Shiro Koritome was the stronghold of the Koritome vassal family. The castle's construction and resources matched that of many Minor Clan strongholds, and their armies equalled the strength of many smaller but more respected families of the Empire. It was located on the road between Kaeru Toshi and Tonfajutsen, defended by watchtowers both on and outside the walls of the castle where the archers could move swiftly from tower to tower.
