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.
Controversies regarding the role of the Emperor of Japan
In the Meiji Constitution of 1889, the emperor was sovereign and was the focus of the state's legitimacy. The preamble stated, "The rights of sovereignty of the State, We have inherited from Our Ancestors, and We shall bequeath them to Our descendants." In the postwar constitution, the emperor's role in the political system was drastically redefined. A prior and important step in this process was Emperor Hirohito's 1946 New Year's speech, made at the prompting of General Douglas MacArthur, renouncing his status as a divine ruler, without however repudiating that he was a descendant of Amaterasu as arahitogami. Hirohito declared that relations between the ruler and his people cannot be based on "the false conception that the emperor is divinity in human form ("akitsumikami") or that the Japanese people are superior to other races."
