新井白石
Although "shōgun" Ietsugu assumed the role as formal head of the "bakufu", he was still a toddler. As he was not old or able enough to rule, he was put under the protection and advice of Confucian scholar Arai Hakuseki. Two problems were addressed during Ietsugu's reign: currency reform and foreign trade in Kyūshū. Ietsugu did not take much care of the country's matters; and his advisors, namely Arai Hakuseki, addressed them.
