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 Yōzei
Yōzei was succeeded by his father's uncle, Emperor Kōkō; and in the reign of Kōkō's son, Emperor Uda, the madness re-visited the tormented former emperor:Yōzei lived in retirement until the age of 80.
The actual site of Yōzei's grave is known. This emperor is traditionally venerated at a memorial Shinto shrine ("misasagi") at Kyoto.
