Emperor Ingyō

Emperor Ingyō (允恭天皇, Ingyō-tennō) was the 19th Emperor of Japan, according to the traditional order of succession. Both the Kojiki, and the Nihon Shoki (collectively known as the Kiki) recorded events that took place during Ingyō's alleged lifetime. No firm dates can be assigned to this Emperor's life or reign, but he is conventionally considered to have reigned from 410 to 453.

While the location of Ingyō's grave (if any) is unknown, he is traditionally venerated at a memorial Shinto tomb.
