Emperor Go-Kōmyō (後光明天皇, Go-Kōmyō-tennō, April 20, 1633 – October 30, 1654) was the 110th emperor of Japan, according to the traditional order of succession. 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".
