Some scholars identify him with King San in the Book of Song. King San sent messengers to the Song Dynasty at least twice in 421 and 425; and this historical person was succeeded by his younger brother.[4]
Richū had two sons; but he was followed on the throne by his brother, who would become known as Emperor Hanzei. The enthronement of Hanzei by-passed Richū's two sons. Few other details have survived.[7]
This is believed to be the burial mound of Emperor Richū -- in Sakai
Very little is known about the events of Richū's life and reign. Only limited information is available for study prior to the reign of the 29th monarch, Emperor Kimmei.[8]
In his sixth year of his reign, Richū died.
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 Richū.[9]
