Ōuchi Yoshioki
Ōuchi Yoshioki became a sengoku daimyō of Suō Province and served as the 15th head of the Ōuchi clan. Yoshioki was born early in the Sengoku period, the son of Ōuchi Masahiro, shugo of Suō Province and the 14th head of the Ōuchi clan. The first character in Yoshioki's name originated from Ashikaga Yoshihisa, the ninth shōgun in the Muromachi bakufu. In 1492, Masahiro ordered Yoshioki to join the battle against Rokkaku Takayori, a sengoku daimyō from southern Ōmi Province. In the midst of this engagement in 1493, an incident known as the Meiō no seihen occurred, by which Hosokawa Masamoto, a kanrei, or deputy, held the shōgun, Ashikaga Yoshiki, in confinement. Yoshioki withdrew his men from the battle to Hyōgo in Settsu Province to wait for the outcome of the event, which resulted in Yoshiki being deposed and replaced by Ashikaga Yoshizumi. Yoshioki's younger sister was abducted while staying in Kyōto in an area under the control of Takeda Motonobu, an ally of Hosokawa Masamoto. Masamoto took her hostage as leverage against Masahiro in his support for Yoshiki. Masahiro then ordered close associates of Yoshioki to commit seppuku. This may have been as retribution for what he viewed as Yoshioki's tepid response to the pressure exerted upon him by Masamoto and his retainers. Nevertheless, Yoshioki's decision to withdraw his forces was well-received by the hikan, or administrators, in his birthplace of Kyōto, building relationships that benefit him later at the time of his succession to Masahiro.
