Mr. Oba

Japanese: 大庭氏 - おおばうじ

A medieval samurai family whose main territory was Oba Mikuriya in Sagami Province. Oba Mikuriya was established through the development and donations of Kamakura Gongoro Kagesada, who descended from the Kanmu Heishi clan, and his descendants ruled the area for generations. Kagesada's grandson Kagetada particularly called himself Oba and became the ancestor of the Oba clan. Kagesada's sons, Kageyoshi (Kageyoshi) and Kagechika, both served in Minamoto no Yoshitomo's army during the Hogen Rebellion, and the tales of Kageyoshi's bravery, who survived despite being hit by an arrow from Minamoto no Tametomo, were later celebrated in Kamakura. After the Heiji Rebellion, Kagechika became a vassal of the Taira clan, and when Minamoto no Yoritomo raised an army in 1180 (Jisho 4), he parted ways with Kageyoshi, who had joined Yoritomo early on, and became the commander-in-chief of the Taira clan, defeating Yoritomo's army at Ishibashiyama.

相模国大庭御厨（みくりや）を本領とする中世の武家。桓武平氏の流れをくむ鎌倉権五郎景政の開発･寄進によって成立した大庭御厨は，その子孫が代々現地支配にあたり，景政の孫景忠はとくに大庭を称し大庭氏の祖となる。景忠の子景義(景能)･景親は保元の乱でともに源義朝の軍に属し，このとき源為朝の矢をうけながらも命を長らえた景義の武勇談は，後日鎌倉でもてはやされた。平治の乱後景親は平家に臣従し，1180年(治承4)の源頼朝挙兵に際しては，いちはやく頼朝に参じた景義とたもとをわかって平家方の総大将となり，石橋山で頼朝軍を破った。
