Ogasawara clan
In the late period of Kamakura era the name of the clan had been already seen here and there in Awa Province. It was a descendant of Ogasawara clan, which was Awa shugo. In the early period of the Northern and Southern Courts (Japan), the clan acted on the Southern Court (Japan), and there was a period that it conflicted with Hosokawa clan on the Northern Court (Japan). However, with the Southern Court losing ground and Hosokawa clan growing its influence in the bakufu (the Northern Court), the clan surrendered to the bakufu.
