Kikuchi clan
The Kikuchi clan of Hōki Province were based at Odaka-jō (尾高城) and were retainers of the Yukimatsu clan of Izumo Province. The Yukimatsu were vassals of the Yamana clan. One famous figure from the Kikuchi clan of Hōki Province was Kikuchi Otohachi (菊池音八) who is remembered as a "moshō" (a strong bushō) who was killed by Yamanaka Yukimori. In 1560 the Amago clan launched a campaign against the Yamana clan and took control of their land so Narinaga along with his father joined the rebellion to secede from their grasp.
