Ouchi Yoshitaka was a Japanese daimyo who led the Ouchi clan, which at its height ruled most of Chugoku and northern Kyushu, from 1528 to 1551. He spent his early reign fighting the Amago clan, but after a disastrous defeat in an attempt to conquer Izumo province in 1542 withdrew from military affairs and spent the rest of his life in his capital of Yamaguchi. During this time he welcomed the Jesuit missionary Francis Xavier and came up with a plan to transfer the imperial Japanese court from Kyoto to Yamaguchi, but he was deposed and forced to commit suicide. After a few years of decline, the Ouchi were eventually eclipsed by the Mori as the dominant force in Chugoku.
So what if his campaign in Izumo succeeded and the Amago were defeated for good? Where could the Ouchi expand from that point on, and could they march on Kyoto? His wikipedia article says Yoshitaka had good relations with the emperor (hence the plan to move him to Yamaguchi), so perhaps such a move could be seen with a little more legitimacy than an usual armed takeover?
Lastly, could Yoshitaka keep his retainers (such as Mori Motonari) in line?
