Arai Hakuseki
In 1712, Shogun Ienobu died, and was succeeded by his son, the boy-"shōgun" Tokugawa Ietsugu. Yorimasa decided that he could not rely on conservative Confucianists like Arai Hakuseki in Edo and did what he could to stabilize Kii Domain. Before he could implement changes, "shōgun" Ietsugu died in early 1716. He was only seven years old, and died without an heir, rule thus shogunate selected the next "shōgun" from one of the cadet lines.
