Ōkubo Tadatomo
Biography. Ōkubo Tadatomo was a son of Ōkubo Noritaka, a 6000 "koku" "hatamoto" in the service of the Nanbu clan and descendant of Ōkubo Tadachika. Due to the early death of his father, Tadatomo was adopted by his brother Ōkubo Tadamoto, the 1st daimyō of Karatsu, whom he served as a page. Tadatomo became daimyō of Karatsu on the death of his brother in 1670. He was appointed as a "rōjū" under "shōgun" 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. In 1684, the "Tairō" Hotta Masatoshi was assassinated by "wakadoshiyori" Inaba Masayasu, and his cousin Inaba Masamichi was punished by demotion from Odawara Domain to the much smaller Takada Domain in Echigo Province. 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. Tadatomo never officially married, and his son and heir Ōkubo Tadamasu was the son of a concubine.
