Before the Meitoku Rising (ran) in 1391, the Yamana family possessed eleven provinces in western and central Japan which made them the most powerful "shugo" family in the country. Yoshimitsu looked for an excuse to attack them; and when Yamana Mitsuyuki (who was "shugo" over the provinces of Izumo, Tamba, Hoki, and Oki) took possession of some estates belonging to the imperial family in Izumo, Yoshimitsu recalled the ex-"kanrei" Hosokawa Yoriyuki to plan a campaign against Mitsuyuki. The Yamana "shugo" lords Mitsuyuki and Ujikiyo attacked Kyoto, but were severely defeated by the shogunal army in concert with the forces of Ouchi Yoshihiro. The other "shugo" contingents that made up the shōgun's forces numbered no more than three hundred horsemen each. After the campaign, the Yamana were assigned only two provinces, Tajima and Hoki, and the leaders of the rebellion were killed, Ujikiyo in battle and Mitsuyuki through assassination in 1395.
