order of succession.[4][5] Very little is known about this Emperor due to a lack of material available for further verification and study. Kaika is known as a "legendary emperor" among historians as his actual existence is disputed. Nothing exists in the Kojiki other than his name and genealogy. Kaika's reign allegedly began in 158 BC. He had one wife and three consorts whom he fathered five children with. After his death in 98 BC, one of his sons supposedly became Emperor Sujin.[3][6]
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.[2] His empress mother was named Utsushikome, who was the daughter of Oyakuchisukune.[citation needed] Before he was enthroned sometime in 158 BC, his pre-ascension name was Prince Nikohiko Ō-hibi no Mikoto.[6] The Kojiki records that he ruled from the palace of Sakaihara-no-miya (軽之堺原宮, and in the Nihon Shoki as 軽境原宮) at Karu in what would come to be known as Yamato Province.[5] 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.[6] 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.[7]

The existence of at least the first nine Emperors is disputed due to insufficient material available for further verification and study.[8] Kaika is thus regarded by historians as a "legendary Emperor", and is considered to have been the eighth of eight Emperors without specific legends associated with them.[b] The name Kaika-tennō was assigned to him posthumously by later generations.
Like Emperor Kōshō and Emperor Kōrei, there is a possibility that "Kaika" could have lived instead in the 1st century (AD). Historian Louis Frédéric notes this idea in his book Japan Encyclopedia where he says "more likely early AD", but this remains disputed among other researchers.[6][11] The first emperor that historians state might have actually existed is Emperor Sujin, the 10th emperor of Japan.[7] Outside of the Kojiki, the reign of Emperor Kinmei[c] (c. 509 – 571 AD) is the first for which contemporary historiography is able to assign verifiable dates.[14] The conventionally accepted names and dates of the early Emperors were not confirmed as "traditional" though, until the reign of Emperor Kanmu[d] between 737 and 806 AD.[9]
. According to legend, the first Japanese Emperor was Jimmu. Along with the next 13 Emperors, Jimmu is not considered an actual, historical figure. Historically verifiable Emperors of Japan date from the early sixth century with Kimmei.
