Life
Family and early life
Born in 1641, he was the eldest son of Kira Yoshifuyu. His mother was a member of the high-ranking Sakai clan. On the death of his father in 1668, Yoshinaka became the 17th head of the household, inheriting lands evaluated at 4200 koku. His wife was from the Uesugi clan, and his eldest son was adopted by Uesugi Tsunakatsu, the head of the Dewa Yonezawa han, taking the name Tsunanori. Yoshinaka named his second son as his heir, but when that heir died, Yoshinaka adopted Tsunanori's second son, strengthening the connection between the Kira and the Uesugi.
Career
As a kōke, Kira oversaw matters of protocol. In 1701, he was assigned the task of tutoring Asano Naganori in matters of protocol in preparation for an upcoming visit by representatives of the Emperor. According to the stories, Kira was corrupt and demanded bribes for the tutoring, which Asano refused to pay. Kira then began to publicly insult Asano, calling him an ignorant and unmannered rural boor. On the day when the envoys were scheduled to meet the shōgun at Edo Castle, Asano drew his wakizashi and attempted to kill Kira in retaliation for the insults. For this, Asano was sentenced to commit seppuku, his house abolished and his retainers branded rōnin, while Kira went unpunished.
