Emperor of Japan
The current Emperor on the throne is typically referred to as "Tennō Heika" (, "His (Imperial) Majesty the Emperor"), "Kinjō Heika" (, "His Current Majesty") or simply "Tennō", when speaking Japanese. The current Emperor will be renamed "Daijō Tennō" (, Retired Emperor), often shortened to "Jōkō" (), upon his planned retirement on 30 April 2019, and renamed "Heisei Tennō" () after his death and will then be referred to exclusively by that name in Japanese. In Japanese culture, it is considered a major faux pas to refer to a living Emperor by his posthumous name, although the posthumous name is the same as the era, which is used in official documents.
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.
