Emperor Keikō

was the 12th emperor of Japan, according to the traditional order of succession. Historians consider Emperor Keiko to be a legendary person; and the name Keiko-tenno was created for him posthumously by later generations.
No certain dates can be assigned to this emperor's life or reign. The conventionally accepted names and sequence of the early emperors were not to be confirmed as "traditional" until the reign of Emperor Kammu, who was the 50th monarch of the Yamato dynasty.
Traditional history
Keiko is almost certainly a legend; but the Kojiki and Nihonshoki record his name.
Events of Keiko's life
The limited information about Keiko does not imply that no such person ever existed. Very little information is available for study prior to the reign of the 29th monarch, Emperor Kimmei.
In Kojiki, Keiko sent his one of his sons to Kyushu to fight battles on his behalf. In Nihonshoki, Keiko fought and won these battles against local tribes. According to both sources, he sent Yamatotakeru to Izumo province and eastern provinces to expand his territory.
After his death
This emperor's official name after his death (his posthumous name) was regularized many centuries after the lifetime which was ascribed to Keiko.
The actual site of his grave is not known. According to the Imperial Household Agency, this emperor is venerated at a memorial Shinto shrine (misasagi) at Nara. The kami of Emperor Keiko is also venerated at Anaho jinja in Anaho, Omi province.
