Ogamo

The Ogamo were a family of eastern Hōki Province, originating in Ogamo district and holding Iwakura Castle. Under the Yamana governors, Ogamo Yukimoto helped defeat Akamatsu Mitsusuke in the Kakitsu rebellion of 1441.

The Amago took Iwakura in the sixteenth century, but the Ogamo later recovered it with Mōri support. After the Nanjō and Ogamo sided against the Mōri, Kikkawa Motonaga captured the castle in 1582; the family recovered it before losing its lands following Sekigahara in 1600.
