Mon-in Kogi served as a lady-in-waiting to the Imperial Court before marrying the emperor. Late in life she entered a monastery to become a priestess (1336).
Mon-in Kogi married Emperor Gofushimi, to whom she bore two sons (later known as Emperor Kogon and Komyo).
Emperor Go-Fushimi was the 93rd emperor of Japan, according to the traditional order of succession. His reign spanned the years from 1298 to 1301. This 13th-century sovereign was named after his father, Emperor Fushimi, translates literally as "later" and thus, he is sometimes called the "Later Emperor".
Emperor Kogon was the first of the Emperors of Northern Court during the Period of the Northern and Southern Courts in Japan. His reign spanned the years from 1331 through 1333.
Emperor Komyo was the second of the Emperors of Northern Court, although he was the first to be supported by the Ashikaga Bakufu. According to pre-Meiji scholars, his reign spanned the years from 1336 through 1348.
