[5] According to the Shinto religion and Buddhism in Japan, Emperor Ōjin is the divine spirit of the deity Hachiman (八幡神).
The circumstances surrounding the future emperor's birth are controversial as they involve a supposed invasion of the Korean Peninsula as well as a biologically impossible gestation period (3 years).
Empress Jingū then became a de facto ruler who allegedly invaded a "promised land" (Korea) out of revenge, then returned three years later to the Japanese mainland to give birth.
The records state that Ōjin was born to Empress Jingū in Tsukushi Province sometime in 201 AD, and was given the name Homutawake (誉田別尊).
It is certainly possible that he was a chieftain or local clan leader, and that the polity he ruled would have only encompassed a small portion of modern-day Japan.
The Imperial Household Agency designates this location as Ōjin's mausoleum, and is formally named Eega no Mofushi no oka no misasagi.
Unless otherwise noted (as BC), years are in CE / AD * Imperial Consort and Regent Empress Jingū is not traditionally listed.
