Emperor Antoku
There are two styles in emperors' posthumous names, namely Chinese style, and Japanese style. In addition to the appellation "Tennō" (天皇, "heavenly sovereign", usually translated as "Emperor") that is a part of all Japanese emperors' posthumous name, most of them consist of two kanji characters, although a few consist of three. Some names are given several generations later—this is the case for Emperor Jimmu and Emperor Antoku, for example. Others are given immediately after death, like that of Emperor Monmu.
