Go-Komatsu, emperor of Japan (b. 1377)
Emperor Go-Komatsu (後小松天皇, Go-Komatsu-tennō, 1 August 1377 – 1 December 1433) was the 100th emperor of Japan, according to the traditional order of succession, and the sixth and final Emperor of the Northern Court.

He is officially considered to have been the Northern pretender from May 24, 1382 to October 21, 1392, when upon Emperor Go-Kameyama's abdication, Go-Komatsu is understood to have been a legitimate emperor (the 100th sovereign) from that date. In 1392, following the post-Nanboku-chō unification of the two formerly contending courts, the Southern Emperor Emperor Go-Kameyama reached an agreement with Go-Komatsu to alternate control of the throne between the Northern and Southern courts on a ten-year plan which effectively signaled the end of the southern court's claims to sovereignty. However, Go-Komatsu reneged, not only ruling for 20 years until his own abdication on October 5, 1412, but was succeeded by his own son, rather than by one from the former Southern Court. According to pre-Meiji scholars, Go-Komatsu's reign as a legitimate emperor spanned the years from 1392 through 1412. The present Japanese Imperial Family is descended from the

three Northern Court emperors.

This Nanboku-chō "sovereign" was named after the 9th-century Emperor Kōkō, and go- (後), translates literally as "later." Jien's Gukanshō explains that Kōkō was called "the Emperor of Komatsu". The 14th-century pretender and emperor may be called the "later Emperor Kōkō" or the "later Emperor Komatsu". The Japanese word go has also been translated to mean the "second one;" and in some older sources, this would-be emperor may be identified as "Komatsu, the second", or as "Komatsu II."
