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.
Politics of Japan
On 2 June 2010, Hatoyama resigned due to lack of fulfillments of his policies, both domestically and internationally and soon after, on 8 June, Akihito, Emperor of Japan ceremonially swore in the newly elected DPJ's president, Naoto Kan as prime minister. Kan suffered an early setback in the Japanese House of Councillors election, 2010. In a routine political change in Japan, DPJ’s new president and former finance minister of Naoto Kan’s cabinet, Yoshihiko Noda was cleared and elected by the Diet as 95th prime minister on 30 August 2011. He was officially appointed as prime minister in the attestation ceremony at imperial palace on 2 September 2011.
