Keitai is considered to have ruled the country during the early-6th century, but there is a paucity of information about him. There is insufficient material available for further verification and study.
When Emperor Ankan died, he had no offspring and succession passed to his youngest brother who will come to be known as Emperor Senka. Emperor Senka was elderly at the time of his enthronement; and his reign is said to have endured for only three years.
This emperor is traditionally venerated at a memorial Shinto shrine (misasagi) at Nara. The Imperial Household Agency designates this location as Senka's mausoleum. It is formally named Musa no Tsukisaka no e no misasagi, however, the actual sites of the graves of the early emperors remain problematic, according to some historians and archaeologists.
