Legendary narrative In the Kojiki and Nihon Shoki, only Kaika's name and genealogy were recorded. The Japanese have traditionally accepted this sovereign's historical existence, and an Imperial misasagi or tomb for Kaika is currently maintained; however, no extant contemporary records have been discovered that confirm a view that this historical figure actually reigned. Kaika was born sometime in 208 BC, and is recorded as being the second son of Emperor Kōgen. His empress mother was named Utsushikome, who was the daughter of Oyakuchisukune. Before he was enthroned sometime in 158 BC, his pre-ascension name was Prince Nikohiko Ō-hibi no Mikoto. The Kojiki records that he ruled from the palace of at Karu in what would come to be known as Yamato Province. Emperor Kaika had a chief wife (empress) named Ikagashikome, along with three consorts of which he fathered five children with. Kaika ruled until his death in 98 BC; his second son was then enthroned as the next emperor. His son/heir to the throne was posthumously named Sujin by later generations, and is the first emperor that historians say might have actually existed.
