The Asahina of Suruga province were descended from Wada Yoshimori (1147-1213), whose 3rd son Yoshihide adopted the name Asahina. They entered the Sengoku Period as a chief Imagawa retainer family and were represented by two branches, one of which produced Asahina Yasutomo while the other was headed by Asahina Nobuoki. The Asahina became especially important after the Imagawa defeat at Okehazama in 1560, for afterwards Imagawa Ujizane came to rely on them to maintain order within his domain. Following the collapse of the Imagawa in 1569, the Asahina became vassals of the conquering Takeda. When the Takeda were in turn destroyed, surviving Asahina entered the service of Tokugawa Ieyasu.
