Emperor of Japan
Currently, the Emperor of Japan is the only head of state in the world with the English title of "Emperor". The Imperial House of Japan is the oldest continuing monarchical house in the world. The historical origins of the Emperors lie in the late Kofun period of the 3rd–7th centuries AD, but according to the traditional account of the "Kojiki" (finished 712) and "Nihon Shoki" (finished 720), Japan was founded in 660 BC by Emperor Jimmu, who was said to be a direct descendant of the sun-goddess Amaterasu. The current Emperor is Akihito. He acceded to the Chrysanthemum Throne upon the death of his father, Emperor Shōwa (Hirohito), in 1989. The Japanese government announced in December 2017 that Akihito will abdicate on 30 April 2019.
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.
