Tokugawa Ieshige (January 28, 1712 - July 13, 1761) was the ninth shogun of the Tokugawa shogunate of Japan. Uninterested in government affairs, Ieshige left all decisions in the hands of his chamberlain, Ooka Tadamitsu (1709-1760). He officially retired in 1760 and assumed the title of Ogosho, appointed his first son Tokugawa Ieharu as the 10th shogun, and died the following year. Ieshige's reign was beset by corruption, natural disasters, periods of famine and the emergence of the mercantile class, and his clumsiness in dealing with these issues greatly weakened the rule of Tokugawa.
