Emperor Ōjin

Emperor Ōjin (応神天皇 Ōjin Tennō), or rather Ojin okimi was the 15th imperial ruler of Japan, according to the traditional order of succession. No firm date can be assigned to this emperor.

It is somewhat probable that he (or the chieftain upon whose life the legend about Ojin is built) flourished in early 5th century CE.

His name when alive, appears to have been Honodawake no Mikoto, Fondano Miko no Mikoto/ Otomowake no Mikoto/ Humudawake no Mikoto.

He is the earliest historical emperor. He has been deified as Hachiman Daimyōjin, regarded as the guardian of warriors. The Hata Clan considered him their guardian Kami.

According to the Kojiki and the Nihonshoki, Ōjin was the son of the Emperor Chūai and his consort Jingū. As Chūai died before Ōjin's birth, his mother Jingū became the de facto ruler. The legend, presumably concocted much later, alleged that the boy Ojin was conceived but unborn when Chuai died. His widow, Jingū, then spent three years in conquest of a promised land, which is conjectured to be Korea. Then, after her return to Japanese islands, the boy was born, three years after the death of the father. Either a period of less than nine months contained three "years" (some seasons), e.g three harvests, or the paternity is just mythical and symbolic, rather than real. Ōjin was born (in 200 according to the traditional but untrustworthy TC date timetable;, realistically however sometime in late 300's) in Tsukushi on the return of his mother from the invasion of Korea and named him Prince Hondawake. He became the crown prince at the age of four. He was crowned (in 270) at the age of 70 and reigned for 40 years until his death in 310, although none of the TC dates around his reign have any historical basis. He lived in two palaces both of which are in present day Osaka.

He was recorded as the father of Emperor Nintoku, his successor.
