Emperor Go-Komatsu (August 1, 1377 - December 1, 1433) was the 100th emperor of Japan, according to the traditional order of succession. He is officially considered a pretender from May 24, 1382 to October 21, 1392, when Emperor Go-Kameyama abdicated. He is understood to have been a legitimate emperor (the 100th sovereign) from that date until October 5, 1412. According to pre-Meiji scholars, his reign spanned the years from 1392 through 1412.
