Usage notes
Intentionally lowers the title of “emperor” to “king”. This was initially used in the context of a Sinocentric system that proscribed that the emperor of China was the only true emperor (皇) while the leaders of other states in the Sinosphere were kings (王).

This title is commonly used by the South Korean media; however, official government communication have used (emperor, a direct reading of the Japanese term) since at least 1998.
