No firm dates can be assigned to this emperor's life or reign, but he is conventionally considered to have reigned from 400 to 405.
Richū is regarded by historians as a "legendary emperor" of the 5th century. The reign of Emperor Kinmei (c. 509 – 571 AD), the 29th emperor, is the first for which contemporary historiography is able to assign verifiable dates; however, the conventionally accepted names and dates of the early emperors were not to be confirmed as "traditional" until the reign of Emperor Kanmu (737–806), the 50th sovereign of the Yamato dynasty.
Richū's contemporary title would not have been tennō, as most historians believe this title was not introduced until the reigns of Emperor Tenmu and Empress Jitō. Rather, it was presumably Sumeramikoto or Amenoshita Shiroshimesu Ōkimi (治天下大王), meaning "the great king who rules all under heaven." Alternatively, Richū might have been referred to as (ヤマト大王/大君) or the "Great King of Yamato."
Richū escaped from Naniwa Place to Isonokami Shrine because of arson. Richū succumbed to disease in his sixth year of reign. His tomb is in Kawachi province, in the middle of present-day Osaka Prefecture. He was succeeded by his younger brother Emperor Hanzei. None of his sons succeeded to the throne, although two grandsons would eventually ascend as Emperor Kenzō and as Emperor Ninken.
The site of Richū's grave is not known. This emperor is traditionally venerated at a memorial Shinto shrine (misasagi) in Sakai, Osaka. The Imperial Household Agency designates this location as Richū's mausoleum. It is formally named Mozu no mimihara no minami no misasagi. It is also identified as the Kami Ishizu Misanzai kofun.
