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.
