Tokugawa Ieyoshi (徳川 家慶, June 22, 1793–July 27, 1853; r.1837–1853) was the 12th shogun of the Tokugawa shogunate of Japan. He was the second son of the 11th shogun, Tokugawa Ienari, and appointed Mizuno Tadakuni to conduct the Tenpo reform. Shortly after the arrival of U.S. Commodore Matthew Perry, in 1853, whose purpose was to negotiate a treaty allowing American trade with Japan, Tokugawa Ieyoshi died, and was succeeded by his third son Tokugawa Iesada. The following year the Tokugawa shogunate was forced to accept the American demands after signing the Convention of Kanagawa.
