Ayahito (恵仁; 16 March 1800 – 21 February 1846), posthumously honored asEmperor Ninkō (仁孝天皇,Ninkō-tennō), was the 120themperor of Japan according to the traditionalorder of succession.[1][2] Ninkō's reign spanned the years from1817 until his death in 1846, and saw further deterioration of the power of the rulingshōgun.[3] Disasters, which included famine, combined with corruption and increasing Western interference, helped to erode public trust in thebakufu government. Emperor Ninkō revived 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, becameEmperor Kōmei upon Ninkō's death in 1846. While political power at the time still resided with theshōgun, the beginnings of thebakumatsu (end of military government) were at hand.
Before Ninkō's ascension to theChrysanthemum Throne, his personal name (imina) wasAyahito (恵仁).[4] He was born on 16 March 1800 and was the fourth son ofEmperor Kōkaku. He was the only child of sixteen others to survive into adulthood. Ayahito was named as crown prince in 1809, having been adopted by his father's chief wife Imperial PrincessYoshiko (欣子内親王), also known as Shin-Seiwa-in (新清和院). His birth mother was one of his father's concubines named Kajyūji Tadako (勧修寺婧子).
Prince Ayahito was enthroned as Emperor on 31 October 1817, after his father retired from the throne. Following his father the Retired Emperor's wishes, he attempted to revive certain court rituals and practices. These included, among other things, restoring the titletennō, which identified the Emperor. Among Ninkō's innovations was the establishment of theGakushūsho (the predecessor of theGakushūin) for the Court Nobility just outside the Imperial Palace. One major event during his reign was theTenpō famine which lasted from 1833 to 1837. The famine was most severe in northernHonshū and was caused by flooding and cold weather.[5]
Ninkō's reign also sawsome deterioration of theShōgun's power. Damage from the Tenpō famine and other concurring natural disasters shook the faith of the people in the ruling Shōgun. In 1837,Ōshio Heihachirō led a revolt in Osaka against corrupt officials who refused to help feed the impoverished residents of the city. That same year also had anincident take place where an American merchant vessel was driven away by coastal artillery. While order waseventually restored, long term resentment resonated with the commoners against the ruling government. It is unclear though what role, if any, the Emperor played during this period of unrest.
The years of Ninkō's reign are more specifically identified by more than oneera name ornengō.[3] WhileKugyō (公卿) is a collective term for the very few most powerful men attached to the court of theEmperor of Japan in pre-Meiji eras. Even during those years in which the court's actual influence outside the palace walls was minimal, the hierarchic organization persisted.
Emperor Ninkō's family included 7 sons and 8 daughters from various concubines, but only the future Emperor Komei (Komei-tennō), Princess Sumiko (Sumiko-naishinnō) andPrincess Chikako (Chikako-naishinnō) survived beyond childhood.[8]
