Ogasawara Ujioki

In this Japanese name, the family name is "Ogasawara".

Ogasawara Ujioki (小笠原氏興^?) (1529–1569), also known as Ogasawara Ujikiyo (小笠原氏清^?), was a Japanese samurai of the Sengoku period, who served the Imagawa clan. Ujioki was the eldest son of Ogasawara Haruyoshi and cousin to Ogasawara Nagatoki, the shugo of Shinano Province. He ruled Takatenjin Castle and was also entrusted with Mabusezuka Castle, and supported the Imagawa clan during its expansion westward. After Imagawa Yoshimoto's death at the Battle of Okehazama, Ujioki sided with Tokugawa Ieyasu, and assisted in Ieyasu's campaign against the Imagawa. He took over Mabusezuka and left Takatenjin to his son Ogasawara Nagatada, but died a year later of unknown circumstances.

Ogasawara clan genealogy

The mon of the Ogasawara clan

Ujioki was part of the senior branch of the Ogasawara.^[1]

The Ogasawara clan originated in 12th century Shinano province.^[1] They claim descent from Takeda Yoshikiyo and as part of the Seiwa-Genji.^[2] The great grand-son of Yoshikiyo, Nagakiyo, was the first to take the name Ogasawara. The area controlled by the senior branch of his descendants grew to encompass the entire province of Shinano.^[3] Nagakiyo's grandson, Ogawawara Hidemasa (1569–1615), served Ieyasu; and in 1590, Hidemasa received Koga Domain (20,000 koku) in Shimōsa province. In 1601, Ieyasu transferred Hidemasa to Iida Domain (50,000 koku) in Shinano; then, in 1613, he was able to return to the home of his forebears, Fukashi Castle (80,000 koku),^[2] now known as Matsumoto Castle.^[4]

This senior branch of the fudai Ogasawara from the beginning were daimyō at Fukashi; then, in 1617, the daimyō was transferred to Akashi Domain in Harima province (120,000 koku). In the years spanning 1632 through 1868, the descendants of this branch of the Ogasawara were daimyō at Kokura Domain (150,000 koku)^[5] in Buzen province;^[1] and Ujioki's descendants would be part of this line. The Ogasawara would prosper during the years of Tokugawa shogunate. During the Edo period, the Ogasawara were identified as one of the fudai or insider daimyō clans which were hereditary vassels or allies of the Tokdugawa,^[1] in contrast with the tozama or outsider clans.

The heads of fudai Ogasawara clan branches would be ennobled in the Meiji period.^[2]
