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.
Emperor of Japan
In Japanese mythology, according to "Kojiki" and "Nihon Shoki", the Emperor and his family are said to be direct descendants of the sun-goddess Amaterasu. During World War II, the role of the Emperor as head of the Shinto religion was exploited, which resulted in the creation of State Shinto and an Imperial cult. Following the end of the Second World War, the Allies issued the Shinto Directive which abolished the state support for the Shinto religion, leading to the Humanity Declaration of the incumbent Emperor which refuted the idea that the Emperor is a living divine being, and dismissed the importance of "myths and legends" for the Emperor's status. However, the Emperors have continued to perform many traditional ceremonies privately.
