Records of heads of state
Officially, the current Emperor of Japan, Akihito is the 125th in line from the first emperor Jimmu, who is variously believed to have reigned in the 1st or 7th century BC. The earliest documentary evidence is only for the 29th emperor, Kinmei (AD 509–571); however, this is sufficient such that even the most conservative of estimates still places the Japanese imperial family as among the oldest lines in the world today.
Empress Jingū
, occasionally known as , was a Japanese empress who ruled beginning in the year 201.
Her father is Okinaganosukunenomiko (息長帯比売命) and her mother is Kazurakinotakanukahime (葛城高顙媛) who is the descendant of Amenohiboko (天日槍) the legendary prince of Korea. The consort to Emperor Chūai, she also served as Regent from the time of her husband's death in 201 until her son Emperor Ōjin acceded to the throne in 269. Up until the Meiji period, Jingū was considered to have been the 15th Japanese imperial ruler, according to the traditional order of succession (hence her alternate title "Jingū tennō" 神功天皇); but a re-evaluation of the extant historical records caused her name to be removed from that list; and her son, Emperor Ōjin, is today considered to have been the 15th sovereign.
