Kikkawa Sukeharu (1845-August 1865) was the son and heir of Kikkawa Korenao of the Iwakuni Domain. In July 1865, the Iwakuni Domain was restored following Noda Naotaka's samurai rebellion, and the 20-year-old Sukeharu became his 40-year-old father's heir. However, So Koremochi's Choshu Domain army stormed the Iwakuni Domain's capital of Yamaguchi in early August, killing all of the leaders of the rebellion and restoring Choshu rule to the restive province.
