenue base of 10,000 koku, which qualified him to join the ranks of the daimyō. His son, Ōkubo Tsuneharu (1675–1728) was assigned to Karasuyama Domain (30,000 koku) in Shimotsuke province in 1725, where his descendants remained until the Meiji restoration. The head of this clan line, Ōkubo Tadayori, was ennobled as a "Viscount" in the Meiji period.[3]
  • A cadet branch of the Ōkubo was created in 1706. This clan line was instituted for the descendants of Ōkubo Norihiro (1657–1737), who were installed at Ogino-Yamanaka Domain (13,000 koku) in Sagami province from 1718 through 1868. The head of this clan line was ennobled as a "Viscount" in the Meiji period.[3]

Indirect Ōkubo kazoku lines[edit]

  • In 1877, a former samurai from Suruga Province, Ōkubo Ichio (1817–1888) was ennobled as a "Viscount" under the kazoku system.[3] Ōkubo Ichio had served as councilor to the last five Tokugawa Shoguns, and during the Boshin War, had served as an emissary for Tokugawa Yoshinobu to negotiate the surrender of Edo to imperial forces. Under the Meiji government, he served as appointed governor of Shizuoka (1870) and Kyoto (1875), and as a member of the Genrōin (1877). He was also known as Ōkubo Tadahiro.
