The Ogasawara Clan ( 小笠原氏 Ogasawara-shi) was a samurai clan that descended from the Seiwa Genji .
The Ogasawara served as Shugos (governors) of Shinano Province in the Kamakura, Muromachi, and Azuchi-Momoyama Periods (c. 1185-1600), and as Daimyō (feudal lords) of territories in Kyūshū during the Edo Period (1600-1867).
At the end of the Sengoku Period (late 16th Century), the clan made opposition to Toyotomi Hideyoshi and Tokugawa Ieyasu . But during the Edo Period, the Ogasawara were classified as fudai (Allied Clan) and were hereditary vassals of the Tokugawa , in contrast to the tozama (Outsider Clan).
Ogasawara Clan History
The Ogasawara clan originated in the 12th century in Shinano Prefecture. They are descended from Takeda Yoshikiyo and therefore from Seiwa Genji. Broadly speaking, there are two genealogical lines of the Ogasawara, the Matsuo and the Fukashi , which identify places in Shinano.
The Matsuo line gave rise to the Ogasawara of Echizen, and the Fukashi line to the Ogasawara of Bunzen .
During the Kamakura, Muromachi periods, the clan controlled Shinano Prefecture, while allied clans controlled Awa, Bizen, Bitchū, Iwami, Mikawa, Tōtōmi, and Mutsu Prefectures.
According to some theories, the Miyoshi Clan and the Mizukami Clan were descendants of the Ogasawara Clan.
The clan developed a series of martial arts schools during this period, known as Ogasawara-Ryu , and contributed to the codification of bushido.
Yoshikiyo's great-grandson, Nagakiyo , was the first to bear the Ogasawara name. The area controlled by his descendants grew to encompass the entire Shinano Prefecture .
Nagakiyo's grandson, Ogawawara Hidemasa (1569-1615), was Ieyasu's vassal, and in 1590, received the Domain of Koga (with income of 20,000 koku ) in Shimōsa Prefecture .
In 1601, Ieyasu transferred Hidemasa to the Domain of Iida (50,000 koku ) in Shinano, and in 1613, he is able to return to the home of his ancestors at Fukashi Castle (80,000 koku ), now known as Matsumoto Castle .
