Emperor Sujin
Emperor Suinin is regarded by historians as a "legendary Emperor" as there is insufficient material available for further verification and study. Unlike Emperor Sujin, there is less known about Suinin to possibly support his existence. In either case (fictional or not), the name Suinin"-tennō" was assigned to him posthumously by later generations. His name might have been regularized centuries after the lifetime ascribed to Suinin, possibly during the time in which legends about the origins of the Yamato dynasty were compiled as the chronicles known today as the "Kojiki". Suinin's longevity was also written down by later compilers, who may have unrealistically extended his age to fill in time gaps. While the actual site of Suinin's grave is not known, the Emperor is traditionally venerated at a memorial Shinto shrine ("misasagi") at Nishi-machi, Amagatsuji, Nara City. The Imperial Household Agency designates this location as Suinin's mausoleum, and is formally named "Sugawara no Fushimi no higashi no misasagi".
