Go-Kōmyō's reign spanned the years from 1643 through 1654.

This 17th-century sovereign was named after the 14th-century Nanboku-chō Emperor Kōmyō and go- (後), translates as later, and thus, he could be called the "Later Emperor Kōmyō". The Japanese word go has also been translated to mean the second one, and in some older sources, this emperor may be identified as "Kōmyō, the second", or as Kōmyō II".

Events of Go-Kōmyō's life Tsuguhito-shinnō was granted the title of Crown Prince; and the following year, he became Emperor when Empress Meishō abdicated. His sister stepped down from the throne and the succession (senso) was received by the new monarch. Shortly thereafter, Emperor Go-Kōmyō is considered to have acceded to the throne (sokui). The events during his lifetime shed light on his reign. The years of Go-Kōmyō's reign correspond with a period in which Tokugawa Iemitsu and Tokugawa Ietsuna were leaders at the pinnacle of the Tokugawa shogunate.

Kugyō is a collective term for the very few most powerful men attached to the court of the Emperor of Japan in pre-Meiji eras. Even during those years in which the court's actual influence outside the palace walls was minimal, the hierarchic organization persisted.

In general, this elite group included only three to four men at a time. These were hereditary courtiers whose experience and background would have brought them to the pinnacle of a life's career.
