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.Aston, William George.

Traditional history
Seimu is almost certainly a legend; but the Kojiki and Nihonshoki record his name.Aston, William. (1998). Nihongi. Vol. 1, pp. 188-214.

Events of Seimu's life
The limited information about Seimu 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.Titsingh, pp. 34-36; Brown, pp. 261-262; Varley, pp. 123-124. 

 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 Seimu.

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.
