大久保 忠朝
Ōkubo Tadatomo was a son of Ōkubo Noritaka, a 6000 koku hatamoto in the service of the Nambu clan and descendant of Ōkubo Tadachika.
He was assigned by the Tokugawa shogunate to Karatsu Domain, Sakura Domain, and finally to Odawara Domain in Sagami Province, (modern-day Kanagawa Prefecture), where his descendants remained until the Meiji Restoration. He was appointed as a rōjū under Shogun Tokugawa Ietsuna in 1677. His courtesy title was changed at that time from Dewa no Kami to Kaga no Kami, and his court ranking elevated from lower 5th to lower 4th.
The following year, he was reassigned to Sakura Domain in Kazusa Province.
His revenues were increased by 10,000 koku in 1680 and his courtesy title was elevated to Chamberlain. Ōkubo Tadatomo was assigned to Odawara in his place in 1686.
His revenues were further increased by an additional 10,000 koku in 1698, reaching a total 113,000 koku. He retired from public life in 1698 and died in 1712.
His grave is at the temple of Saisho-ji in Setagaya, Tokyo.
The Shiba Rikyu gardens in Tokyo were originally built on the Edo residence of Ōkubo Tadatomo in 1678, when he entertained Shogun Tokugawa Ieshige.
