Emperor Ninkō

Before Ninkō's ascension to the Chrysanthemum Throne, his personal name (imina) was Ayahito (恵仁).[4] He was born on 16 March 1800 and was the fourth son of Emperor 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 Princess Yoshiko (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 title tennō, which identified the Emperor. Among Ninkō's innovations was the establishment of the Gakushūsho (the predecessor of the Gakushūin) for the Court Nobility just outside the Imperial Palace. One major event during his reign was the Tenpō famine which lasted from 1833 to 1837. The famine was most severe in northern Honshū and was caused by flooding and cold weather.[5] Ninkō's reign also saw some deterioration of the Shōgun's power. The Tenpō famine and other concurring natural disasters hit hard, and 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 an incident take place where an American merchant vessel was driven away by coastal artillery. While order was eventually 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.

Emperor Ninkō died on 21 February 1846 and was enshrined in the Imperial mausoleum, Nochi no Tsukinowa no Higashiyama no misasagi (後月輪東山陵), which is at Sennyū-ji in Higashiyama-ku, Kyoto. Also enshrined in Tsuki no wa no misasagi, at Sennyū-ji are this Emperor's immediate Imperial predecessors since Emperor Go-Mizunoo – Meishō, Go-Kōmyō, Go-Sai, Reigen, Higashiyama, Nakamikado, Sakuramachi, Momozono, Go-Sakuramachi, Go-Momozono and Kōkaku. The shrine complex also encompasses the misasagi of Ninkō's immediate successor – Kōmei.[6] Empress Dowager Yoshikō is also entombed at this Imperial mausoleum complex.[7]
