Hosokawa Yoriyuki

The son of Hosokawa Yoriharu, Yoriyuki served the shogunate as a military commander, and fought the Yamana clan, and ultimately achieved victory over them in 1361.

He commanded shogunal forces in a number of battles, and while serving under Shōgun Ashikaga Yoshiakira, Yoriyuki killed his cousin, Hosokawa Kiyouji, who had defected to the other side.

The "government under his guidance was stern and just, and unruly vassals were subjected to a discipline not unlike that of the Hōjō Regency in its prime".

[1] Inspired by the policies of the Kenmu era of thirty years earlier, Yoriyuki sought to introduce and maintain discipline and loyalty among the various samurai families and to suppress forces of dissent.

To that end, he promulgated sumptuary laws, placing strict guidelines on the kinds of luxury items samurai could wear, and certain extravagant customs, such as the exchanging of New Year's gifts.
