Ayahito Ninko-tenno

Emperor Ninkō (仁孝天皇 Ninkō-tennō, 16 March 1800 – 21 February 1846) was the 120th Emperor of Japan, according to the traditional order of succession. Ninkō's reign spanned the years from 1817 until his death in 1846, and saw further deterioration of the ruling Shōgun's power. Disasters which included famine, combined with corruption and increasing Western interference helped to erode public trust in the bakufu government. Emperor Ninkō attempted to revive certain court rituals and practices upon the wishes of his father. However, it is unknown what role, if any, the Emperor had in the turmoil which occurred during his reign. His family included fifteen children from various concubines, but only three of them lived to adulthood. His fourth son, Imperial Prince Osahito became the next Emperor upon his death in 1846. While political power at the time still resided with the Shōgun, the beginnings of the Bakumatsu (end of military government) were at hand.
